Determination of Microphone Performance
F. L. Hopper, Frank F. Romanow · Journal of the Society of Motion Picture Engineers · 1941
Methods of determining the performance characteristics of microphones by acoustic measurements are described. Work Factors involving the accuracy of the methods are discussed. The correlation between a microphone's performance as determined by acoustic measurement and by listening tests is reported. Application of both types of test to a studio type of cardioid microphone is given as an example.
