MICROPHONE, HEAD CONTACT M-123( )/U.
Abstract
This report describes work performed during the quarterly period beginning September 1, 1964, and ending November 30, 1964, toward development of a practical head contact microphone. Contact location research was expanded to include all head regions of interest to this program. To insure generality, measurements were taken with ten talkers at various head locations. Spectral analysis and listening tests were performed, and results are described herein. A statistical analysis of level differences as a function of location and talker is given. Experiments were performed with the aim of design of a practical transducer. These included measurements of noise cancellation properties and mechanical impedance requirements. (Author)
