The audiogram shows hearing loss patterns (individual plots with labels along the right side) for white males at ages 20, 30, 40, 50 and 60 years with 0, 10, 20, 30, and 40 years of cumulative noise exposure, respectively.
Repeated and prolonged exposure to sounds over 85 dBA will damage the sensitive hair cells of the inner ear and possibly the hearing nerve.

Noise-induced hearing loss most often results in permanent damage which cannot be treated medically. Wear hearing protection (foam or silicone plugs or muffs) when around loud equipment such as a lawn mower, power saw or leaf blower. Check with your employer regarding federal noise regulations if you are exposed to loud noise at work. Avoid medications that can be dangerous to your hearing a€“ ask a physician about possible ototoxic effects. Studies show that young people ages 11 to 19 are increasingly experiencing some sort of hearing impediment. According to Randy Judson, AuD, clinical director of audiology services at the New York Ear and Eye Infirmary, hearing loss falls into three categories: The first is conductive (CHL), which is usually due to issues in the middle ear, like a ruptured eardrum, water, ear infection or abnormal hearing bones.

One in 10 Americans has a hearing loss that affects his or her ability to understand normal speech. Over time, sounds may seem distorted or muffled, and it may become increasingly difficult to understand speech. As NIHL progresses, the hearing loss may eventually spread to frequencies where human speech is pervasive…in the range of 500-3000 Hz. For example, right-handed shooters tend to develop greater NIHL in the left ear, which is closer to the gun muzzle than the right ear. These delicate structures can be damaged permanently by intense noise, such as an explosion or gunshot, or by continuous exposure to harmful noise over a period of time. Untreated hearing loss leads to serious negative lifestyle changes, which often effect family, friends, and others.

About one third of the 28 million Americans with hearing loss likely developed NIHL from noise at work or leisure activities. Acoustic trauma can cause NIHL in only one ear, when a loud blast from an explosion affects the ear nearest the explosion.


Affliction rates in boomers are fast approaching the half-way mark, with roughly 44 percent showing signs of significant hearing loss by age 69. This comes from nerve problems which can stem from exposure to loud noises, certain medications, genetics and aging.

Noise is one of the most common occupational health hazards, and NIHL is the main concern in industrial, manufacturing, entertainment, and farming environments.
Continued excessive exposure often results in decreased sensitivity to other types of sound, eventually impacting speech understanding. The scientists, who have been tracking adolescent hearing since 1988, have noticed a whopping 31 percent rise in hearing loss.
That’s nearly one out of every two people requiring a Miracle Ear or some other hearing aid.
And Regal Cinemas just stepped up its deployment of Sony Entertainment’s Access System, to support the moviegoing experience for deaf or blind patrons. You’ll want to nip the problem — and the behavior that might be causing it — in the bud, if you can.
