Show Abstract
Much of the literature on community noise concerns attempts to correlate measured characteristics of noise with reaction to that noise evaluated from personal surveys. The purpose of this special session is to focus instead on why people react as they do. The special concerns are identification, examination, and measurement of the subjective variables which influence human reaction to sound. Emphasis is on annoyance and the underlying factors to which people react. The three invited papers present methods, viewpoints, and evidence from the points of view of noise control, speech communications, and psychological acoustics. Particularly intriguing is the idea that annoyance is the inverse of preference.

Show Abstract
Relating noise‐induced annoyance to acoustic quantities has proved to be a frustrating undertaking. In several decades of pursuit of formal means for quantifying adverse attitudes of individuals and groups toward noise exposure, the successes have been relatively narrow in scope, and are the exception rather than the rule. One is as hard pressed to predict in precise terms how acceptable a new noise source will be to a community as to characterize the absolute acceptability to individuals of degraded speech quality. Many are inclined to attribute the meager success in predicting annoyance from acoustic quantities to problems of measurement—either physical or social. The viewpoint presented in this paper is that the problems are more fundamentally those of theory and analysis, and that substantial progress in this field is unlikely to result from further applications of old approaches and methods.

Show Abstract
Characterizing the subjective effects of sound is similar to the problems of characterizing sound itself. Since both are functions of several variables, the values of each variable must be found to evaluate the significance of changes. The wave motion model of sound enables us to express the variability in the nature of sound as a function of its independent variables with great mathematical precision. Similar accuracy in measuring the perception of sound cannot be achieved without a model that expresses the variables of perception and their interrelationships. Methods for studying the variables of perception have been, and are being, developed. The application of these techniques to subjective judgments of sound is currently producing information about the variables of sound perception and their relation to the variables of sound itself in the realm of speech. From this information, a model for combining the variables to predict speech preference is being derived. These methods have not been applied to the problem of noise perception. However, if one considers annoyance as the opposite of preference, the techniques are directly applicable to the problem of characterizing the perception of noise.

Show Abstract
The perceived sound quality of any auditory stimulus (music, speech, noise) may be expressed in terms of overall evaluations as well as in terms of specific perceptual qualities. Examples of the former are variables as pleasantness, annoyance, and fidelity, and of the latter perceptual variables as loudness, clarity, sharpness, etc. Studying the relations between overall evaluations and separate variables and their respective relations to the stimulus characteristics may increase the understanding of factors influencing perceived sound quality. The associated methodological problems will be illustrated by examples from research on perceived sound quality of sound‐reproducing systems [A. Gabrielsson and H. Sjǒgren, J. Acoust. Soc. Am. 65, 1019–1033 (1979)]. Some possible parallels, as well as dissimilarities, between this research and research on noise‐induced annoyance will be discussed.
