摘要:
An analysis is made of the problem of intelligence pick‐up from anatomical vibration. Methods for measuring the actual and effective response‐frequency characteristics of the throat are described. Measurements on the variation of effective response among different subjects are discussed in connection with the concept of “oral efficiency.” Design and performance data are given for several magnetic throat microphones of relatively high sensitivity.
