Test method for sound quality

The audition test method is a common method for testing each sound segment of the audio, and we need to conduct an audition test for each sound segment of the bass, midrange and treble, so as to ensure that the sound can play a high-quality listening enjoyment. So, how to test the sound quality of the speaker?


Test method for sound quality


First, the bass part


The bass effect of the sound can be said to be a very important part of the overall sound quality, it is directly related to the shock effect of the fullness of the sound effect, the performance requirements of the bass unit are used for the sound, so we also carry out the following tests: put a glass of water next to the sound, the sound with good bass effect can cause the vibration of the water cup, who is also rippling in the water cup, the better the bass effect, the more obvious the effect, and the longer the time. The more realistic the weapon sound and explosion sound effect, the better the shock effect.


Second, the alto part


For most audio products, it is difficult to distinguish the sound quality of the midrange. His main function is to generate realism, and the test for the midrange part is to watch a multi-channel movie (i.e., the kind with two voices played together).


3. The treble part


The treble effect of the sound is generally very intuitive. For example, singing and some special electronic sound effects, and even some extreme sounds that are beyond hearing range. How to do this test is by using some treble vocals.
