§40 声场中的某些基本量一个有声音存在的空间,称为声场。我们主观上用耳听音,在人耳特性条件下,对声音大小的感觉是响度和力度。在客观上空气压强受到声波的干扰后,产生的是声压和声强。这说明人耳主观感受和客观上的物理量是不同的,但是主观感受的响度和力度是客观声压和声强在我们听觉上的反应。这些基本量都与发音体的振幅有关,振幅越大,
§40 sound field in some of the basic amount of a space where there is sound, called the sound field. We subjectively listen to the ear, in the ear conditions, the size of the sound sense of loudness and intensity. Objectively speaking, the air pressure is disturbed by sound waves, resulting in sound pressure and sound intensity. This shows that people’s subjective and objective physical quantities are different, but the loudness and intensity of subjective feelings are objective responses to the sound pressure and sound intensity in our hearing. These basic quantities are related to the amplitude of the sounding body, the greater the amplitude,
