Noise-induced hearing loss is hearing impairment resulting from exposure to loud sound people may have a loss of perception of a narrow range of frequencies, impaired cognitive perception of sound or other impairment, including sensitivity to sound or ringing in the ears.
The hearing may deteriorate gradually from chronic and repeated noise exposure such as loud music or background noise or suddenly from a short high-intensity noise, such as a gunshot or air heard in both types loud, sound / stimulates delicate hearing cells leading to the permanent injury or death of The cells.
Once lost hearing cannot be restored in humans when exposed to hazards such as noise, which occur at work and is associated with hearing loss.
It is referred to as Occupational hearing loss. There are a variety of prevention strategies available to avoid or reduce hearing loss. If not prevented hearing loss can be managed through assistive devices and cognitive therapies.
Prevention is the best defense against noise induced hearing loss. The best first option for protecting hearing is lowering the volume of sounds at its source. Secondly, limiting the time of exposure to loud noise can reduce injury.
Finally, physical protection from the noise can reduce its impact. Government regulations are designed to limit occupational exposure to dangerously loud noise. The largest burden of Nile has been through occupational exposures.
However, noise induced hearing loss can also be due to unsafe recreational residential, social and military service related noise exposures. It is estimated that 15 percent of young people are exposed to sufficient leisure noises.
That is concert’sporting events, daily activities, personal listening devices etc to cause Nile. There is not a limited list of noise sources that can cause hearing loss. Rather, it is important to understand that exposure to excessively high decibel levels from any sound source over time can cause hearing loss.
