"A series of judgment tests were conducted to investigate subjective judgments of single, modulated and multiple tones plus noise. The subjects were asked to judge which of two sounds, tones plus noise or noise alone, was noisier (or in some cases louder). Stimuli included both broadband and octave band noises together with single tones at 250, 500, 1000, 2000, 4000 Hz. Amplitude and frequency-modulated tones of 500 and 2000 Hz were also employed. Multiple tone stimuli included 2 and 5 tone complexes with overall frequency spacings of 1/10, 1/3, 1, 4/3 and 2 octaves. Analysis of the judgment results were made using calculated perceived noise level and pure tone correction procedures suggested both by Little, and by Kryter and Pearsons. In general, the pure tone corrections were necessary, the exception being situations in which the pure tone is added to an octave band of noise. In one test series; however, the pure tone adjustment appears to overcorrect in all conditions. The effect of the instruction set was marked. The addition of a pure tone to noise had less effect on judgments of loudness and more effect on judgments of noisiness. The average difference was 5 dB. Modulated tones showed little difference from those of unmodulated tones, except at low modulation rates which produced annoying beats. For multiple tones there appeared to be no difference in people's assessment of harmonic and non-harmonically related tone complexes. Although the noisiness increases somewhat with increase in number of tones, this effect does not require modification of the present pure tone correction methods."--Summary.

The Effects of Noise on Man covers the techniques for the evaluation of environmental noise in terms of its effects on human. The book provides the fundamental definitions of sound, its measurement, and concepts of the basic functioning, and the attributes of the auditory system. The text also presents along with their experimental basis, procedures for estimating from physical measures of noise its effects on man's auditory system and speech communications. The last part of the book is devoted to man's nonauditory system responses and includes information about the effects of noise on work performance, sleep, feelings of pain, vision, and blood circulation.
