There are a vast number of microscopic sensory hair cells in the the Organ of Corti these hair are very fragile indeed and are easily damaged. In addition to these delicate hairs there are three tiny bones that vibrate and act as amplifiers, these amplifiers do a remarkable job when they are not under assault by excessive noise.
When the movement of the tiny bones in the middle ear vibrate the oval window of the cochlea, there are waves that are then created in the fluid surrounding the cochlea. These sound waves bend the basilar membrane in place corresponding to specific frequencies.
The hair cells in those places then brush against the overlying membrane causing the generation an pulse. It is this pulse which gets sent to the brain. The brain interprets those electrical pulses as sound.
When the tiny hairs and nerve endings become damaged as a result of exposure to excessive noise, high frequency hearing loss often results. So the obvious first line of defense limit the noise.
We have touched on excessive exposure to high levels of noise especially over a period of time. I think you might be surprised at how easily your life will get you into a hearing damaging circumstance. Fortunately much of this exposure to excessive noise will cause problems that fade in time once the source of the noise is removed. Below are some examples of potentially dangerous any day if not everyday exposures to the kind of noise we are talking about. I got these from a simple poll of my own family which includes a couple of high school and a college student. These exposures were experienced in just the last ten days. After you read the exposures that a poll of my own family from just the last month of their lives revealed I hope you will remember to avoid such risks and they will too.
- high school rally for the basketball team
- the game itself
- a party at a friend’s house
- attendance at a muscle car exhibition
- several rides on the NYC subway system
I am sure that if you sit with your family you could come up with a list of your own in no time.
Add to this that many have exposures like these added to a work environment that is excessively noisy and you have a lot of chances for damage to people’s auditory systems. If you are suffering anew from ringing on the ears from noise induced tinnitus do what you can to give the delicate instruments in your hearing system a rest from the assault.
In the event that this is the type of thing you may be experiencing your condition from I thought it might it would be helpful to let you have some information regarding cochlea damage resulting mostly from exposure to excessive or persistent noise.
I hope this gives you some insight into what actually happens when cochlea damage occurs as a result of exposure to noise.
This type of hearing loss will be either temporary or permanent depending on a wide variety of factors. See a physician if you think that you may have been impacted negatively by a noise.
