A Method for the Quantitative Measurement of Wind-Noise Sensitivity in Microphones
A spring-hinge pendulum may be used to carry a microphone noiselessly through the still air of an anechoic chamber. The noise generated by the flow of air past the microphone is easily measured and analyzed. Velocities of the order of 15-20 mph are obtainable with the pendulum, whose period is about 3 seconds. The output of the microphone may be recorded with a high-speed recorder. With the addition of a variable bandpass filter at the input to the recorder, a noise spectroanalysis may be accomplished. Wind-noise spectra of an RCA 77D in three directional characteristic settings are presented and commented upon.
