Throughout the world, the health hazards of noise and vibration exposure in the workplace have been recognized, and are subject to safety standards. Most jurisdictions have Occupational Health and Safety legislation in place, which not only specifies maximum safe exposure levels, but also stipulates the employer’s responsibilities.
Identifying the Key Sources of Sound & Vibration
Nowadays, it is generally not sufficient to identify areas of high sound levels in the workplace, and provide ear plugs or muffs for workers in those areas. Instead, it is often the employer’s responsibility first to investigate whether engineered noise control measures are feasible, to keep the noise levels acceptably low to alleviate the need for hearing protectors. This responsibility means that the noise and vibration consultant must know more than just how to measure the sound levels throughout the facility. The consultant must also be expert in the more detailed task of identifying the key sources of sound and vibration, determining which sources must be reduced, and recommending specific noise control measures.
Workplace Noise & Vibration Control Expertise
Over the past two decades, HGC Engineering has undertaken hundreds of workplace noise and vibration studies – from 1000 MW power plants to oil refineries to large scale food production plants – not only to measure and evaluate the worker exposure levels, but also to develop effective control strategies when excessive noise or vibration are found.
If you are the health and safety representative at an industry, an industrial hygienist or an owner/manager of an industry, you may need to complete a workplace noise or vibration study, either to satisfy a regulator, or for internal best practices.
Review Noise & Vibration Limits
We will review with you the applicable noise and vibration limits. For noise, the exposure limit is often 85 dBA or 90 dBA, depending on the jurisdiction. The limits for exposure to vibration are more complex, and depend on whether the situation involves whole body vibration, or hand-arm vibration when using tools or equipment in some cases, corporations have internal limits that are more stringent than those stipulated by the local regulators.
Community & Urban Noise:
Most Indians think of cities as noisy places – but some parts of Indian cities are much louder than others. Nationwide, neighborhoods with higher poverty rates and proportions of Hispanic and Asian residents have higher noise levels than other neighborhoods. In addition, in more racially segregated cities, living conditions are louder for everyone, regardless of their race or ethnicity.
As environmental health researchers, we are interested in learning how everyday environmental exposures affect different population groups. In a new study we detail our findings on noise pollution, which has direct impacts on public health.
Today, Scientists have documented that environmental hazards, such as air pollution and hazardous waste sites, are not evenly distributed across different populations. Often socially disadvantaged groups such as racial minorities, the poor and those with lower levels of educational attainment experience the highest levels of exposure. Our research shows that like air pollution, noise exposure may follow a similar social gradient. This unequal burden may, in part, contribute to observed health disparities across diverse groups in India and elsewhere.
A growing body of evidence links noise from a variety of sources, including air, rail and road traffic, and industrial activity to adverse health outcomes. Studies have found that kids attending school in louder areas have more behavioral problems and perform worse on exams. Adults exposed to higher noise levels report higher levels of annoyance and sleep disturbances.
