Hearing is the ability to detect sounds through an organ. We hear sounds from an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. The sound may we hear through solid, liquid or gaseous matter. The commonly stated range of human hearing is 20 to 20000 Hz. Humans can hear sounds as low as 12Hz and as high as 28Khz.

Conviction Of Hearing Loss
Hearing loss is caused by many factors, most frequently from natural ageing or listening to very loud noise.
Most Common Causes Of Hearing Loss
Ageing is the most common cause of hearing loss. As the person becomes obsolete most probably there are chances of hearing loss. This may occur because of changes in the inner ear and auditory nerve. Due to this, it is hard to tolerate loud sounds or to hear what another person is saying.
As of today’s generation, listening to loud music can further create problems of hearing loss. Noise exposure can cause permanent hearing loss. Harsh noise can create physical and psychological stress. Sometimes exposure to high levels of noise can contribute to workplace accidents and injuries as it is difficult to hear the warning signals at an elevated level of noise.
Head trauma can also cause hearing loss. If an accident causes head injury then it can cause damage to any part of the outer or the inner ear. So this is also a cause of hearing loss.
Virus Or Diseases
The virus can cause acquired hearing loss. This hearing loss occurs after birth. Diseases that can cause hearing loss include measles, chickenpox and mumps.
