Health Effects Of Noise Pollution

Environmental Noise Pollution: Noise Mapping, Public Health and Policy addresses the key debates surrounding environmental noise pollution with a particular focus on the European Union. Environmental noise pollution is an emerging public policy and environmental concern and is considered to be one of the most important environmental stressors affecting public health throughout the world. This book examines environmental noise pollution, its health implications, the role of strategic noise mapping for problem assessment, major sources of environmental noise pollution, noise mitigation approaches, and related procedural and policy implications. Drawing on the authors' considerable research expertise in the area, the book is the first coherent work on this major environmental stressor, a new benchmark reference across disciplinary, policy and national boundaries. Highlights recent developments in the policy arena with particular focus on developments in the EU within the context of the European Noise Directive Explores the lessons emerging from nations within the EU and other jurisdictions attempting to legislate and mitigate against the harmful effects of noise pollution Covers the core theoretical concepts and principles surrounding the mechanics of noise pollution as well as the evidence-base linking noise with public health concerns

Environmental noise is defined as the noise emitted from sources such as road, rail and air traffic, industries, construction and public works, and the neighborhood. Noise has been ranked high among forms of pollutions, which include air pollution, radioactive waste pollution, water pollutions, etc. In recent years, noise has received considerable worldwide attention as a result of the many studies linking noise pollution to various health effects that include auditory as well non-auditory health effects. It should be noted here that the effect of noise is seldom catastrophic, and is often only transitory. However, its adverse effects can be cumulative with prolonged or repeated exposure. Noise with daily activities and it causes sleep disruption, masking of speech, reduction in performance and the inability to enjoy one's property or leisure time. It impairs the quality of life. In addition, several studies have linked extended exposure to high noise levels to cardiovascular diseases, including high blood pressure and irregular heartbeat. It has also been reported that high noise levels have an economic effects, especially tourism and real estate sectors, where it has been reported that the prices of houses tend to be higher in quite areas. There is also some evidence that noise can adversely affect general health and well-being in the same manner as chronic stress. Because of these factors, and the recent public awareness of the adverse effects of noise in the last few decades, many studies and noise monitoring programs have been established in various parts in the world. These studies and programs focus on measurements of perceived sound levels in communities, in the workplace (occupational noise), near airports and in public parks. A second area of research, which is getting more attention in recent years, focuses on assessing the effects of noise on individuals and communities, i.e. noise annoyance. This book discusses several topics that include driver style influence in the vehicle acoustic emissions in urban traffic; reaction to hybrid noise in communication; otoacoustic emissions by product distortion in metallurgical workers exposed to different doses of occupational noise; underwater noise pollution; and noise pollution in Zimbabwe.

The surprising science of hearing and the remarkable technologies that can help us hear better Our sense of hearing makes it easy to connect with the world and the people around us. The human system for processing sound is a biological marvel, an intricate assembly of delicate membranes, bones, receptor cells, and neurons. Yet many people take their ears for granted, abusing them with loud restaurants, rock concerts, and Q-tips. And then, eventually, most of us start to go deaf. Millions of Americans suffer from hearing loss. Faced with the cost and stigma of hearing aids, the natural human tendency is to do nothing and hope for the best, usually while pretending that nothing is wrong. In Volume Control, David Owen argues this inaction comes with a huge social cost. He demystifies the science of hearing while encouraging readers to get the treatment they need for hearing loss and protect the hearing they still have. Hearing aids are rapidly improving and becoming more versatile. Inexpensive high-tech substitutes are increasingly available, making it possible for more of us to boost our weakening ears without bankrupting ourselves. Relatively soon, physicians may be able to reverse losses that have always been considered irreversible. Even the insistent buzz of tinnitus may soon yield to relatively simple treatments and techniques. With wit and clarity, Owen explores the incredible possibilities of technologically assisted hearing. And he proves that ears, whether they're working or not, are endlessly interesting.

In the Occupational Safety and Health Act of 1970, Congress declared that its purpose was to assure, so far as possible, safe and healthful working conditions for every working man and woman and to preserve our human resources. In this Act, the National Institute for Occupational Safety and Health (NIOSH) is charged with recommending occupational safety and health standards and describing exposure concentrations that are safe for various periods of employment-including but not limited to concentrations at which no worker will suffer diminished health, functional capacity, or life expectancy as a result of his or her work experience. By means of criteria documents, NIOSH communicates these recommended standards to regulatory agencies (including the Occupational Safety and Health Administration [OSHA]) and to others in the occupational safety and health community. Criteria documents provide the scientific basis for new occupational safety and health standards. These documents generally contain a critical review of the scientific and technical information available on the prevalence of hazards, the existence of safety and health risks, and the adequacy of control methods. In addition to transmitting these documents to the Department of Labor, NIOSH also distributes them to health professionals in academic institutions, industry, organized labor, public interest groups, and other government agencies. In 1972, NIOSH published Criteria for a Recommended Standard: Occupational Exposure to Noise, which provided the basis for a recommended standard to reduce the risk of developing permanent hearing loss as a result of occupational noise exposure [NIOSH 1972]. NIOSH has now evaluated the latest scientific information and has revised some of its previous recommendations. The 1998 recommendations go beyond attempting to conserve hearing by focusing on preventing occupational noise-induced hearing loss (NIHL). This criteria document reevaluates and reaffirms the recommended exposure limit (REL) for occupational noise exposure established by the National Institute for Occupational Safety and Health (NIOSH) in 1972. The REL is 85 decibels, A-weighted, as an 8-hr time-weighted average (85 dBA as an 8-hr TWA). Exposures at or above this level are hazardous. By incorporating the 4000-Hz audiometric frequency into the definition of hearing impairment in the risk assessment, NIOSH has found an 8% excess risk of developing occupational noise-induced hearing loss (NIHL) during a 40-year lifetime exposure at the 85-dBA REL. NIOSH has also found that scientific evidence supports the use of a 3-dB exchange rate for the calculation of TWA exposures to noise. The recommendations in this document go beyond attempts to conserve hearing by focusing on prevention of occupational NIHL. For workers whose noise exposures equal or exceed 85 dBA, NIOSH recommends a hearing loss prevention program (HLPP) that includes exposure assessment, engineering and administrative controls, proper use of hearing protectors, audiometric evaluation, education and motivation, recordkeeping, and program audits and evaluations. Audiometric evaluation is an important component of an HLPP. To provide early identification of workers with increasing hearing loss, NIOSH has revised the criterion for significant threshold shift to an increase of 15 dB in the hearing threshold level (HTL) at 500, 1000, 2000, 3000, 4000, or 6000 Hz in either ear, as determined by two consecutive tests. To permit timely intervention and prevent further hearing losses in workers whose HTLs have increased because of occupational noise exposure, NIOSH no longer recommends age correction on individual audiograms.

Noise is an increasing problem in everyday life, and many noise-induced hearing problems are irreversible. This book focuses on all aspects of noise-related problems, including noise effects on stress levels, functional changes after noise-induced cochlear damage, occupational hearing loss and noise conservation problems.

The WHO Regional Office for Europe set up a working group of experts to provide scientific advice to the Member States for the development of future legislation and policy action in the area of assessment and control of night noise exposure. The working group reviewed available scientific evidence on the health effects of night noise, and derived health-based guideline values. In December 2006, the working group and stakeholders from industry, government and nongovernmental organizations reviewed and reached general agreement on the guideline values and key texts for the final document of the "Night noise guidelines for Europe". Considering the scientific evidence on the thresholds of night noise exposure indicated by "Lnight,outside" [L suffix night,outside] as defined in the Environmental Noise Directive (2002/49/EC), an Lnight, outside of 40 dB should be the target of the night noise guideline (NNG) to protect the public, including the most vulnerable groups such as children, the chronically ill and the elderly. "Lnight,outside" value of 55 dB is recommended as an interim target for the countries where the NNG cannot be achieved in the short term for various reasons, and where policy-makers choose to adopt a stepwise approach. These guidelines are applicable to the Member States of the European Region, and may be considered as an extension to, as well as an update of, the previous WHO "Guidelines for community noise" (1999).

Improved housing conditions can save lives, prevent disease, increase quality of life, reduce poverty, and help mitigate climate change. Housing is becoming increasingly important to health in light of urban growth, ageing populations and climate change. The WHO Housing and health guidelines bring together the most recent evidence to provide practical recommendations to reduce the health burden due to unsafe and substandard housing. Based on newly commissioned systematic reviews, the guidelines provide recommendations relevant to inadequate living space (crowding), low and high indoor temperatures, injury hazards in the home, and accessibility of housing for people with functional impairments. In addition, the guidelines identify and summarize existing WHO guidelines and recommendations related to housing, with respect to water quality, air quality, neighbourhood noise, asbestos, lead, tobacco smoke and radon. The guidelines take a comprehensive, intersectoral perspective on the issue of housing and health and highlight co-benefits of interventions addressing several risk factors at the same time. The WHO Housing and health guidelines aim at informing housing policies and regulations at the national, regional and local level and are further relevant in the daily activities of implementing actors who are directly involved in the construction, maintenance and demolition of housing in ways that influence human health and safety. The guidelines therefore emphasize the importance of collaboration between the health and other sectors and joint efforts across all government levels to promote healthy housing. The guidelines' implementation at country-level will in particular contribute to the achievement of the Sustainable Development Goals on health (SDG 3) and sustainable cities (SDG 11). WHO will support Member States in adapting the guidelines to national contexts and priorities to ensure safe and healthy housing for all.

This two-volume work discusses environmental health, the branch of public health concerned with all aspects of the natural and built environment affecting human health, and addresses key issues at the global and local scales. The work offers an overview of the methodologies and paradigms that define this burgeoning field, ranging from ecology to epidemiology, and from pollution to environmental psychology, and addresses a wide variety of global concerns including air quality, water and sanitation, food security, chemical/physical hazards, occupational health, disease control, and injuries. The authors intend to provide up-to-date information for environmental health professionals, and to provide a reference for students and consultants working at the interface between health and environmental sectors. Volume 2 covers the technological, legislative, and logistical solutions for coping with environmental health issues. The principles of environmental legislation are explained in national and international contexts, and assessments are mapped out to craft informed governance plans for health and environmental management. Mitigation measures are introduced to control wastewater and solid waste management and air and noise pollution, and adaptation strategies for emergency preparedness and disaster recovery are discussed.
