Exposure to loud or prolonged noise can cause permanant hearing loss. TWU will conduct monitoring to determine if members of the University community are exposed to harmful noise levels. 

Employees who are exposed to an average noise level of of 85 decibels (dB) or higher, over an 8-hour time period, must be included in the TWU Hearing Conservation Program.  Employees exposed over 90 dB will be required to wear hearing protection, such as ear plugs or ear muffs.

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.
