Industrial deafness is one of the most common forms of hearing loss. A recent US study revealed that up to 3 out of 4 factory and construction workers suffer noise induced hearing loss (Industrial deafness). The degree of hearing loss will depend on the level of some degree of noise and the duration of exposure to the noise. Loud noise does not produce pain in your ears and therefore people assume there is no damage if there is no pain this is simply not true. Permanent and irreversible.
If you are or were surrounded by noise at some stage in your life it is important to have your hearing regularly monitored.
