Microphone: measures pressure or displacement?
i think some microphones are better thought of as displacement measurers instead of pressure measurers. is this true? - Omegatron 20:08, Jul 16, 2004 (UTC)
- I can't see what the objective difference between these alternatives would be, given that the displacement e.g. of some membrane is directly caused by the pressure of a sound wave. Therefore, it seems to me that the question is meaningless. RPaschotta 10:49, 21 Nov 2004 (UTC)
Sound pressure amplitudes
When sound pressures are specified, one should be more clear about their definition: is it the peak pressure (i.e., the amplitude of a sinusoidal signal), or rather some rms (root-mean-square) value? This applies e.g. to the reference sound pressure specified in the article. Can anybody help? RPaschotta 10:49, 21 Nov 2004 (UTC)
