At present exposure limits, one in four will develop a permanent hearing loss as a result of their occupational exposure to these hazards. The gradual progression of hearing loss due to noise may be less dramatic than an injury resulting from a workplace accident, but it is a significant and permanent handicap for the affected individual.
Loss of hearing denies people sensory experiences that contribute to the quality of their lives.
For some, loss of hearing may impede their ability to be gainfully employed. This tragedy is preventable. There are other NORA Priority Research Areas that may be linked with Hearing Loss. Noise is the most important occupational cause of hearing loss, but solvents, metals, asphyxiants, and heat may also play a role. Exposure to noise, combined with other agents can result in hearing loss greater than those resulting from exposure to noise or other agents alone.
