How To Make The Sound Better?

- Apr 29, 2020-

Appropriate volume is a necessary condition to ensure beautiful sound

In fact, whether the sound is good or not depends on whether the operation is correct and the adjustment. Many friends listen to music at the same volume regardless of what music they listen to, thinking that the sound of the recording will naturally be beautiful, and even more terrible, they think that the loud sound is beautiful, so whether they listen to symphony or a single instrument, they use the same Listening to the volume, I heard Teresa ’s singing voice like Hong Zhong, and his petite body turned into a king-size diamond. The violin is large enough to compete with the cello. The treble of the guitar is like a grand piano. When you frowned and felt bored, they were proud of the performance of the above voice, telling you how dynamic his system is, how energetic the singer is, how much recording details ... . Wait, sometimes I do n’t know how to tell him.

Why do these friends listen to music like this? This is purely because they rarely listen to real concerts. I mean orthodox live concerts, like large-scale orchestral performances in two halls. When they have heard the symphony orchestra playing in the same concert hall, the volume of a single instrument when playing and the sound of a real instrument, they can understand what is called proportion, and can they really understand the loudness of the volume when a single instrument plays . In addition to listening to live music, the other most direct way to understand the sound and volume of the instrument is to listen to some live performances without a megaphone system, or simply buy a musical instrument and come back to "operate yourself". At this time, you will not adjust the volume without any criteria. Not only will the sound be distorted, the instrument will be deformed, and the ears will suffer. Over time, your hearing may also be damaged! The highest level of volume control and the best performance of the equipment, of course, is to be able to express the volume of the orchestra, a single instrument or a real person when singing, authentically! This is the volume of 1: 1 that some Hi-Fi friends are pursuing, that is, the volume of the same ratio and the stereo sound field of the same size. They want to move the entire symphony orchestra home for live performance! Therefore, they often go to the two halls to listen to live performances. Their overall volume control is always correct than those who rarely listen to live performances. If you have a string instrument, a wind instrument or a keyboard instrument in your home, you may use them to adjust the volume and adjust the volume appropriately so that the performance of the instrument played by the listening sound is almost the same as that of the actual instrument. Only when your stereo is called Hi-Fi.

Volume control is an art, the volume is large enough to affect the sound of the whole system. Why is the sound so bad? There are actually many reasons for this problem, and it is because there are so many. If you ca n’t figure it out yourself, I think someone else will find it harder to find out why. The reason why the sound is not good may be that the quality of the equipment you bought is not good, so it is not good; it may also be due to improper matching, so it is not good; of course, it is more likely that the speakers are not positioned correctly, so it is not good ... In short, unpleasantness is definitely a fact, and it must also have its unpleasant factors. Here, I want to put aside the others. It is easy to ignore the reasons why two ordinary people can easily ignore them, and I will not think about the reasons carefully. Perhaps, the reason why the house audio is not good is so simple, it is clearly placed in front of you, but you ignore it when listening to the sound every day, and desperately drilled into the horns. What are these two reasons? In fact, it is a big reason, that is, "Is your volume too loud?" After this big reason, it will turn into two small reasons: the speaker can not load too much volume; the space can not be loaded too much Volume.

The volume is turned up too loudly without realizing it. Most people have a misconception that as long as they are audio equipment, they want to be as loud as possible, and audio equipment should be able to sing well regardless of the loudness. In fact, audio equipment has its limits at the maximum and minimum sounds. In terms of electronics, the amplifier should be the original amplification of the signal obtained from the sound source without distortion, and The speaker is a kind of audio electric power signal in the audible range, which is converted into audible sound with a sufficient sound pressure level through a transducer (speaker unit). In order to select a good speaker correctly, you must first understand the properties of the sound signal, and then require the speaker to restore the audio electrical signal to a realistic and natural sound. Therefore, adjusting the volume appropriately so that most of the music played is an undistorted signal is a necessary condition for you to hear beautiful sounds. Therefore, the correct volume adjustment is very important, and it is definitely not possible to open more and more quietly. Why can't the volume be turned too loud? There are two reasons: one is that the amplifier and the speaker may not be able to withstand that loud sound, and serious distortion occurs, that is, the input signal we have said is cut; the second is that the listening space cannot bear so loud. The distortion of the amplifier is easy to understand, because it is not weak enough, but it has to exhaust all the power of feeding, and of course it is paralyzed there. As for the speakers, this is what I want to say. Generally, the power (or the volume of sound) that each speaker unit can withstand has its limitations. If it is within its capability, it can emit very low distortion and pleasant sound. However, once the volume exceeds its own load, it will produce severe distortion. As soon as the speaker unit is distorted, the sound will be harsh and unpleasant.

The speaker has a distortion limit and cannot be turned too loud. Here are a few examples to prove: First, if the sound is unpleasant and harsh, the volume is turned down, usually it is no longer unpleasant; Second, the general mini bedside sound, if you listen at a certain volume I often find that it sounds better than my own big set of sound! Of course, the sound is completely distorted after driving loudly. Third, if your car's sound insulation is not bad, when you listen to music at a moderate volume in the car, it often has a good sound performance. From the several examples available in daily life above, the importance of "appropriate volume" can be fully verified. It is a pity that most people often overestimate their own sound group combination, thinking that the small speakers bought at such an expensive price can only say that they can emit a very large volume. In fact, no matter how much money you spend to buy a speaker, a small speaker is a small speaker, and the volume it can emit has its limits. Even if your speaker unit is better than normal, it is just a little more able to bear the volume.

Use tenor and violin to test the volume. In the end, how to use the speakers correctly, so that they emit the appropriate volume without distortion? It's simple, just listen with your ears. Here I propose two kinds of sounds to test, one is the human voice and the other is the violin sound. Let's talk about vocals first, vocals are the most difficult instruments to perform, and the biggest test for general speaker units, especially tenor and soprano. Please listen to a tenor record (preferably Pavalotti, whose vocal energy is the most destructive). You can only turn the volume up until the tenor sings to a strong place. ". If it starts to feel unpleasant, it has already exceeded the load of the speaker. How loud will the volume of the line from the speaker sound? I do n’t know, some speakers can sing louder, while others can only sing softer. In the end you may suddenly find out, why can't my speaker sing so low? It started to sound awkward again. Do not doubt that the speaker unit is not superman, it cannot be driven without limit without distortion. How serious is the distortion of the speaker unit when it exceeds the load? If it is not an engineer, we may not know, because the speaker's narrative book will never list the distortion number of the speaker. It is because the amplifier has very low distortion, so even if the distortion number is listed, everyone will not pay attention to it. After the vocals have been tried, let's try again with the violin. There is no need to use a concerto, just a violin sonata. Only a violin and a piano can be heard clearly. It should be noted that when the violin sound begins to tighten, scratch, and become sharp, there is the limit. At this time, the volume should be reduced a little, until the violin sound does not sound tight, and the sweet sound can Until it appears, there is the most appropriate volume.
