Effects of Impulsive Interference upon A-M Voice Communication
J. C. R. Licklider, S. J. Goffard · The Journal of the Acoustical Society of America · 1947
The degree to which noise impairs the intelligibility of speech depends upon the characteristics of the noise. In this paper, which is concerned with electrical interference and radio communication, the questions are: (1) “what characteristics of the noise determine the degree of impairment,” and (2) “what are the functional relations between intelligibility and the important characteristics of the noise?” Answers to these questions were obtained with the aid of articulation tests, conducted with a typical amplitude-modulation system and with a variety of electrical interferences.
