Noise, or the unwanted sound, is among the universal occupational health problems. It is a by-product of several industrial processes. Sound comprises of pressure changes of the medium that is caused by turbulence or vibration. These pressure changes usually produce waves originating away from the vibrating or turbulent source.
The degree of damage relies initially on the noise’s intensity and the period of the exposure. Hearing loss which happens to be noise-induced can be permanent or temporary. The temporary hearing loss comes from short-term noise exposures, with the normal hearing returning just after resting for a while. Generally, lengthy exposure to the high levels of noise over a specific period leads to permanent harm.
