"Sound level" is the sound pressure level in dB SPL or the sound intensity level in dB SIL. For Pa say, Pascal. This is the size for the pressure p = force F by area A. The reference sound pressure is p0 = 20 µPa = 2×10−5 Pa. The reference sound intensity is I0 = ...

The diaphragm of the microphone responds to changes in atmospheric pressure caused by sound waves. that's why the instrument is usually mentioned as a instantaneous sound pressure Level (SPL) Meter. This movement of the diaphragm, i.e. the instantaneous sound pressure deviation (pascal Pa), is...

When discussing acoustic sound levels, 0dB SPL (sound pressure level) is the typical threshold of human hearing at 1kHz, and relates to a sound pressure of 20 microPascals. 1 Pascal of sound pressure is equivalent to an SPL of 94dB, and 1 atmosphere of pressure is around 194dB SPL.Relate...
In the data sheets the sensitivity always applies to the frequency1 kHz, unless otherwise noted. Reference: 74 dB-SPL ≡ 1 dyne/cm2= 0.1 pascal = 1 µbar Threshold of hearing: 0 dBSPL ≡ 0.0002 dyn/cm2= 0.00002 Pa Fill out the respective box and click the 'calculate' bar below. ...
那么音乐制作之后的音源也能有这么大的动态范围或者适合在120dB最大SPL的情况下回放么？
