The first element of earphone: sound quality


Sound quality refers to the quality of sound. Many people confuse it with timbre. What is the quality of sound? When you say a pair of shoes are of good quality. You must mean that it fits well, is comfortable and durable, not that it looks good and fashionable from time to time. Similarly, when you are talking about the sound quality of an audio headset, you are not talking about its level and positioning, but only referring to its "listening endurance"! It's like wearing or not fitting. An equipment with good sound quality is comfortable and durable. You don't have to explore the reason why it sounds comfortable and endurable. It's a matter for experts. 

You just need to judge with your ears. Some of the equipment is vigorous and powerful, with extremely fast speed and strong analytical power, but it is not durable to listen. That may be the problem of sound quality. A good sound equipment, its sound quality should be like a good voice, let people listen to a hundred not tired. Maybe you think it's abstract. In fact, it is not. I can explain it again. When you mention cloth, you will say: this material is of good quality. 

When you are eating a steak, you will say: this steak is of good quality. When you praise a child, you will say: the child's qualification is very good. 

Therefore, when you listen to a sound equipment or an instrument, you will also say: its sound quality is very beautiful. From the above examples, you can clearly know that "quality" is innate nature. The sound quality is noble, good and beautiful, which means that the nature of the equipment is very good. It makes people sound comfortable. I can say that sound quality is the most important part of sound equipment, so I put it in the first place.


The second element of earphone: timbre


Timbre is the color of sound. In English, tone quality is not the same thing as timbre or tone color. But in Chinese, tone quality and timbre are often mixed and misused. We often hear that the timbre of this violin is really cold and the timbre of this violin is really warm. Sound, like light, is colored, but it is not seen by the eyes, but heard by the ears. Usually, the warmer the tone, the softer the sound; the colder the tone, the harder the sound. Too soft or too hard is certainly not very good. Sometimes, timbre can be described by the words "noble" and "beautiful". Basically, it is one of the natures. However, just like cloth, fabric quality refers to its material, while cloth color refers to its color. 

There is still an obvious boundary between them. In headphone equipment reviews, timbre, like color, refers to its unique color. Some equipment's timbre is yellow, some are white, some are cold, even you can say it is blue with a little worry. In a word, audio headphones are just like musical instruments, which can hardly be separated from the fact that the more expensive the sound, the more beautiful the sound. The timbre of a $2 million violin may be as beautiful as a golden luster, while a violin of NT $5000 may sound like a faded painting. Although everyone has different opinions, there is still a "consensus" on "beauty". You can't say that a person with a sky nose is "the embodiment of beauty"; similarly, you can't say that a piece of equipment with cold blue tone is beauty. This is our consensus on the beauty of timbre.


The third element of earphone: the distribution and control of the sense of magnitude in high, medium and low frequency bands.


The project is easy to understand, but it's also easy to misunderstand words. How to put it? Everyone will say: the high pitch of this pair of speakers is too strong and the bass is too low. This is the quantitative distribution of high, medium and low frequency bands. The problem is that if the bandwidth from 20Hz to 20kHz is divided into three segments, it will inevitably lead to "inaccurate" confusion. What do you mean by bass? How low? In order to make the descriptive words more accurate, it is necessary to subdivide the 20Hz-20KHz bandwidth. 

According to the American TAs and Stereophile's classification method is very simple, they subdivide each segment of high, medium and low into three segments, that is to say, "lower intermediate frequency, intermediate frequency and higher intermediate frequency".

This kind of division is like the law of twelve averages, which is quite regular. However, when applied to Chinese people, there are some translation problems, such as "lower intermediate frequency", which we call "medium low frequency" or "low intermediate frequency"? What about the higher low frequency? "High and low frequency"? Referring to the bandwidth of musical instruments and the appellation of orchestra to sound, the frequency of 20Hz-20KHz is divided into seven sections, namely, extremely low frequency, low frequency, medium low frequency, medium frequency, medium high frequency, high frequency and extremely high frequency. 

The nouns in these seven paragraphs are in line with the common Chinese appellation, and they are easy to remember and can not be confused. The extremely low frequency ranges from 20Hz to 40Hz. This octave is called extremely low frequency. There are few musical instruments in this frequency band. Only the bass, bassoon, tuba, organ and piano can reach such a low range. Because the very low frequency is not the most beautiful range of an instrument, composers rarely write that low. Unless pop music is deliberately arranged with electronic synthesizers, very low frequencies are of little use to headphone fans. Some people mistakenly believe that although the pitch of an instrument is not so low, the overtone can be lowered below the pitch. In fact, this is not true, because the pitch of the instrument is the lowest tone of the tone, and the tone can only be doubled, tripled, quadrupled, quintupled Wait to climb up
