Noise-induced Hearing Loss (or NIHL) is permanent damage to the sensitive hearing organ, the cochlea, and or auditory nerve, caused by exposure to loud sounds in the environment. This description is based on the pure tone average (PTA), which is the average loss at 0.5, 1 and 2 kHz measured with the pure tone audiogram. One of the most common causes of hearing loss is from excessive noise exposure, known as noise-induced hearing loss (NIHL). Noise induced hearing loss is one of most common hearing deficit which is almost completely preventable.

Noise induced hearing loss is caused by exposure to excessively loud noise for longer periods e.g. Noise-induced hearing loss (NIHL) is hearing impairment resulting from exposure to loud sound.People may have a loss of perception of a narrow range of frequencies or impaired perception of sound including sensitivity to sound or ringing in the ears. 2012 Mar 3. . The louder the noise and the more often a person is exposed to it, the more it harms their hearing. NIHL can be immediate or it can take a long time to be noticeable.

To use the daily exposure ready-reckoner you will need to know the levels of noise and durations of exposure which make up a person's working day.

Dental personnel exposed to occupational noise may experience hearing loss. Speech may be heard but not completely understood. Entitlement . Eur Arch Otorhinolaryngol. It occurs when we are exposed to harmful noise concentrations, whether on a long or short-term basis.

Noise-induced hearing loss occurs when the sensitive structures in the inner ear are damaged by loud sound. Whether a noise is harmful depends on how loud it is and how long you're around it. Noise-induced hearing loss is the only type of hearing loss, which is absolutely preventable. Noise-induced hearing loss (NIHL), along with age-related hearing loss, is one of the most common forms of hearing loss.
