The term "sound quality" is generally a general interpretation of the quality of sound. However, in audio technology, it contains three aspects: (1) the pitch of the sound, that is, the intensity and amplitude of the audio; (2) the pitch of the sound, that is, the frequency of the audio or the number of changes per second; (3) the sound of the sound, that is, the audio Overtone or harmonic components. Judging whether the sound quality of an audio product is good or bad, it is mainly to measure whether the above three aspects of the sound reach a certain level. Liu Hansheng, a well-known audio master in Taiwan, once wrote an article to the general enthusiasts about "What is the ear, what is good?", through his own experience of more than 20 years of "reading countless": although everyone's The taste of the listener will be very different, but as long as you master the following six words of "three wrongs and three pairs", you can purchase the sound exactly according to your listening experience, without having to care about the advice of others. First, the sound is sharp is wrong Does the sound of the violin sound sharp and harsh? Whether you have experience listening to violin or not, I want to tell you, no. If you don't believe it, you can go to the restaurant in the restaurant and listen to the violin, piano and cello that are often there. Will they be harsh? I promise not. Does the vocal sounds harsh? Absolutely not! But why does the store have a feeling of tearing the ears when the soprano or tenor is released? That is the distortion! How can the vocals be so beautiful, how can it be harsh? Don't worry about what others say, as long as the vocals will be harsh, it won't be right. Vocals and violins can't be harsh. Will other cellos, flutes, and wooden tubes be pierced? Of course not! So, you have to say with confidence and confidence: They are not right, they are too harsh! Second, the sound is shrinking is wrong "Retracted" can be used in Minnan dialect. In other words, the sound can not be opened, always huddled together, not open and wide, these are the performance of the sound shrinking. If you go to the concert hall to listen to the concert, the sound of the orchestra will not be transmitted in the stage. Is this concert hall design right? Of course not! The same reason, the function of the speaker and amplifier is to send the music. Every corner of the room. If the sound you hear is shrunk in the speaker, or the sound is always squeezed into the two speakers, you don't have to doubt, there must be a problem. Of course, the problematic voice does not buy. Third, as long as the sound is dead is wrong Have you heard anyone playing music that is dying and inactive? If there is such a performer or orchestra, it is impossible for a record company to invite them to record. The music played by people who can record must be full of energy and full of life. Whether he is playing the slow board, or they are whispering in the ensemble, the music must be full of strength and tension, there must be active pulsation in the music rather than dead. If the sound you hear has always been lively and dead, then you must not buy such a sound, they must have a problem. You have the power to buy audio equipment that sounds full of life and sounds comfortable. As for why the sound is going to die? You don't have to worry about this, leaving these questions to the store to study. Fourth, as long as the sound is sweet, it is right. Is the sound sweet? Is it as sweet as red bean soup or mung bean soup? Is it as sweet as ice cream? Of course not! The so-called sweet-sounded string is the kind of shiny that sounds like water! For sweet, if the sound you hear is dry and dry, it is wrong again. In fact, the vocals are the same. If it sounds broken, then never buy it. 5. As long as the sound is full, it is right. The thinness of the sound indicates that the middle and low frequency bands are not enough, so they lose balance. It is like a thin bamboo raft, this is wrong. The really good sound should be full and full of energy. Whether it is the intermediate frequency or the low frequency, it must be strong and full, not virtual and thin. If the sound is thin, it means that the sound is very thin, and you can't hear a lot of details or overtones. In short, no matter what kind of instrument, the sound they send out is like a person who is full of food (of course not the brain full of fat) is very healthy. 6. As long as the sound is loose, it is right. A tight voice can make people nervous for a long time, and a loose voice can make people relax for a long time. The really good sound should be soft and energetic. Please note that what I call loose is not as porous as a sponge. It is like a spring that will slowly bounce off the loose. If the sound is hard and inflexible or loose, there is no power. As long as you can remember the three mistakes and three pairs of mouths I mentioned above, no matter where you go, just listen to what CD, you can tell yourself with confidence: this voice is wrong, I have to choose another. In this way, you don't have to go to an expert, and you don't have to envy others' golden ears. In fact, you are an expert who takes music as the standard and listens to it.
