Health Effects of Loud Noise
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. Short term exposure to loud noise can also cause a temporary change in hearing (your ears may feel stuffed up) or a ringing in your ears (tinnitus). These short-term problems may go away within a few minutes or hours after leaving the noise. However, repeated exposures to loud noise can lead to permanent tinnitus and/or hearing loss.
Loud noise can create physical and psychological stress, reduce productivity, interfere with communication and concentration, and contribute to workplace accidents and injuries by making it difficult to hear warning signals. The effects of noise induced hearing loss can be profound, limiting your ability to hear high frequency sounds, understand speech, and seriously impairing your ability to communicate.
Hearing Conservation Program
Hearing conservation programs strive to prevent initial occupational hearing loss, preserve and protect remaining hearing, and equip workers with the knowledge and hearing protection devices necessary to safeguard themselves. Employers are required to measure noise levels; provide free annual hearing exams, hearing protection, and training; and conduct evaluations of the adequacy of the hearing protectors in use (unless changes made to tools, equipment, and schedules result in worker noise exposure levels that are less than the 85 dBA). Research indicates that workplaces with appropriate and effective hearing conservation programs have higher levels of worker productivity and a lower incidence of absenteeism.
Sound Measurement Applications
Construction & boundary noise – American National Standards Institute (ANSI)
A10.46, Hearing Loss Prevention for Construction and Demolition Workers. Helps employers prevent occupational hearing loss among construction and demolition workers and applies to all construction and demolition workers with potential noise exposures (continuous, intermittent and impulse) of 85 decibels, A-weighted (dBA) and above. It was approved by ANSI on March 5, 2007, and by the American Society of Safety Engineers (ASSE) on March 20, 2007.
