A Multidisciplinary Study of Factors Influencing Hazard Reduction Strategies, Using Noise Exposure and Hearing Loss as a Model

Noise exposure is a serious problem in many B.C. workplaces. Although workplaces have hearing conservation programs in place as required by law, these programs often fail to include engineered noise controls (ENCs) to the extent they could. ENCs reduce the noise exposure of workers by stopping noise at the source, and are an effective way to prevent occupational-related hearing loss. This study explored barriers to the use of ENCs, through interviews with staff and audits of hearing conservation programs at eight BC workplaces in the food and beverage manufacturing sector.

Workplace Hearing Loss

Work-related hearing loss continues to be a critical workplace safety and health issue. It is estimated that over 22 million workers are exposed to hazardous noise on the job and an additional nine million are at risk for hearing loss from other agents such as solvents and metals. The National Institute for Occupational Safety and Health (NIOSH) has a long history of working to prevent workplace hearing loss. While noise-induced hearing loss is 100 percent preventable, once acquired, hearing loss is permanent and irreversible.

NIOSH is interested in strengthening its efforts to prevent hearing loss in the workplace. Through this blog, NIOSH would like to learn more about: practices that have proven useful, government policies that can be improved, Tools that have been effective, etc.

Estimating Dose-Response Relationships between Noise Exposure and Human Health in the UK

Across Europe attention is increasingly turning to the detrimental impacts of noise pollution. The rapidly growing literature surrounding noise pollution highlight a wide range of detrimental impacts including annoyance, adverse health impacts, slower learning rates in children, irritation and effects on local ecology.

Experts in this area undertake a review of research into the links between noise and health. The four key aims of this research were:

  • Identify a comprehensive list of potential adverse health impacts from noise and review the current state of evidence for each of the impacts;
  • Where a robust evidence base exists, to recommend quantitative links (dose-response functions ) for the impacts of noise on health which could be applied in the UK;
  • Identify any emerging adverse health impacts that should be kept under review for future consideration in evaluation; and
  • Identify any structural challenges to developing and maintaining strong quantitative links between noise and health outcomes.

This research has now been completed.

RR727 - Market surveillance of custom-moulded earplugs

A study of a selection of CE-marked custom-moulded earplugs available in the UK was carried out in order to examine the protection provided by such devices, and to identify any influencing factors on protection, comfort and fit.

Proceedings of the Second American Conference on Human Vibration

There is a saying, "If it moves, it vibrates." This is especially true in our modern industrial environments, where workers use powered tools, machinery, vehicles, and heavy equipment. How workers are affected by these elements of the industrial working environment is a concern of health professionals, governments, and scientists around the world. How to adequately assess the effects of human vibration exposure is an equally important issue.

EEA draws the first map of Europe's noise exposure

The European Environment Agency (EEA) has launched the most comprehensive map of noise exposure to date, revealing the extent to which European citizens are exposed to excessive acoustic pollution.

Evaluation of Health Concerns at a Printed Circuit Board Manufacturing Plant

The Health Hazard Evaluation (HHE) Programme evaluated employees' concerns about exposure to lead solder paste and fumes and noise at a printed circuit board manufacturing plant. Investigators found that auto insertion operators' noise exposures were very low. Investigators found lead on employees' hands, on work surfaces, and in a break room. Investigators recommended improving general housekeeping and using engineering controls when removing solder dross and cleaning wave solder machines.
