Noise-induced hearing loss is sensory deafness caused by long-term exposure of the auditory system to a noisy environment. Auditory fatigue is an early symptom of noise-induced hearing loss, and hearing can gradually recover after people leave a noisy environment.
You can make “hearing health” a part of your lifestyle. Stay away from loud or prolonged noises when you can. Turn down the music volume. Buy power tools that have sound controls. When you must be around noise, either at work or at play, use something to protect your hearing.
Loud Noise Can Cause Hearing Loss Quickly or Over Time
Hearing loss can result from a single loud sound (like firecrackers) near your ear. Or, more often, hearing loss can result over time from damage caused by repeated exposures to loud sounds. The louder the sound, the shorter the amount of time it takes for hearing loss to occur. The longer the exposure, the greater the risk for hearing loss ...
ICD-10 code H91. 93 for Unspecified hearing loss, bilateral is a medical classification as listed by WHO under the range - Diseases of the ear and mastoid process .
According to the Ministry of Health (2006), Noise-Induced Hearing Loss (NIHL) is hearing loss caused by prolonged exposure to noise. It is characterized as sensorineural hearing loss and is usually bilateral, irreversible, and progressive while the exposure to noise continues.
Hearing loss can result from damage to structures and/or nerve fibers in the inner ear that respond to sound. This type of hearing loss, termed “noise-induced hearing loss,” is usually caused by exposure to excessively loud sounds and cannot be medically or surgically corrected.

A noise-induced hearing loss usually affects both ears. In some rare cases, it can also occur in one ear only – this is called a unilateral hearing loss. This can occur if you experience a sudden very loud sound close one of your ears.
Symptoms of noise-induced hearing lossYou have pain in your ears following loud noise exposure.Other people comment that you're talking loudly or shouting.You have tinnitus—ringing, whooshing, roaring or buzzing sounds in your ears.You may experience diplacusis, or "double hearing," though this is rare.
NIHL can be immediate or it can take a long time to be noticeable. It can be temporary or permanent, and it can affect one ear or both ears.
Hearing loss affects people of all ages and can be caused by many different factors. The three basic categories of hearing loss are sensorineural hearing loss, conductive hearing loss and mixed hearing loss.
Having sensorineural hearing loss means there is damage either to the tiny hair cells in your inner ear (known as stereocilia), or to the nerve pathways that lead from your inner ear to the brain. It normally affects both ears. Once you develop sensorineural hearing loss, you have it for the rest of your life.
A bilateral hearing loss is a hearing loss in both ears. A bilateral hearing loss can have different degrees: mild, moderate, severe or profound. The bilateral hearing impairment may be caused by factors in the outer, middle or inner ear or a combination of these areas.
5: Sensorineural hearing loss, unspecified.
While a single loud concert probably won't cause any permanent damage to your hearing system, repeated exposure can. Repeated episodes of TTS can become permanent threshold shift (PTS).
Otosclerosis is a form of conductive hearing loss. In some cases, as the ear loses its ability to transmit sound, people may first notice low-frequency hearing loss, meaning that low-pitched sounds are harder to hear.
NIHL can result from a one-time exposure to a very loud noise, like a nearby explosion or a shotgun firing. You're more likely to lose your hearing gradually, however, from sounds that aren't as loud but that you're exposed to repeatedly for long periods.

Conductive hearing loss occurs when sound is not conducted efficiently through the outer ear canal to the eardrum and ossicles of the middle ear. Conductive hearing loss usually involves a reduction in sound level or the ability to hear faint sounds. This type of hearing loss can often be corrected medically or surgically.
Hearing loss is a common problem caused by noise, aging, disease, and heredity. According to the National Institutes of Health, an estimated one-third of people in the U.S. between the ages of 65 and 75 have some degree of hearing loss, while close to one-half of people over 75 years of age are affected.
There is also a subcategory (H91.2) for sudden idiopathic hearing loss, which is for sudden hearing loss with no known no cause. H90.0 Conductive hearing loss, bilateral.
Most of the time, SNHL cannot be medically or surgically corrected. This is the most common type of permanent hearing loss. Mixed hearing loss is conductive hearing loss with sensorineural hearing loss. In other words, there may be damage in the outer or middle ear, and in the inner ear (cochlea) or auditory nerve.
Any medication that damages the ear and causes hearing loss is considered ototoxic. The damage may be permanent, or may return to normal after the medication is stopped. It may occur in one or both ears, and may not be to the same degree in both ears. Presbycusis is hearing loss that occurs gradually as a person ages.
This type of hearing loss can often be corrected medically or surgically. Sensorineural hearing loss (SNHL) occurs when there is damage to the inner ear (cochlea), or to the nerve pathways from the inner ear to the brain. SNHL reduces the ability to hear faint sounds.
There is no history of ear discharge, tinnitus, vertigo, or trauma. Otoscopic exam reveals both ear canals and TMs to be normal. Tuning for tests confirmed left conductive hearing loss. Proper coding is H90.12 Conductive hearing loss, unilateral, left ear, with unrestricted hearing on the contralateral side.
