Abstract:

Current techniques of microphone calibration are not readily adapted for use in the field and do not produce data on both frequency and phase characteristics. A new technique was investigated for calibrating microphones using a pressure impulse, which will produce calibration of both amplitude and phase and will be adaptable to field use.
