How to choose a good sound

Since the Taiwan people began to write audio equipment comments since,various nouns, adjectives related to audio equipment performance has been in a less precise circumstances; moreover, many nouns or adjectiveshave also been reviewers or readers misunderstanding, to avoid misuse,should not have a lot of confusion and contradiction. Investigate its reason,Chinese "Mr. almost" personality can not break away from the responsibilityof nouns, domestic and foreign native miscellaneous also causes; finally,noun, critics and readers could not used in equipment reviews of adjectives in thinking is an accomplice. Therefore, many commentators even play word games, water filled page for the poor. To be straight to the point,many essays should be precise, solid state from a distance.

Many years ago, I was deeply these matters the bitter, once wrote an article"stereo ten" essay, was simply that I review equipment direction. Several years later, I found the "stereo ten" already unable to meet therequirements of "accurate", but also including myself, many essays will stillfrom idleness was not well. Therefore, the brain will plan to re look at how to write, equipment reviews next detailed breakdown. Let me, "audio forum"commentators, and readers will have a clear guide. Only in this way, the word in order to achieve the minimum distortion; only in this way, equipment reviews articles can be more solid, refined, and having substance in speech.

Perhaps, my thinking is still not well, the following twenty item may still have oversight or worthy of the place. However, over the years "stereo twenty"has become the mainstream thought generally accepted Taiwan audio industry, this is an indisputable fact. I hope the new readers after carefully read this article, can be accurate to cultivate their ability to judge the basicsound equipment. In this way, will not be many uncertain, with words,ambiguous two comments.

The first to sound: sound

Tone refers to the sound quality, many people put it with the "tone"confused. What is called the quality of voice? When you say a pair of shoes with good quality. You must mean the fit, comfortable, durable, notits shape looks stylish, from time to time. Similarly, when you said something in audio equipment sound quality is good, bad, you don't meanto, its hierarchical location such as can be, but to this piece of equipment"Naibunai listen"! As if not durable, resistant to don't fit me. A pretty good sound equipment, its performance in the outer is comfortable, resistant to.You don't have to investigate it sounds, listen to reason, that is to specialists, as long as you use your ears to judgment. Some equipment,powerful, fast, the resolution is also strong, but not durable listen, it may be the quality problem. A good piece of audio equipment, its quality should be like a good voice, let a person listen not greasy.

May I say you think very abstract. In fact, I can give you is listed to explain.When you say the cloth, you can say: the material of good quality. When you eat a steak, you would say: this steak meat quality is very good. When you praise a child, will say: the child's quality is good. So, when you hear asound equipment or a musical instrument, you can also say: it sounds very beautiful. From these examples, you can clearly know that "quality" is theinherent nature. Noble, good quality, very beautiful is representing this piece of equipment is good - natured, it sounds very comfortable. I can say that quality is the most important part of audio equipment, so I put it in thefirst.

Second sound: sound

Tone refers to the voice color. In English, sound quality (TONE QUALITY)and tone (TIMBRE or TONE COLOR) see at a glance what it means is not the same thing. But in Chinese, tone quality are often mixed, misuse. We often hear: the violin sound really cold, the violin sound really warm, saying,this is a violin tone. The sound is the light, there is a color, but it is not with the eyes, but with the ear. Usually, the more the more soft warm voice tone;tone more cold voice more hard. Too soft or too hard of course is not very good. Sometimes, the timbre can also use the "noble", "beauty" and other words to describe, basically it is also one of the nature. However, like cloth,cloth refers to its material, cloth color is the color, it still has obvious boundaries. In the audio commentary, sound like color in general, refers toits unique color. Some equipment tone yellow, some partial white, somecold, or you can say it is a bit about Mao blue. In short, audio equipmentsuch as instruments, almost can not break away from the more expensivethe more beautiful the fact tone. A $two million violin sound may beauty with a golden color luster; and a NT $five thousand violin sound likely fadedpainting. Although each person different views, but, "beauty" is arecognized "consensus", you can't say an upturned nose is the embodiment of beauty "; the same you cannot say a cold blue tone of theequipment is beautiful. This is our consensus on sound beauty.

Audio third: distribution and control in each frequency band, high, lowvolume.

This project is very easy to understand, but also very easy to produce themessage on a misunderstanding. How to say? Everyone will say: the loudspeaker treble, bass too little too strong. This is high, medium, low frequency quantity feeling distribution. The problem is if the from 20Hz to20KHz bandwidth with only three if divide, it will have a "not accurate"confusion. What your bass is there? Many low? In order to describe the text more accurately, it is necessary to subdivide the bandwidth of the 20Hz-20kHz. According to the United States of America and the Stereophile TASmethod is very simple, they have high, low, in each section is subdividedinto three sections, namely "low frequency, intermediate frequency, highfrequency" method. This method is twelve on average, a law. But it had some minor problems in the translation in the Chinese people, such as "if"low we called the "low" or "low frequency"? Then higher frequency? "Highfrequency"? For the Chinese, foreigners this method is probably not going to work. Therefore I will reference instrument long before the bandwidth, as well as the orchestra calls to voice, the frequency of 20Hz-20KHz is divided into seven segments of extremely low frequency, low frequency, low frequency, intermediate frequency, high frequency, high frequency, inextremely high frequency. The seven section of the Chinese used to call,but remember, don't confuse.

Elf: from 20Hz-40Hz this eight degree I called elf. Within this bandinstruments rarely, only the bass, bass bassoon, tubal, organ, piano and other instruments can be so low. Because of the extremely low frequency is not the most beautiful voice musical instrument, so composers rarely notes are written so low. Unless it is pop music with synthesizers sedulous arrangement, or very low frequency sound fans for not really good. Somepeople mistake a thing, said that although the tone of the instrument is notso low, but can be low to pitch the overtone. In fact, this is not correct,because the tone of the instrument is the lowest note, the sound will only be two times, three times, four times, five times... The upward climb, but will not have to. It's like you would a taut string, string length of vibration frequency is pitch, 1/2, 1/3, 1/4, 1/5... Vibration chord is overtone.Fundamental and overtone is the sum of musical instruments. In other words, Violin and flute even pitch (pitch) the same tone, also can have the different manifestation.

Frequency: the frequency from 40Hz-80Hz called frequency. The band has what musical instrument? Drums, bass, cello, bass bassoon, bassoon, BassTrombone, bass clarinet, tubal, France, etc.. This band is composed of low frequency based and big hero. Usually, people will mistakenly think that thisband is extremely low, because it sounds really has very low. If thefrequency quantity feeling too little, and the feeling of surging must not; and can lead to high frequency, high frequency of prominent, makes the soundto lose balance, not durable listen.

Low frequency: 80Hz-160Hz, I called the low-frequency. This band is aTaiwan audio fans the most headache, because it is caused by the culpritdetonation burst of ear. Why is this band are especially vulnerable topeak? This small room for long, wide, high dimension. Most of the people in order to remove the annoying peak, devoting himself to absorb the band,that keep your ear to boom came. Unfortunately, when you ears sounds notwent crashing, low frequency and intermediate frequency is below mayhave with the low frequency absorption was depressed, and the soundbecame thin, the lack of a sense of. Unfortunately most people only because the peak disappears and that this situation is right. This is many people voice is not rich is one of the reasons. The band instruments including the mentioned just now in the low frequency band instrument.Yes, timpani and bass also should be added.

MF: from 160Hz-1280Hz across the three eight degree (320Hz, 640Hz,1280Hz) between the frequency I called intermediate frequency. This bandalmost all instruments, vocals are included, so is the most important band.Readers are the biggest misconception about musical range also occurs inhere. For example, most of the violin in this frequency range, but most people mistakenly think that it is very high; don't think soprano vocal rangeis very high, generally speaking, her highest range is in intermediate frequency limit.

From the description above, you must also understand that if is howimportant in the sound. As long as the frequency of depression, the performance of voice immediately became thin. Sometimes, this is easilyinterpreted as "false identity". I believe there are many audio fans in the situation without knowing if depression. The importance of this band alsocan be analyzed from two way loudspeaker crossover points. General twoway loudspeaker crossover points mostly in 2500Hz or 3000Hz, that is to say, more than 2500Hz from the tweeter is responsible for 2500Hz,following by the bass monomer is responsible for. This 2500Hz is about twotimes that of 1280Hz, that is to say, for fear of bass monomer students too much crossover distortion in the frequency limit, designers get the crossover point increase to two times the upper limit, if so, if the most perfect can be issued by a single body in the bass.

If this argument is correct, tweeter do what use? If you have an ear to thetweeter, you will hear a "hissing" sound, that is where most of the overtone.If there is no tweeter hissing sound, music with a bass monomer, it must bedull unbearable. Of course, if the three sound road designed speaker, thissection if most will be included in the Alto monomer.

High frequency: 1280Hz-2560Hz called from the middle and high frequency.The band has what musical instrument? The violin is about 1/4 higher in the half range, Viola, flute, clarinet, limit the oboe, piccolo bass trebledomain is domain, cymbals, triangle etc.. Please note, the trumpet is notthis band domain. In fact, the high frequency is easy to identify, as long as the treble treble strings and woodwind domain groups are in high frequency. This band is a lot of people will think is high, so please pay special attention to.

High frequency: the frequency domain from 2560Hz-5120Hz, I called thehigh frequency. The frequency domain for playing musical instruments, has been rarely have the opportunity to become involved in. Because apart from Violin range limit, piano, piccolo altissimo, other instruments are not appear in this band. From the loudspeaker crossover points, we can find that the frequency domain all appear in the tweeter in. As I said earlier,when you will ear close to the tweeter, you hear is not a musical sound, but a hissing sound. The tweeter performance, can once again prove tweeterrarely issued pitch instruments or voices, high overtone it just a pitch.

Extremely high frequency: 5120Hz-20000Hz from such a wide frequency band, I called the extremely high frequency. The high frequency has littleinstrument of the facts, all instruments and vocals to accommodate theextremely high frequency overtone. General instrument overtone mostlymore high energy is smaller, in other words, tweeter to create very keen,can clearly regeneration very subtle tone. From here, a troubled the hornmonomer thing happened, that is how to satisfy both sides? What is the"endowment"? Have you ever thought of, if a tweeter to clear regenerationall subtle overtones, fling caution to the winds into the design of the currentcan be very small push the diaphragm, so also the tweeter which is responsible for the high energy, high and medium frequency is very likelywill often in a state of distortion, because the two frequency bandsextremely high frequency energy than too much. This is currently on the market many speakers extremely high frequency very clearly, one of the reasons is likely to be harsh.

You remember the previous Spentdor SP-1 horn? It is the three sound road design, the three sound road? In the bass, treble monomer monomer,super tweeter three road. The tweeter is responsible for frequencies above 13000Hz. I remember a lot of people "understand", why SP-1 has supertweeter, but the voice is so soft? Should be very sharp to ah! Now I think you should know! SP-1 design focus on the tweeter not distortion, and can regenerate extremely high frequency. This is one reason why SP-1 sounds very comfortable, with music.

After segmentation, in high, low-frequency know, then we should controlforce sense "discussion". Sense of course refers to the quantity, is what wesay: the treble, bass is much less. While the control force usually refers to "the ability to control the low frequency and high frequency. Someequipment, low loose, some with elastic. We will say that the low frequencycontrol. Some equipment to hold high, let it not shoot even earsuncomfortable, we say it has good high frequency control. Please note, the amount of each band sense does not represent the true quality ofequipment, mutual collocation of equipment between the volume size is important. The control force is good or bad can be said to be the equipment itself superior, inferior.

Fourth sound: sound field performance

What is the sound field "? In the United States, "Sound Field" and "SoundStage" is the two noun. "Sound Field" refers to the voice filled space;"Sound Stage" refers to the stage band arrangement (including wide, deep,high, low). In Taiwan, we call the "field" actually means "Sound Stage",because it is "sound stage" or "console" people are not take the words too literally. As for "Sound Field", we have been replaced by another noun, that is "sense of space". Therefore, when we refer to "sound field shapes",refers to your equipment recycling Orchestra arrangement.

The frequency response curve of the uneven distribution and loudspeakerdirectivity, room acoustic reflection conditions, some sound field is concave shape, some are wider than the depth; some are large depth to width.Some of the sound field is four four square shape, no concave. The soundstage regeneration of different shape, I called the sound field shapes. The sound field shapes the best course to meet with the recording of the original. Here I would like to propose a different note: site performancerecording, the band width to depth is arranged; but in the studio, often in order to sound effects, will change the orchestra arrangement, usually the depth will be stretched, especially percussion instruments will be placedfarther. In this way, we are not in the hall to see the arrangement. Criticalreaders and critics may not detect.

The sound field position

In addition to the "shape", the sound field and "location" problem. This includes the sound field before and after, high, low. Some equipment will make the entire sound field approximation to the listener; some are back.Some of the sound field sound will feel floating in midair; others like sitting in the hall of the two floor at the stage of general. Many reasons sound fieldposition, as the speaker placement and frequency response of the uniformor not are the major influencing factors. How an ideal sound field position should be? Out of the bass, Cello Sound from the low place, violin position than bass and Cello high; if the recording band has a low before higharrangement, sound field will have a low to high appeared. Brass is very likely to a higher position.

As for the entire sound field height? Usually you sit two head height should be slightly lower height of the sound field. In other words, the violin shouldin view of the above, cello, double bass in the eye. Brass is at least as high or higher and the violin. Before, after the position for the sound field should be there? Should extend back in the "front line" start horn. Of course, the optimal location of the sound field is not easy to get, because it and listen to the software also has a great relationship. Usually, after extended along a line from the horn is easily obtained, however, not be "retraction" too much.

The sound field width

Often hear fancier boast: "I not only sound field beyond the horn, wide attwo side walls, and even breaking the wall. "This sentence in the layman it,is simply Arabian nights. In my opinion, it is only a bit of an exaggeration. I think a lot of music fans have this experience, I don't need to waste any more words. Generally speaking, the sound field width is wide at the side wall. As for breaking the wall, then I'm afraid we a little imagination. At least,in my case, I want "with the eyes can see" sound field where it counts,outside the wall. I can't see it, I can't be sure where it. So, the sound fieldwidth me in just only within my walls. Arcane Victor sound source

The sound field depth

This is what we usually call "depth", now I give it back to the sound fielddepth. Why is not the same as before, it with the sense of hierarchy, sense of location coordinate? Because the level and location are not talking about the sound field, and the sense of depth range is still belongs to the sound field, so, I will change it into "the sound field depth" instead of "depth" call.As with "the sound field width", many people would say that his home field depth has been breaking the wall, deep into the street. Of course this is only to meet their own adjectives and others.

The real "field depth" refers to the sound field in the front line of musical instruments and the last line of musical instruments distance. In other words, it is very likely that the violin and bass drum, timpani distance. "Wide to adjacent, deep on the street" this should be included in the back and say"sense of space". Some equipment or the environment due to low frequency or low frequency too much, so the location before the drums andtimpani Chong, at this time, the sound field depth is certainly very poor.Another example, some sound field position to shrink back, the results being mistaken for sound field in the depth of well, and that is wrong. I believe, as long as you hold the violin to the timpani, bass drum the distance between "this sentence is not wrong.

Fifthly, density and weight sound: sound.

Density as so-called sound one kilogram of cotton and a kilogram of iron,iron density of course much more. Therefore, although the two the same weight, but the iron to give people sense of weight would be much larger.Sound density sound is what feeling? String with viscous feeling, thick and full band, percussion knocked up will have the air vibration sense.Instruments and vocals all should have the sense of weight. However, most of the audio game are not sound density and weight of good sense. This feeling I guess the adequacy and intermediate frequency, frequency andpower of the full. Density and weight sound a good sense of what good?Let the instruments and vocals sound more stable and more like the real.

Audio sixth: transparency

Transparency is almost a noun can only sense, can only be sensed. Someequipment sounds clear and matchless, others like cast a layer of fog, as long as there is a replacement of experience of people have this feeling.Transparency is "stereo twenty" in a very important aspect, because if thetransparency is poor, will also affect the joint judgment on the.Transparency is the best soft, sounds ears don't fatigue; transparent feeling poor like hurt the eyes of the sun, although see clearly, but verysad. Most of the audio equipment can not reach the level of transparency isclear and soft, and can only clear. If we can reach the "clear and soft", thatpiece of equipment value may not be low.

Audio seventh: a sense of hierarchy

Layering is easy to understand, it refers to the instrument by going after a row spacing can clear regeneration. In television, dark gray and black can distinguish words have administrative levels feeling. Audio versa, orchestraarrangement not mixed together is a good sense of hierarchy. What is more, we want to hear music and musical instruments of the spacebetween, so you can have the best sense of the level.

Chapter eight: sound localization feeling

As the name implies, sense of location is the location "in there". You poor sense of focusing not positioning, knot like a poor sense of location is not,equipment phase distortion will lead to the positioning of the drift; and evenspace direct sound and reflected sound (generally refers to the proportion of poor high frequency reflection too strong) will lead to inaccurate positioning. For example: it is very hot in the summer, the asphalt road will take the gas. If you walk on the road, will feel the object image will be gone with the wind. It's like we sound field instrument positioning will drift. If you have astigmatism and forgot to wear glasses, it is also the location specific performance are not good. In short, poor sense of location may be caused by many reasons, we whether it is how to form, we are asking is instruments or voices to be raised and clear "fixed" there, not when the movable do not move, not when the chaos can not be arbitrary.

Sound: ninth to live

The so-called living presence can be said to be on the other side of the transient response, the sense of speed, strength contrast. It allows you to listen to the music is very lively, not dead Shen Shen. This is the music good or not is an important factor, as an excellent conductor can turn the music command was full of angry; and poor command will often get deadShen Shen music. This is the sense of live music.

Tenth: the sound knot image force and the sense of form

As the name implies, is the ability of imaging aeriality of audio-visualcondenses into entity; in other words, is to let the voices or instrumentsshowed that stereoscopic form. In the past, I put it into "the sense of form.Then I thought, that imaging can contain more complete meaning, so as toknot image force and the sense of form. The knot image force good stereoequipment will make video more relief, more three-dimensional sense. It isaudiovisual profile I often say shadow more clearly.

Audio eleventh: resolution

The term most let know best, played the camera knows lens resolutionquality gap; watch TV people know their own TV can make hair analysis a black no mixing of resolving power is good performance. Good audio equipment, express, and even the tiniest of complex things can be clear,this is the resolution.

In fact, more details and the black level is clearly the resolution results, like the sense of space can also be incorporated into the sound field is the same. But the resolution does not represent the details of regeneration andall levels of sense. For example, by going after a row of sense of hierarchyis not entirely caused by the resolution; moreover, if the sense of hierarchyinto the resolution, it is unable to make a clear explanation of individualnouns. Therefore, I would do everything possible to separately, readersneed to know "between sound twenty to" each other has close relationshipto.

In general, if minor changes (low level) can be shown clearly, then theresolution of this equipment is good. Since the resolution usually low, sothere is no resolution at high electric? Yes, of course. In the extremebursting can parse everything very clearly, that is the high level resolution.

Audio twelfth: the sense of speed and transient response

In fact, the sense of speed is the transient response results, specific performance is equipment rise time and slew rate. Foreigners often will thisas a transient response without the sense of speed. However, Taiwancustom language is the sense of speed. For the old, the sense of speedthan the transient reaction is easy to understand. Basically, the two nouns refer to the reaction speed, equipment. I think, this would not have to do more to explain.

Sound: thirteenth to contrast with dynamic contrast

The contrast is also a dynamic contrast foreigner said, also is the contrast between loud and quiet. Generally speaking, the contrast can also be divided into "the strength of strong contrast between" and the "minimum" comparison. We often say that the dynamic great classical music refers to the maximum and minimum sound sound contrast; rock music while loudly, but not its size and sound, so we say it aloud, but the dynamic contrast is not.

What is the dynamic contrast tiny? It is very close to the subtle contrast. This subtle contrast like water ripple like, far look like immovable, near to see just know it is always subtle fluctuations in the. The contrast with the most facile argument should be like this: the contrast which is over the rocks. The waves; the minimal fluctuation intensity contrast is the wind.

Fourteenth: acoustic instruments and voices in proportion to the size of

What musical instrument line shape, much is on? What voice to a wisp of such as chain? Or should have the flesh smooth? This issue has been haunting sound game. Idealists believe should be according to the actual band size scaling in home listening room. Actually, it's out of the question. I cite a simple example. When the piano and violin playing a sonata, piano form do not know how many times more than the violin (volume versa). If you do not increase the volume when recording the violin, violin piano mask is often not (often is the live concert so). So while recording, recording engineer will try to balance the violin sound. Again said the whole orchestra and the violin concerto performances do, if fully scaled down, then the violin should small cannot again small, rather than in CD we have heard so clear, strong. Therefore, the correct "instruments and vocals size proportion", not blindly to shrink, but according to the size of the sound of music. Musical instruments, vocal.

In fact, problems of instruments and voices in proportion to the size of the most noteworthy is not scaled down or not, but because of the frequency response curve of the distortions caused by the misunderstanding. Your room such as severe peak in about 100Hz, timpani knocked up will be particularly large, especially strong; Cello, double bass. This is the real error ratio. Therefore, in the evaluation of writing "the instruments and vocals in proportion to the size of" influence, special attention should be paid to the distortions caused by frequency response curve.

Fifteenth: acoustic instruments and voices, air quality

The term "texture" is rather abstract, we often say this furniture wood texture is very good, this set of sofa leather texture is very good; or the marble texture good. From this example, we can understand, the so-called "texture" Beijing refers to the object "material nature". However, the texture we said is not sound, but playing musical instruments, percussion contact occurs the moment of action texture. Therefore, when we say: "the violin string rubbing the texture is very good", means "it recorded is like a violin". When we say: "cymbal percussion texture is very good", that "it knocked up like a real". Conversely, when we think of "the violin string rubbing texture is not" said that "it is not true.". Thus, we can clearly understand, the so-called texture also means "fidelity". Laser disc has just launched, everyone thought the violin sound unlike, refers to the brush texture unlike.

"The sense of form is easier to understand, when we listen to the clarinet playing, we say that it is the sense of form is good, that is" a fax. ". In short, texture and sense of form is "synonymous with fax or not.". As to the "air" is what? When we describe pull outs, keyboard instrument, we use is "a musical texture is very good.". However, when we describe wind instruments, we do not usually use the "texture" two words, with "air", that is to say blowing feeling. Say it more clearly, "air" refers to the feeling of acoustic vibration, and the texture is "contact" most instant feeling. Of course, in addition to playing string group of brush texture, it has the string resulting in air "air".

Audio Sixteen: details of regeneration

Details about all the details of a murmur of musical instruments, the church sound fine regeneration and recording space. A piece of audio equipment details regeneration amount easily via AB Test. Why do some equipment regeneration with more details? I think that with low distortion, high signal-to-noise ratio, high sensitivity, resolution, transparency and so on. Equipment sounds less boring flat details: more details of equipment up interesting. A fine piece of audio equipment, recycling the details of course is very rich.

Seventeenth sound: the sense of space

I always say, if a set of sound system (including equipment and space) to "make sound field float", then it must also "can see" the sense of space. Please note, I used the "see" instead of "hear". The sound field and the space really good feeling is absolutely can "see", not only "hear". What is the sense of space? The recording sites three dimensional entity size. To be able to be fully reflected the sense of space, the details perfect regeneration is absolutely necessary, especially the "regeneration hall sound". I can even say that, if you don't hear a complete hall sound, then the "sense of space" cannot complete regeneration.

What is "the church music"? Tang music and "reverb" often is confused. Most people mistake "the church music" is "reverb". In fact, this is two different things. The church sound English is Ambience, reverberation is the English Reverberation. Ambience means, surrounding environment or atmosphere, was later extended to the music hall hall. From the "atmosphere" two words, we can understand it is around us details of the music. In addition to the perceptual significance, Ambience there is a rational explanation, it is a narrow finger first reflection sound into the ear. In other words the first reflection sound and audio delay, we can "feel" the music hall space size. Therefore, if we can't hear the church sound in the software, we cannot "see" the sense of space?

"Reverb" in general explanation, of course also can be said to be reflected sound. However, reverb has a tougher time definition, it refers to a tone burst happens, sound energy decay to one millionth (60dB) of the original length of time. In other words, we usually say: "really rich, the music hall reverb is beautiful", rather long short reverberation. On the other hand, we should not say: "the church music is too short" the music hall, but should say: "the really rich, the music hall hall sound really natural.".

Eighteenth: the whole balance of sound

Each piece of audio equipment and control command in the orchestra, should obtain an overall balance. This is like an orchestra, everyone is a master, but everyone up front head, do not listen to command interpretation, so although the individual performance level is high, but the overall balance of the orchestra is poor. This is not a good band. Similarly, the seventeen elements of a sound equipment are very good, but if you can't put the seventeen elements of a delicate balance, then also must not durable listen. At this time, no matter the resolution and high contrast, did not matter. About this, we can not use the scale to measure up, to distinguish between the overall balance as the orchestra concert to distinguish the quality, only rely on their own rich experience to judge the listening.

In addition, the overall balance of the said there are appropriate amount, frequency distribution, a sense of. For example, the low-frequency basis is better we said is one of them. Steady, steady state called low-frequency basis is low frequency resulting in the music. Most of the music fans hope that music is very thick, rich, rather than low frequency, high frequency, resulting in top-heavy situation. This is a reasonable high, low frequency quantity feeling, which I call the overall balance. Equipment will sound overall balance and good resistance to listen, this is generally known as the music. This incidentally, when you do the horn positioning, first of all to get is the overall balance. Don't to sound field performance, at the expense of mid and low frequency strong. What I mean is: if your speaker is too far away from the wall at the low frequency problems, it should let the horn against a wall before.

Nineteenth: equipment sound personality

Each piece of audio equipment and people in general, has his own personality. Some equipment sounds like a gentleman, like some grease; some like a gentle lady, some warm and like Carmen. Due to different personalities, therefore, in the match must be such as marriage, be very careful. Two fiery equipment together will allow you to digest. On the contrary, two pieces of lukewarm water, slow doctor together to worry you. Therefore, equipment personality cognition is absolutely necessary.

Here I must tell the readers that, according to my long audition audio equipment experience, I think the difference of equipment itself on the personality than the difference between the true quality of equipment. That is to say, the general readers that the equipment is often may be different personality with the personal preferences of the real equipment, quality is often overshadowed by the personality. Therefore, in-depth understanding of the equipment's personality is the absolute necessity. If you don't understand the equipment personality, also cannot do appropriate collocation. In this way, the sound to listen hard.

Audio twentieth: with the recommended

This "Twentieth" is written especially for commentator. A responsible audio equipment commentator should be his own rich experience, recommend to the reader, with appropriate otherwise, readers have read the first nineteen, but because of their lack of other equipment character data or mix of experience, in the end still do not know the rated equipment how to match the surrounding equipment. To the commentators, this is to do a good deed finish. So, when you have finished the nineteen elements, don't forget, recommend suitable combinations for readers.

I emphasize again, improper equipment collocation more often than the equipment itself is a greater impact. Not only is the general audio fans, even sound commentators often because of improper collocation and misunderstand the true ability of the equipment itself, it is very regrettable. In fact, any one commentator as long as heard more, is not a is black and white, good and bad. The comment. Because in this between two often still have many possibilities. So, listen less people more sure of the answer. It seems like most children ask adults during the movie: dad! Those are good? Those are the bad guys? In order to reduce the chance of errors, commentator must first do many matches to be listening to the equipment, and then their collocation is recommended to tell readers.

Conclusion

After reading the "stereo twenty", I believe that some people may think that is too cumbersome, but, in order to promote the sound equipment review standards, in order to let readers understand the context to determine audio equipment quality, I think the complete written or read this twenty if necessary. With this "stereo twenty", commentators for not being a powerful and unconstrained style, readers will no longer confused. So, audio fans can enjoy the music and sound life both rational and emotional.
