Noise is one of the occupational health disorders affecting workers in various professions. Traffic noise is a one of the source of environmental pollution in developed and developing nations. Recent reports suggest that, outside Europe and North America, up to 25% of adult males of working age have evidence of occupational noise induced hearing loss. This seems to be a particular problem in those countries moving from agriculture to a stronger manufacturing base for their developing economies. Noise induced hearing loss refers to exposure of loud sounds beyond 85db over a period of time. Sounds of 130 dB (A) or greater will cause hearing damage after even short time periods in almost all exposed individuals. noise induced hearing loss is preventable through early intervention. There is evidence that the use of hearing protection reduces the risk of noise induced hearing loss from noise in both recreational and occupational contexts. As regards hearing protection, the choice is between earplugs, earmuffs earplugs can be assumed to give approximately 10–15 dB of sound attenuation and earmuffs at least 15 dB and active noise reduction early detection of noise induced hearing loss can be made by use of pure tone audiometry.
