3M leads the advancement of hearing conservation at 2012 OSH Expo Africa


June 2012

Hearing loss caused by exposure to noise at work continues to be a significant occupational hazard . With this in mind, 3M’s Hearing Protection solutions can play a vital part in avoiding employee health issues and limit the possibility of costly future litigation against the employer.

At this year’s OSH Expo Africa 3M showcased its Hearing Protection product range, along with other occupational health solutions, namely Masks and Respirators, Disposable Coveralls, Welding Helmets, Safety Eyewear and Reflective Material

The OSH Expo Africa is an informative and exciting showcase of Occupational Safety and Health (OSH) products and services that will provide OSH professionals with all the latest industry news, trends and the opportunity to view and source the most innovative products. This year, 3M showcased its Occupational Health division by hosting live demonstrations of their 3M™E-A-RFit™ Validation System and Respiratory Fit Testing.

With a key focus on hearing conservation programmes, the 3M™ E-A-RFit™ Validation System, is an objective, quantitative hearing protector fit-test system that takes Hearing Conservation to the next level. Environmental controls, hearing protectors, and on-the-job training are the first steps to protecting your workers against noise-induced hearing loss (NIHL).

The 3M™E-A-RFit system assists in achieving optimal fit through hearing protector selection and employee training. In less than eight seconds per ear, the system generates a personal attenuation rating (PAR) that indicates a worker’s noise reduction levels for a given fitting and hearing protector. Researchers at E-A-RCal Laboratory developed proprietary algorithms to analyze sound pressure inside ear canals. This in-the-ear testing procedure differs from many other systems on the market by providing quantitative data that does not rely on subject response, and you can compare ratings across hearing protectors and fittings to determine the best fit.

Other products within the 3M hearing protection category include a complete range of ear plugs and passive ear muffs designed to provide protection, comfort and ease of use.

All 3M Hearing Protection products are designed to be both practical and comfortable. Comfort is a priority, combining the correct level of noise protection with ease of use.
