Abstract : A device for measuring microphone sensitivity and droop by subjecting the microphone to a negative step function input and recording the microphone electrical response thereto. The microphone is surrounded by an inflated thin, flexible, expandable membrane. The membrane is ruptured resulting in an instantaneous reduction in air pressure on the microphone. It is this instantaneous reduction in air pressure that constitutes the negative step function input to the microphone. (Author)
