The report attempts to account for some of the most prominent auditory characteristics in terms of physiological mechanisms. The first characteristic so analyzed is pitch as a function of sound frequency -- the classical subject of the theories of hearing. The following section is devoted to the effects of sound frequency and temporal stimulus pattern on the threshold of audibility. The threshold is defined in this context as the stimulus intensity that produces a 50 per cent probability of signal detection under constant experimental conditions. Further sections deal with masking, contrast, and critical band phenomena, and with loudness. All these sections are preceded by an elementary theory of sound stimulus and by a theory of sound transmission in the ear.
