Talking about low frequency

<font color="#000000" id="zoom">The meaning of the word low frequency generally refers to the frequency of 20HZ-160HZ. Among the sounds that can be heard by the entire human ear, the low frequency is the basis of the sound and the thickness of the sound. In the band, drums, shellfish, bassoon, organ, piano, electronic synthesizers and other musical instruments can make a thick bass. We can hear these basses very well when listening to live concerts. They are very good and clear. The sound quality of various bass instruments is easily distinguished from each other. There will be no sound or standing waves. But when we leave the scene, go home, try to play equipment at home to get the effect of this scene, then it is not necessarily.
What is the reason? Because it is not easy to get a perfect bass through audio equipment. Maybe some friends will say, what is this, my equipment can make a very large bass, no longer, I can add a subwoofer. In fact, in a set of audio equipment, it is not easy to replay the bass. Especially the replay of the low frequency of 20HZ-80ZH is difficult. Maybe the bass you hear at home is only 200HZ mid-bass, with 8" or Replaying the frequency of the 20HZ-80ZH with a 6" woofer is not an easy task. There are also some examples, such as 29-inch color TV with subwoofer, known as subwoofer or rocket. If you have some understanding of the sound, you know that these TVs can not reproduce the low frequency , and use a very thin plastic box. A 4.5" ordinary elliptical horn, how much low frequency it can emit. It's just a commercial promotion.

Also, in our broadcasts, some low-frequency signals can't be replayed. If we broadcast a 25HZ frequency for everyone on the radio, see what you can hear. In fact, you have not heard anything. If you hear something through the broadcast, it is only the multiplier of this 25HZ, which is the standing wave around 100HZ. Low-frequency signals are replayed, which can easily lead to misunderstandings.

Some very cheap speakers, using the bass reflection in the box, make you feel very enjoyable, but when you carefully understand the difference between the bass and the bass, it makes people feel awkward. The cheap bass is only a matter of quantity and there is no difference in texture, let alone low-frequency dive and control. For low frequencies , you can listen to the sound of the cello. The cello's voice is thick and very textured. Of course, it is best to compare the listening experience of the cello, and to listen to the actual cello sound, it is very beneficial to establish a good listening experience. For example, we can listen to the music that depicts the elephant in the French composer St. Sang's Animal Carnival. This is a low frequency recorded better. It’s funny and cute to show the elephant’s clumsy dance with a bass cello. At the same time, there is also an understanding of the low frequency .



Woofer

Many audio enthusiasts, especially some beginners who are getting started, are very interested in low frequency . When choosing a speaker or audio equipment, they are more focused on listening to the bass. This is not in doubt. Because good low frequency can give people a thick and solid hearing experience, there is a kind of enjoyment of the mountains or the gas sinking dantian. It’s a terrible thing to cry. In fact, good sounds are not all low-frequency , it is difficult to have a sense of balance in the sound, that is, high, medium, low, three-phase frequency is moderate. A speaker is equipped with low, medium and high-pitched horns to complete the entire frequency response.

To complete the replay of the low frequency signal, the first prerequisite is that the diaphragm (which we usually say is the diameter of the paper cone) should be large enough. The larger the cone, the more the air can vibrate to produce the human ear. To the bass. But too much bass diaphragm is unrealistic, because it brings other problems such as the actual size of the speaker and so on. If our family has a pair of 16" woofers, the size is already scary.

Therefore, in the case of not using a large-caliber speaker unit as much as possible, people have already considered using a smaller cone diaphragm to reproduce the low frequency . Thus, using a small-caliber horn to replay more low frequencies requires it to push more air to produce vibration. There is only one way to increase its range of motion. That is, it increases the amount of exercise in an effective time to drive enough air. Therefore, we can notice that the woofer of many high-end fever speakers is not very large, but its vibration stroke is absolutely long, and it stretches to several centimeters. Thus, although the diaphragm is small, the stroke is long and the better bass can be reproduced. So to replay the better bass, it doesn't have to be a big low basin. It is only a stricter requirement for small-caliber units and cabinets, which is not what low-cost speakers can achieve. The world famous Dr. speaker has a subwoofer. It can easily replay the low frequency signal of 40HZ with only two 6" speakers. The 40HZ low frequency signal is close to the bass range of the organ. The woofer is working. Its diaphragm is for piston movement. When pushing forward, the air density in front of the speaker is compressed and the density of the air in the speaker is reduced. When the diaphragm is backward, the density of the air in the speaker increases. The density of the air increases again. This increases and decreases, so that sound waves are formed.

If the speakers are not installed in the speakers, the front and rear sounds will cancel each other out. Therefore, be sure to use a speaker to isolate. Therefore, in a certain sense, all the speakers are for low frequency . The low-frequency sounds that are displayed in audio equipment are indeed what many people like. Whether it is an enthusiast or a person who has just been involved in audio, even some people who know nothing about audio, are interested in low frequencies . Most people prefer those that are powerful, shocking, or as breathtaking as mercury. Hearing some low-frequency sounds that are very good, it will give you a feeling of comfort and relaxation.

Because of this, there will be many audio equipment manufacturers to advertise how good the bass performance of their equipment, how to bass the dive and so on. The minimum frequency that the low frequency can hear as the human ear is 20HZ. What is the reason it makes people like it? Mainly because the low frequency can make the body feel a resonance with the body in addition to the ear, whether it is the skull, bones or skin, or even the oral teeth. In short, all parts of the body produce a resonance due to low frequencies . This resonance makes people feel comfortable and relaxed, both excited and relaxed. This resonance can give people the feeling of releasing stress and relieving tension. Therefore, the pursuit of low frequency is actually a psychological effect and physiological needs.

As a psychological effect and physiological needs, an audio enthusiast should carefully analyze and take it seriously, and must not blindly pursue it. Excessive bass will make the whole sound layerless and turbid. Everyone knows that the truth will take a small step forward and become a fallacy. The world is so big, and so is the sound. The low frequency is of course a basic part of audio music, but if the sound loses balance, once it lacks other intermediate frequencies and high frequencies, it is undoubtedly the end of the game and the other extreme. A good low frequency , in the thick shock, must have its better music content. Otherwise, you can find a manufacturer to produce some low-frequency generators, so that everyone can only listen to the bass. On some audio equipment, good low frequency, deeper than the real dive, very good low-frequency control is not easy. Can not simply agree with the high-priced equipment will be able to obtain high-quality low-frequency , because the low frequency requires too many factors, from the volume of the speaker, frequency division, phase inversion, the quality of the equipment itself, the material and weaving of the connecting line, The actual size of the room, even to the phase of the power plug, etc., will affect the low frequency . Good bass first has to have good control, not too scattered, not too many standing waves, that is, reflected sound; second, not too tight, too hard, too short, dry without sound. The bass often needs a kind of slack, pervasive charm to make people feel good; third, the low frequency is deep. It is very important that you hear that it should be very low bass instead of very much bass.
