CAOHC Releases Education Video on Workplace Noise Concerns and Controls

When is the workplace too loud? A new video from the Council for Accreditation in Occupational Hearing Conservation (CAOHC) answers this question for those concerned about hearing conservation and offers noise control options. The video, titled “Workplace Noise: Measurement and Controls,” takes the viewer through facts, measures, and strategies surrounding occupational noise.

“While the video was initially created for Course Directors to teach Noise Measurement and Control and the Physics of Sound, it is also ideal for employers who need a starting point in developing a hearing conservation program, for Industrial Hygiene professionals to educate their workforce, for managers, new safety professionals, and educators instructing occupational health,” said CAOHC executive director Kim Stanton.

“The accessible and engaging nature of the video makes it ideal to use in training,” said Stanton. “It offers a consistent, predictable message whenever you need it, making it cost effective for many audiences.” The video also includes digital resources such as a companion manual, reference charts, a glossary of terms, and test questions and answers.

Content for the video was contributed by 17 different experts in the hearing conservation field. “A great deal of editing and rework went on to assure all the facts and images were accurate and approved by the entire CAOHC Council,” said Brent Charlton, council member, who served as project manager for the video. The video has six modules of learning that can be viewed as one 40-minute video or individually in 5- to 7-minute segments. The modules are: (1) Characteristics of Sound, (2) Enter the Decibel, (3) Time-Weighted Average, (4) Permissible Exposure Limit, (5) Noise Control Strategies, and (6) Measuring Noise.
