OSHA 3498-12N, Worker Safety Series: Protecting Yourself from Noise in Construction, addresses the issue that exposure to high levels of noise can cause permanent hearing loss. Neither surgery nor a hearing aid can help correct this type of hearing loss. Construction sites have many noisy operations and can be a significant source of noise exposure. Loud noise can also reduce work productivity and contribute to workplace accidents by making it difficult to hear warning signals. Hearing loss from loud noise limits your ability to hear high frequencies, understand speech, and reduces your ability to communicate, which can lead to social isolation. Hearing loss can affect your quality of life by interfering with your ability to enjoy socializing with friends, playing with your children or grandchildren, or participating in other activities. Damage to your hearing can be prevented, but once permanent noise-induced hearing loss occurs, it cannot be cured or reversed. Hearing loss usually occurs gradually, so you may not realize it is happening until it is too late. Noise can also affect your body in other ways. A recent study found that workers persistently exposed to excessive occupational noise may be two-to-three times more likely to suffer from serious heart disease than workers who were not exposed.
