Initial Study on the Effects of Transformer and Transmission Line Noise on People. Volume 3. Community Reaction. Final Report

摘要

A social survey intended to assess reactions to exposure to noise emissions of overhead electric power transmission lines and power transformers was conducted in Southern California. A structured questionnaire similar in approach and content to a recent nationwide urban noise survey (Fidell, 1978) was administered by personal interview to a purposive sample of about 400 people residing at 17 sites along power line rights-of-way and in neighborhoods adjacent to transformer substations in urban areas. Estimates of the proportion of the American population exposed to noise of different levels from power lines and transformers were developed by analyses of several information sources. Acoustic measurements were made at all interviewing sites to assess the contributions of these low level electrical noise sources to overall background noise environments. (ERA citation 05:020588)
