Noise, or unwanted sound, is a pervasive problem that affects people both on the job and away from the workplace. Noise-induced hearing loss can be prevented through a successful workplace hearing conservation program. The greatest benefit for the affected employees is possible prevention of hearing impairments. The employer benefits from reduced medical expenses and workers' compensation costs as they relate to occupational noise-induced hearing loss. Unlike other health conditions, noise-induced hearing loss cannot be treated or repaired.
Hearing is damaged permanently and can even become worse.
Eventually, a hearing aid may be needed. Hence, the need to emphasize prevention. Participating employees should be informed of the effects of noise on hearing. They should also learn the purpose of hearing protectors, their advantages and disadvantages, attenuation of various types, and instructions on the selection, fitting, use and care of these devices. The training should also cover the purpose of audiometric testing and an explanation of the test procedures.
