Vibration Sensitivity Measurements on Subminiature Condenser Microphones

Authors: Killion, Mead C.

Abstract

A recently introduced series of subminiature electret-condenser microphones has brought to light an interesting problem: Their vibration sensitivity is so low that an accurate measurement becomes difficult. Not only must the microphone be isolated from the sound pressure generated by the vibration driver, but simply vibrating the microphone creates a -radiation pressure- which must be taken into account. Measurement techniques are described which permit the accurate measurement of vibration sensitivity even when the vibration sensitivity of the microphone is extremely low.
