学过声现象一章后，我们了解到响度是人们主观上感觉到的声音的强弱．事实上，响度是跟声强有关的，人耳能听到的最小声强是0分贝，能忍受的最大声强约为120分贝．但是，不同频率的声音，即使声强相同，响度也是不一致的，因此，不同频率的声音，听阈也不同．人耳对于频率为10 After learning a chapter on the phenomenon of oversight, we learned that loudness is the strength of people’s subjectively perceived sound. In fact, the loudness is related to the intensity of the sound. The minimum sound intensity the human ear can hear is 0 dB. The maximum sound intensity that can be tolerated is about 120 dB. However, the sounds of different frequencies do not have the same loudness even if the sound intensity is the same. Therefore, the sound thresholds of sounds with different frequencies are also different. Human ear for frequency 10
