Analysis of Noise-Related Auditory and Associated Health Problems in the U.S. Population (1971-1975) - Volume 2
March 1, 1982

The First National Health and Nutrition Examination Survey (NHANES I) was designed to characterize the overall health and nutritional status of the U.S. civilian noninstitutionalized population aged 1-74 years and to permit examination of the prevalence of specific health conditions on a subsample of adults aged 25-74 years. Analyses presented in this report are based on the national probability subsample of 6913 adults aged 25-74 years who were administered an audiometric test as well as detailed questionnaires and physics: examinations dealing with hypertension and a variety of other health conditions. Detailed occupational descriptions were used in the present study to estimate approximate eight-hour noise levels for the sample of 3942 adults aged 25-74 years in the workforce. Among the major findings: 1. Hearing impairment is a widespread health problem in the United States; 2. Occupational noise exposure was identified as a major risk factor associated with the prevalence of hearing impairment among men; 3. Occupational noise exposure was not significantly related to hearing sensitivity among working women; 4. Occupational noise exposure was found to have a weak, but nevertheless significant association with hypertension for both men and women; 5. Among men, occupational noise exposure was associated with overall physical health, whereas among women, it was associated with only overall psychological health; and 6. No conclusive relationships were found between occupational noise exposure and the remaining indicators of specific health conditions.

A Basis for Limiting Noise Exposure for Hearing Conservation
July 1, 1973

A compilation of data is provided, with references to published work, which represents the present state of knowledge concerning the effects of continuous and impulsive noise on hearing. The danger to the ear of both occupational and non-occupational human exposure to noise is considered. Data are included or cited which enable quantitative predictions to be made of the risk to hearing in the American population due to noise exposure in any working or living context. Recommendations are made concerning the need to obtain more definitive data. Relevant aspects of noise measurement, the physiology of hearing, and theories explaining the effects of noise on the ear are discussed in appendices to the main report. This report deals solely with the effects of noise on hearing; other physiological or psychological effects of noise are not considered in the present document.

Economic and Social Impact of Occupational Noise Exposure Regulations
September 1, 1976

This report elaborates on the costs and benefits associated with alternative occupational noise exposure regulations. The limitations of cost/benefit analysis for social decision-making are enunciated. The impact of various regulatory alternatives for 85 dBA and 90 dBA criteria are analyzed.

Impact of Noise on People
May 1, 1977

Aviation noise significantly impacts approximately six million people in urban areas. In an effort to explain the impact of noise on these citizens, the Federal Aviation Administration (FAA) presents this brochure. Included are aircraft noise indices, information on human response to noise, and criteria for land use controls. Additionally, hearing damage and occupational health standards for noise are described. FAA presents this information in an effort to enhance public understanding of the impact of noise on people and to answer many questions that typically arise.

Noise - How Much is Too Much?
May 20, 1975

Henning E. von Gierke contends that enough is known about the effects of noise on people to produce guidelines for maximum noise levels. Adopted by the Environmental Protection Ageny, these guidelines are designed to protect the public with an adequate margin of safety against hearing loss from occupational and environmental noise exposures and against interference with speech or other activities indoors or outdoors in residential areas.

Noise Hazard Evaluation - Sound Level Data of Noise Sources
January 1, 1975

This technical guide was developed as an aid simplification of the noise hazard assessment element of the installation hearing conservation program. Part I of the technical guide provides the reader with basic information necessary for the conduct of a routine occupational noise hazard evaluation, while part II provides additional information and guidance concerning typical personnel exposures to military noise sources.

Noise in America: Extent of the Noise Problem
September 1, 1981

The number of Americans exposed to various levels of occupational and environmental noise is estimated. Estimates are made for 11 categories of noise producers (e.g., traffic, aircraft, construction) using the Ldn or Leq(24) metrics. The assumptions in the models used, including , including demographic projections, are made explicit for all estimates. Estimates for combined exposures to traffic and other community noise sources are also made, as well as indoor noise exposures from home equipment like fans and clothes washers. According to the estimates, 1.5 million people are exposed to outdoor noise levels (from a11 sources) of over 75 Ldn, and over 90 million, to levels over 58 Ldn. Over 9 million people are exposed to occupational noise in excess of 80 dB (Leq(24)).

Occupational Hearing Conservation

Prediction of NIPTS Due to Continuous Noise Exposure
July 1, 1973

In support of the main document, "A Basis for Limiting Noise Exposure for Hearing Conservation," this report compares the relationship of noise exposure to Noise Induced Permanent Threshold Shift (NIPTS) as predicted by the currently available works of Passchier-Vermeer, Robinson, Baughn and Kryter, and the yet unpublished work of the National Institute of Occupational Safety and Health. The works of Passchier-Vermeer, Robinson, and Baughn are selected since these are the only works that completely predict the relationship between NIPTS and noise exposure for various audiometric frequencies, sound pressure levels and population percentiles. The predictions of these three methodologies are averaged in order to provide one single relationship between continuous noise exposure and NIPTS. This relationship is presented in various ways so that the effect of noise exposure on hearing can be viewed in more than one way. Discussion concerning the type of frequency weighting, the equal energy rule, and long duration exposures is also provided.

State and Municipal Non-Occupational Noise Programs
December 31, 1971

This document is a report on state and municipal government non-occupational noise abatement and control programs prepared from information obtained in response to a questionnaire disseminated by the Environmental Protection Agency (EPA). The questionnaire and a letter of inquiry were part of a study to establish the national need for legislation and research concerning noise abatement and control. They were forwarded by the EPA Administrator to the governors of each state (including Guam, Puerto Rico, the Virgin Islands) and the mayors of the 153 cities having populations, as of 1970, of 100,000 or more. The questionnaire requested information concerning the level and scope of existing and planned noise abatement and control programs. It furthermore solicited opinions on what additional support programs could be developed by the Federal government. Described herein are the replies of 114 mayors and of 41 governors.
