Your ability to hear sounds is evaluated by audiometry. Based on their volume (intensity) and the rate at which sound waves vibrate, sounds differ (tone). Sound waves cause the inner ear's nerves to fire, which results in hearing. The sound then makes its way to the brain via nerve connections. The ear canal, eardrum, and middle ear bones are all possible passageways for sound waves to reach the inner ear (air conduction). They can also penetrate the bones behind and surrounding the ear (bone conduction). After a few hours, hearing damage might result from noise levels above 85 dB. Louder noises might be painful right away, and hearing loss can appear extremely quickly. Your health care provider may test your hearing with simple tests that can be done in the office. These may include completing a questionnaire and listening to whispered voices, tuning forks, or tones from an ear examination scope.
