NIOSH reports that noise-induced hearing loss and related effects are the most common work-related diseases. In the US, 22 million workers are exposed to hazardous noise intensities. An effective written hearing protection program includes policies and procedures for noise monitoring, employee training, selection and use of hearing protection devices, equipment and facility noise reduction engineering, and audiometric testing. There are significant differences between occupational exposure limits established by OSHA and the National Institute for Occupational Safety and Health (NIOSH). Course topics include: basic physics of sound and vibration, anatomy and physiology of the ear and the hearing process, effects of noise on hearing, noise monitoring, noise regulations and standards, noise control engineering, selection of hearing protective devices and the role of audiometric testing. Participants will draft hearing protection policies and procedures for mock office, manufacturing and construction site use and adaptation.
