Odd question - what frequency is this sound?

I've recently developed extreme sensitivity to specific frequencies of sound. The most blatant example in my day-to-day life is the sound of dishes clinking together. Like for example putting them away in a cupboard, the sound of them hitting each other just rips through my skull.

I'd like to figure out approximately what frequency range this sound is, and see if I can get any hearing protection that filters just that band of frequencies. Short of recording the sound and analyzing it (which I can do but will be some hassle), I thought maybe someone here might just know off the top of their heads roughly what that frequency range is.

Anyone? Thanks!

not really sure but that does not sound good.... I would get it checked out... could be the start of hearing problems or perhaps an infection of some kind.... I would guess it's somewhere between 8000 and 12000.
I get the same thing from hitting a wood block thingy.

All over the spectrum actually But yeah, very prominently in the fletcher-munson areas :/ Anything you can stick in your ear should put these down but if you want to know what frequencies to protect yourself from just do the "torture test" and sweep a loud sine and see where it hurts...

Anyway, that sound also hurts my ears.. Its the sudden burst nature that doesn't allow the ear to protect itself.

Interesting, thanks for the info. This is a recent and sudden change though... this type of sound has never bothered me before, but sometime in the last 6 weeks or so, it kicked in and is simply torturous now. I'll try the sinewave test and see if I can isolate a frequency that's the real killer.

Depends on the nature of the sine sweep, will the sweep take into account the fact that your ears are naturally more sensitive to the mid-frequencies (1-4kHz)?......Noise Induced Hearing Loss tends to affect that same region, your sensitivity could be a symptom of that or other things....if you're really concerned I'd recommend an audiometry test

and... I'm not quite sure the sine test will take into account the percussive nature of the sound...
like I said... wood block does it for me... a sharp brief pop that kills my ears... and I have some ear issues

Here's a frequency plot of the "average" (over 30 seconds) of 4 different plates clicking together (from my kitchen) recorded with a test microphone. I'd agree that the transients are a big contributor to the pain factor, and as such sweeping a sine may not trigger the specific reaction that the plates trigger.



Most of the big stuff shows up between 1-5 kHz, and it varies with each plate (this is an average of a 30 second long recording). This is the classic "hurt" frequency range for many folks, btw, with 2.5 kHz being at the heart of the range. :-)

Damn, that even looks painful with those 1, 2, 2.75, and 3.5K spikes
