Damage from noise exposure of sufficient intensity and duration is well established and hearing loss may be temporary or permanent. Fortunately, noise exposure can be controlled and technology exists to reduce the hazards. Aside from employer/employee concern with the inherent hazards of noise, added attention has been brought to focus on the subject through regulatory requirements. Under the Occupational Safety and Health Act (OSHA) every employer is legally responsible for providing a workplace free of hazards such as excessive noise. It has been estimated that 14 million US workers are exposed to hazardous noise. This book is presented as an overview summary for employers, workers, and supervisors interested in workplace noise and its control. We believe that in order to understand and control noise it is not necessary to be highly technical. Noise problems can quite often be solved by the people who are directly affected. Presented is an overview of noise, the regulations concerning its control, an explanation of specific principles, and a discussion of some particular techniques.

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.

Manufacturing industry is one of the most important sectors that contribute significantly to the economy of Malaysia. More than half a million workers in Malaysia work in this industry and many of them are exposed to loud noises of more than 85dB that is harmful to health. Noise induced hearing loss (NIHL) is the highest reported occupational disease affecting around 16% of workers globally. In this book, we reported a study conducted in 26 manufacturing industries that employed around 270,000 workers with more than 40% of them were exposed to noises that potentially cause NIHL. This cross-sectional study designed with face-to-face interviews using questionnaires conducted among Occupational Safety and Health practitioners and workers selected from these industries. Direct and indirect cost was imputed component covering cost of medical care and rehabilitation, transportation, loss of productive time and investigations. Costing data in the government hospital was obtained from casemix information system from a tertiary teaching hospital. The study confirmed that NIHL among workers in manufacturing industry imposed a huge economic burden for Malaysia. In order to mitigate this problem, the existing and yet out-dated noise regulation need to be reviewed. Meanwhile employers need to implement hearing conservation program more effectively.

Every day, millions of employees in Europe are exposed to loud noise at work. This is the case not just in heavy industries but also in a wide range of sectors including agriculture and service industries. Noise at work has been designated at the theme for the European Week for Safety and Health 2005, and this report examines noise control measures including relevant European Directives and supporting international standards. It looks at interventions in the workplace to examine and prevent the risks arising from noise exposure in terms of personal, social and economic cost of ill health and accidents.
