Accidental damage and decalibration prevented. Linearity, sensitivity, and frequency response of microphone measured with commercial sound generator modified so placed directly over or under microphone. Artificial voice connected to oscillator and measuring amplifier. Requisite frequencies and sound pressures applied to microphone, and microphone output recorded. New calibration method used on aircraft and wind-tunnel microphones.
