The limiting sound pressure is a characteristic value of microphones. It is the sound pressure of a 1 kHz tone that a microphone can process at a distance of 1 m with a certain distortion factor
. The distortion factor is specified when the limiting sound pressure is given.Moving coil micro phones are superior to other microphones with respect to the limiting sound pressure level.
Compared to condenser microphones, a moving-coil microphone can handle about 30 dB more sound pressure without distortion. The limiting sound pressure level of condenser microphones is around 140 dB.
