how exactly is NIHL (noise induced hearing loss) caused including how it effects the insides of the ear?

---

i need a scientific answer that is possible to understand but still scientific. Does it break the ear drum? how does it make you lose your hearing?
The ear has 3 main parts. First is the outer ear which includes the outer ear canal (the portion u stick a qtip in). Then there is the middle ear which includes the eardrum and the 3 tiny ear bones, called ossicles. The third portion is the inner ear which contains the cochlea and nerves.

Ok- now to get to the main bulk of your question: when you listen to loud music, tiny hair cells in the cochlea of the inner ear are damaged, causing permanant hearing loss. The eardrum is not damaged. However, it is possible for it to burst as a result of infection-- but not loud sound. So these tiny hair cells located I the cochlea of the inner ear are supposed to be flexible and loud sounds damage them by stiffening them.

That is a very simple way of explaining it... But I know a lot about this and can give more info or details or explain it differently if needed. Good luck.  (+ info)

Noise induced hearing loss - Who knows the solution ?

Temporary threshold shift occurs for 24 hours after noise exposure... it comes back.
Longer duration NIHL may take 6 months to stabilize after exposure. After that, it is permanent.

How close are we to eliminating this?

I was performing for a musical and I didn't even realize until it was too late that the crash cymbal I was right next to was killing my right ear. Now my balance is slightly fucked up and it's really depressing me.

What truth is there to the statement that off-balance hearing is detrimental to pitch perception?

Would it be unwise to start protecting only my right ear for a little bit, as in if I went to a concert to only plug my right ear? Would this make my imbalance worse since the noise loss would be caused by a different frequency?

are there any famous people with noise-induced hearing loss?

---

I would imagine so. Noise induced hearing loss comes from exposure to loud sounds so although I don't know for sure, I bet that many famous people (especially musicians who frequent concerts) have noise induced hearing loss...or anyone who shops at Abercrombie.  (+ info)

I am looking for a clinical research study to participate in on noise induced hearing loss, can anyone help?

Are you near a teaching college? Try there. Also, check with a doctor that specializes in hearing problems.
Good luck :)  (+ info)

What can't I hear with 4000hz noise induced hearing loss?

---

I had a hearing test just today and the doc said I have a 10dB loss at the 4000hz mark (other than that I have better than normal hearing), but I forgot to ask him what that means I can't hear. I don't notice any hearing loss when talking to people, except for (and this is my second question) when there is background noise, such as power tools or music. Even if the person speaking is louder than the noise, I still can't understand them. Why is that? It can't be normal as people call me deaf when that happens.
Okay 10 dB hearing loss is very minimal hearing loss especially if it is only at 4000 Hz. However, 4000 Hz does carry a lot of speech information. So yes in quiet you probably hear find due to the minimal hearing loss, but in noisy situations it will be harder for you to hear and understand speech. Typically hearing loss at 4000 Hz is due to noise exposure. So you need to protect your hearing when around noise as much as possible wear earplugs when around concerts, target shooting, power tools, mowing lawn etc. People are ignorant and one day they will have the same problems.  (+ info)

I believe you're right about your ears trying to heal. That must have been horrible! Give it a few days and if you still have the problem see your doctor.  (+ info)

Noise Induced Hearing Loss?

How long does it actually take before your ears are damaged from loud music on an Ipod if you listen to it regularly full blast? I mean so it causes permanent tinnitus and not just temporary?
Once all the tiny hairs inside your ears are damaged i.e laying down, then that is it! they can never recover and your hearing will never repair itself, it doesn't take much pounding to start deteriorating, even hours, however if you stop damaging them now, you can keep the hearing you have, and that's it!  (+ info)
