音響檢驗(yàn)的難點(diǎn)在于我們聽到的聲音看不見(在示波器上也是雜亂無章的波形)，摸不著，并且每個人的聽力各有差異。從用戶的角度，個人有個人的喜好，有人特別討厭功放的滋滋聲，有人又特別討厭低音的嗡嗡聲，這些都增加檢驗(yàn)的難度。我們須長期訓(xùn)練，練就明銳的聽覺，積累經(jīng)驗(yàn)，才能判別各類產(chǎn)品缺陷。
The difficulty of acoustic inspection is that the sound we hear is invisible (chaotic waveform on the oscilloscope) and can not be touched, and everyone's hearing is different. From the user's point of view, some people have their own preferences, some people especially hate the noise of the power amplifier, and some people especially hate the buzz of the bass. All these increase the difficulty of the test. We need long-term training, sharpening our hearing and accumulating experience to identify various product defects.
