Judging the sound effect is good or bad, basically depends on everyone's ears. Due to different personal preferences, there is no clear criterion for judging the sound quality so far, and it can only represent the sound brand according to many reflected data and word of mouth.
Judging the sound effect is good or bad, basically depends on everyone's ears. Due to different personal preferences, there is no clear criterion for judging the sound quality so far, and it can only represent the sound brand according to many reflected data and word of mouth. Whether listening to music, singing karaoke or watching movies, in fact, the quality of the sound mainly depends on the following factors:
1. Signal source
We know that the function of the power amplifier is to output the weak level signal source amplifier to the speaker, and then the sound of various frequencies is emitted by the vibration frequency of the speaker unit in the speaker, that is, the high, medium and bass we hear. If the signal source has noise (distortion) or some signal components are lost after compression, the noise will be enlarged even more after amplification by power amplifier, and the lost components will not be released. Therefore, it is also critical that the sound source used in our evaluation of sound is good or bad.
Reasonable matching of sound system equipment can give full play to the advantages of the brand, that is to say, the power amplifier should have high signal-to-noise ratio, wide effective frequency response and low distortion, the sound box should have wide effective frequency and flat frequency response curve, and the sound with frequency response reaching 20Hz --- 20KHz can be said to be very good. At ordinary times, it is difficult to distinguish signals above 20Hz in our normal ears, so it is not necessary to pursue some ultra-high frequencies that we cannot hear. Only when the frequency response width curve is flat can the original sound be reproduced realistically.
In terms of power, it depends on the size of the area used. The two should be proportional. If the area is too small and the power is too large, a large sound pressure will cause too many reflected sounds, making the timbre turbid, otherwise the sound pressure is not enough. The power of the power amplifier is 20% to 50% larger than that of the sound box in impedance matching, so that the bass will be strong and strong, the middle and high levels will be clearer, and the sound pressure will not be distorted so easily.
(2) Users themselves
Some people buy stereos for decoration, some to enjoy music, and some to show off. The popular point is to see others buy a set of brand stereos and buy one as soon as possible. They do not understand the advantages and disadvantages of each brand at all. What brand of stereos are more suitable for listening to music, what brand of stereos are more suitable for watching movies, and what brand of stereos have advantages in singing. Therefore, before buying, you must first know which one you usually focus on and choose a set of sound that suits your needs. If a person can't hear the high and low sounds of the stereo clearly, it's impossible to hear what good sound quality is.
In addition, in addition to listening, but also to use. After the sound is installed, the sound mixer will use technical means to adjust the ratio of each equipment to a reasonable state. If one day you accidentally move some buttons with curiosity, the effect can be imagined. This is not to say that you have to understand technology to buy audio. Just like we drive, we must at least understand the functions of various switches, buttons and knobs in order to give full play to the performance and safety of this car.
3. Use environment
Everyone knows that when there are no people in an empty room, the echo is especially loud when clapping and speaking. This is because there is no sound-absorbing material on six sides of the room or the sound-absorbing is not enough, which is caused by reflected sound. The same is true of sound. If the environment is not good, the sound will not be pleasant to listen to, especially if the sound is slightly loud, it will be very turbid and harsh. Of course, some people will say that it is impossible to make a professional audition room at home. In fact, as long as you put a little effort into hanging an embroidered picture on a large wall, it is both beautiful and sound-absorbing. Another example is to hang thicker cotton curtains on glass windows or to spread carpets on the ground. The effect will be unexpected. The positioning of the sound box will also affect the sound quality, and the sound field can also determine the sound quality, just like if you drive a BMW into a rice field, you may not be able to beat a tractor.
