Noise, that undesirable portion of the ever-present sounds of our environment, has until the last decade, been considered as an unavoidable by-product of our rapid population growth and its accompanying mechanization. As awareness of adverse health effects from noise exposure grew, the Federal government, as protector of the public health and welfare, took the initial steps to control noise pollution. Federal legislation, beginning with the Clean Air Amendments of 1970, has been promulgated to control major offenders and to assist State and local governments in their endeavors to provide the public with an environment free from harmful noise levels. This paper first discusses sound and noise, the methods for describing and quantifying noise, and levels needed for protection. Secondly, control and abatement efforts are discussed with emphasis on legislated goals, the role of the Environmental Protection Agency, and State and local actions.

This report uses a computer program to study the effects of the following parameters on noise exposure forecast contours: 1. Aircraft mix, 2. Aircraft track, 3. Number of operations, 4. Time of day and 5. Aircraft thrust.

I challenge quiet regulations within my own community, the Claremont University Consortium, by hosting two Silent Discos in culturally and explicitly quiet locations: the Honnold Mudd Library and the James Turrell Skyspace at Pomona College. Attempting to demonstrate Silent Disco’s ability to sonically adapt to quietly marked areas I recorded the sounds generated by these events and later amplified them in these culturally quiet locations. These Silent Discos embrace the given environment and sound limitations, while simultaneously accepting the popular modes of musical listening. By performing Silent Discos in the James Turrell Skyspace at Pomona College and the Honnold Mudd Library, I give the power to each individual to reduce noise pollution, while collectively listening to the same music as a group.

M.Sc. / The Strubensvalley area is an up market area with numerous shopping centres and trendy dwellings. A major road, namely Hendrik Potgieter Road (M47), feeding between Johannesburg and North West/Botswana, runs through the suburb. Residents of Strubensvalley are in their concern about this road: the noise pollution which impacts negatively on their lives. This research investigates the traffic noise and the impact it has on the population of Strubensvalley.The selected study area was delimited by drawing a circle with a radius of four kilometers around the middle point, it being at the intersection of Hendrik Potgieter Road and Krugerrand Road. Clearwater Mall and Wilgeheuwel Retail Crossing shopping centre are the two large features on the circumference of the study area. A calibrated sound level meter was used to measure the traffic noise at 18 different measuring points within the study area. Measurements were taken during the day (6am to 10pm) and at night (10pm-6am) in order to establish the noise impact caused by the peak flow and non-peak flow of traffic in the suburb. A 30-item noise -health-related questionnaire was used to establish the impact of traffic noise on the respondents. A hundred randomly -chosen participants within the study area were interviewed on a door-to-door basis. On completion of this research, it was established that the people interviewed were generally annoyed by the traffic noise in Hendrik Potgieter Road. The majority of the participants complained about the annoyance and interference factor caused by traffic noise in that it affected them in activities (e.g. napping during the day).

Thesis (MTech (Environmental Health))--Cape Peninsula University of Technology, 2006 / Airport operations have become a major source of concern due to aircraft nOIse, particularly in areas close to airports and aircraft flight tracks. Public opposition to aircraft noise is a threat to the continued growth of civil aviation in South Africa. This study investigated the psychological effects of aircraft noise on residents and school activities at a neighbourhood close to the airport, particularly the area located under the flight tracks or adjacent to the landing and departure pattern of aircraft. Bishop Lavis was chosen as the experimental area and Kensington, about 17km away from the airport, was chosen as a control area. Questionnaires coupled with oral interviews and observations were used to gather information. The findings are focused on annoyance and disturbance. The study revealed that noise exposure caused annoyance, activity disturbance and some mild effects on school results, when compared with the control area. Disturbances were experienced in some activities that need concentration. Aircraft noise also caused communication interference, sleep deprivation and affected the teaching process. The community at the experimental area indicated some non-acoustical effects, such as fear of aircraft crashing over their homes but they indicated no willingness to leave the area. As such, it becomes essential when locating and designing airports to optimise flight paths in a way to reduce noise exposure to nearby communities. Recommendations for mitigation of noise exposure are proposed, which include operational procedure, banning chapter I and 2 aircraft, restricting night flights, proper land use planning and enforcing international environmental regulations.

Este projeto de pesquisa pretende contribuir para o tema da acústica do ambiente externo às igrejas, fornecendo um panorama em linhas gerais da natureza e magnitude das ocorrências sonoras externas às igrejas de uma área de amostragem constituída por 12 igrejas situadas em região urbana na cidade de São Paulo. A partir de dados coletados do entorno, das tipologias, dos resultados das medições sonoras e da aplicação de questionários, a pesquisa pretende compreender melhor as causas e os efeitos das fontes de ruído na vizinhança, bem como a de recomendar meios de prevenção dos problemas, tanto nos projetos de novas edificações como na escolha e adaptação de edificações existentes para a finalidade do culto religioso. / This research project aims to contribute to the acoustic theme of the external environment to the churches, providing an overview in general terms the nature and magnitude of external sound events to the churches of a sampling area consists of 12 churches located in urban areas in the city of São Paulo. The data collected from the field survey, made available around the information and typology of the churches and the comparison of results of noise measurements,the research seeks to analyze the causes and effects of noise sources in the vicinity, as well as recommend means of preventing problems, both in the projects of new buildings in the choice and adaptation of existing buildings for the purpose of religious worship.
