Noise (Hearing Conservation)
Exposure to loud or prolonged noise can cause permanent hearing loss. TWU conducts regular monitoring to determine if members of the University community are exposed to harmful noise levels.
Based on current research and recommendations of various health and safety organizations, the Office of Environmental Health & Safety has determined that instead of using the OSHA “criterion level” of 90 dB, TWU will use 85 dB (which is half the dose of 90 dB). In other words; TWU employees exposed to noise levels of 85 dB or greater averaged over an 8-hour time period must be included in the Hearing Conservation Program, and engineering controls and personal protective equipment must be utilized to keep their actual exposure below 85 dB.
Employees in the Hearing Conservation Program must participate in annual training covering an overview of noise and its measurement, health hazards of noise, permissible noise levels, monitoring, audiometric testing, hearing protection, recordkeeping, and sources of noise. Employees included in the program must also have their hearing tested annually.
