<P> Hearing conservation programs are designed to prevent hearing loss due to noise . Regarding occupational exposures to noise , a written hearing conservation program is required by the Occupational Safety and Health Administration ( OSHA ) `` whenever employee noise exposures equal or exceed an 8 - hour time - weighted average sound level ( TWA ) of 85 decibels ( dB ) measured on the A scale ( slow response ) or , equivalently , a dose of fifty percent . '' This 8 - hour time - weighted average is known as an exposure action value . While the Mine Safety and Health Administration ( MSHA ) also requires a hearing conservation program , MSHA does not require a written hearing conservation program . MSHA 's hearing conservation program requirement can be found in 30 CFR § 62.150 , and requires has almost the same exact requirements as the OSHA hearing conservation program requirements . Therefore , only the OSHA standard 29 CFR 1910.95 will be discussed in detail . </P>
