Tinnitus And Hearing Loss From Harmful Noise (NIHL)

[imwb_socialbuzz] By John On December 6, 2012 Under Tinnitus

The sad part about tinnitus from harmful noise is that it is 100% preventable! And yet it is the No.1 disability our returning servicemen and women are left with! This is crazy! Surely one of the very first things a new recruit should be exposed to is a few veterans who have tinnitus from exposure to extreme noises!

  • Veterans will surely be able to pass on the message to the new recruits in a dramatic and real way!
  • Getting back in one piece is obviously important to all our people in the service, so why is it that so many return from active duty with their hearing irreparably damaged?
  • Why do they have to suffer with distorted hearing and tinnitus for the rest of their lives?

“Tinnitus Is The No. 1 disability affecting veterans, active-duty service members

A recent report from the U.S. Department of Veterans Affairs revealed more than 10 percent of all veteran disability claims in fiscal year of 2011 were due to tinnitus, an early sign of hearing loss.

“A lot of the military occupational specialties that Marines will occupy involves either shooting a weapon or being near demolitions, generator noise and engine noise,” McArthur said, adding that 18 percent of active duty Camp Lejeune Marines are currently suffering from some degree of tinnitus.

Infantry Marines are the most at risk for developing tinnitus, as 29 percent of the Marines in that MOS suffer from the disorder, McArthur said.

Similarly, 21 percent of artillery Marines suffer from tinnitus, as do 19 percent of Marines working in explosive ordnance disposal.”

I still find it amazing that so many serviceman and women who are giving their all for the country, are left with tinnitus after a tour of duty. Often they begin to experience the noise induced hearing loss (NIHL) during the initial training period, such are the levels of noise they can be exposed to!


“What is noise-induced hearing loss?

Illustration showing the sound pathway.

Every day, we experience sound in our environment, such as the sounds from television and radio, household appliances, and traffic. Normally, we hear these sounds at safe levels that do not affect our hearing.

However, when we are exposed to harmful noise—sounds that are too loud or loud sounds that last a long time—sensitive structures in our inner ear can be damaged, causing noise-induced hearing loss (NIHL).

These sensitive structures, called hair cells, are small sensory cells that convert sound energy into electrical signals that travel to the brain. Once damaged, our hair cells cannot grow back.

What sounds cause NIHL?

NIHL can be caused by a one-time exposure to an intense “impulse” sound, such as an explosion, or by continuous exposure to loud sounds over an extended period of time, such as noise generated in a woodworking shop.”

The sheer amount of harmful noise situations we are exposed to is growing daily. Just think about the volume that your MP3 player, iPhone or Blackberry smart phones are played at, and how long you have those in-ear speakers in your ear canal…

“Sources of noise that can cause NIHL include motorcycles, firecrackers, and small firearms, all emitting sounds from 120 to 150 decibels. Long or repeated exposure to sounds at or above 85 decibels can cause hearing loss. The louder the sound, the shorter the time period before NIHL can occur. Sounds of less than 75 decibels, even after long exposure, are unlikely to cause hearing loss.”
