This brochure which presents aircraft noise indices, information on human response to noise and criteria for land use controls, also describes hearing damage and occupational health standards for noise. Measurable physical characteristics (intensity, frequency content, sound pressure) which determine how people perceive loudness are discussed, and the factors which determine emotional response are listed. Comparative noise levels showing typical decibel values encountered in daily life and industry are tabulated. A table is presented which summarizes the relationship between various indicators of community annoyance and several cumulative noise indices. It also illustrates the point that a valid indicator of noise impact is the changing percentage of population associated with a given response. The noise levels requisite to protect public health and welfare with an adequate margin of safety are summarized, and important facts related to temporary auditory threshold shifts (temporary hearing loss) are noted.
