What Does a Notch in Hearing at 4 kHz Indicate?

[Hariz Nonis]

The hearing is fine. I have hyperacusis to the 4k frequencies when I get exposed to industrial noise. The other day, for example, was bothered by a leaf blower that was droning on from 5 houses away. It was not loud and <70 db, but still damn annoying and needed earplugs just to tolerate it outside while I had some work to do in my garden.

Is there any other sound from any other frequency that gives you discomfort/pain?

Interestingly, it does not. Just that industrial noise seems to be the bothersome one.

It wouldn't be bothersome if there were not previous trauma to your ears in that frequency range. Sorry. Just make sure to keep protecting your ears and maybe it will lessen.

You are absolutely correct, and that is what is fascinating to me. Yes, I keep protecting when there is potential for this type of exposure as I am quite a bit sensitive to it. Even if it is way up the street, I can hear that industrial noise from the lawn crews with their equipment, and it drives my ears crazy pretty quickly.

Otherwise, I am quite thankful as my T has reduced quite a bit, and am having more good days with it than bad days at this point, and it does not keep me up at night.

Let's just say I've not been doing enough to protect my ears from whatever sounds it could be sensitive to. If I start now, it could still lessen, right?

Yes. It would also help to prevent further damage.

4K notch is industrial sound exposure, such as lawn mowers, leaf blower, passing cars, factory noise, and the like. My understanding is that it does not prove NIHL, but is suggestive of it from the sources above.

NIHL can be asymmetric depending on the exposure. In my case, I got T in one ear without the other as that was the side in retrospect that the weed wacker was on. I protect both ears the same at this point to prevent any further issues.

Would this be considered noise induced ?

 

[Digital Doc]

Not an expert on this, but I believe the notch goes down further for a 4k notch. Still, your audiogram would be consistent with noise damage.

What the the audiologist performing the test indicate?

Yours seems to be better than mine. Do you have T?

I know you're asking the other guy, but the ENT doctor from my most recent appointment said that my hearing is fine. I did a second hearing test, and my 4kHz notch on my right side is still at 30 dB. However, my 8kHz on my right side went from 5/10 dB to 0 dB. That was an interesting find.

Yes, low constant tone in my right ear. Intermittent in left...I have had it since feb9, 2019. How about you?

Nevwer gave me any real info

What caused it?

I don't really have T now. It's just some form of Middle Ear Myoclonus that I'm going through. Although, it seems to be affecting my hearing in some way.

Damn annoying. When they can't sell a hearing aid too many of them lose interest.
