has anyone ever that expression before or "Stop making that sound, it`s putting my teeth on edge".

 

things like the Skrrreeeeeeeeeeeeeeeech when finger nails go down a blackboard, or rubbing polystyrene together.

it seems to make some people go crazy, almost as if the sound hurts them?

they will cringe, or shout at you, and at the very least not want you to do it again!

 

what causes this?

It feels Obnoxious. Maybe there are some pitches involved that we cannot hear. Someone probably has the real info...

I find it`s also interesting that not everyone has the same triggers.

the person that does the nails down the blackboard seems largely unaffected for instance (I`ve done it myself and it doesn`t bother me).

but getting a bread knife to cut sheets or blocks of polystyrene gives me shivers and I hate it (even thinking about it). what the hell causes it? LOL

There are certain things that I can't stand touching. It's a similar feeling. I hate drinking from paper cups, or paper drinking straws. I also don't like eating peaches with the furry skin. It might be a different response though, just with a similar obnoxious result.

 

Pincho.

I used to get a similar effect from the paper used in old blue print machines. it felt sort of powdery and wuold go a bit shiny if scratched, just touching that stuff gives me the creeps and I have no logic reason WHY!? and that in itself annoys me as much as the darn paper does/did

i know what ya mean, well did. the shiver that gets sent up your spine from that sort of thing......i dont get it anymore though, wonder were it went?

I had the same response to the blue copies from hell. I also hate to touch frosted glass.

 

I have no problems with polystyrene regardless of what you do to it (within reason ) but I hate fingernails on on blackboard. The reason is that I imagine the feeling of my fingernails dragging along the slightly rough surface {shudder} it's not the noise it's the thought of doing it.

 

I had a friend at school who really reacted badly to the blackboard torture. He came in one day with a pot filled with chili pepper, mustard and all sorts of other hot things. He slugged it back and the effect of the concoction of hot spices allowed him to drag his fingernails up and down the blackboard like a man possessed.

 

So, either hot condiments are a cure or (and I think this is more likely) my friend was just a madman.

lack of a spine as a result of being an evil demonic skull might have something to do with it.

i have a great a powerful spine muhahahaha, i thought it was more to do with just hearing it to much to not care about it anymore......sorta induced immunity

And so...

 

does anyone have any idea why it`s called "Teeth on edge" and what causes this effect?

maybe Glider will know? but all ideas are welcome

"set [one's] teeth on edge" comes from a piece by shakespere but this phrase also apperars in the bible, specifically the book of Jeremiah.

it used to be a description of an irritation i.e radical edwards eye sets my teeth on edge, gradually it just got to be known as the description as we all know it by today

Maybe the sound intensity and frequency is too high?

These descriptive meanings usually have a truth to them, and this thread is to find out where the true meaning comes from. You can imagine your teeth recieving a high frequency wave, like glass can be broken by a high frequency wave. Some people say "It gives me the judders." It can create a muscle reaction. That's another odd reaction to a sound, of feeling. Music can make your spine tingle, another strange sensation. Teeth on edge, is much harder to define though. Can anyone explain it?

Well, styrofoam actually makes my teeth feel like they are being cut in half, front to back... that is probably where the name came from.

It's not that.  People use funky little oscilators all the time and don't have any sort of response to it.  It probably has to do with the pitch, but not just because it is high.  More likely it is because of more than one high pitch at the same time, some sort of sound pattern that is different for every person.

it`s possibly a combination of sounds thinking about it. in polystyrene each little particle (or ball) will make a small squeek when cut, 100`s of them all a little different wouldn`t be deep (rich) enough to make white noise, but certainly a bad combo and not in "tune" I mention tune deliberately because if any of you have experienced the sound of a Violin in the hands of a beginner, will know what bad tune sounds like!

it would be interesting to see what the most irritating sound would be, take a sound bite of it, amp it up to a few 100db and use it for an Alarm system

It seems to trigger a defense mechanism perhaps? It's hard to understand why a defense mechanism would be triggered in this situation though.

I agree, what are we deffending ourselves against?

it`s clear that no harm will come to us from hearing it.

maybe it`s an evolution thing? perhaps that sound or something similar meant some kind of danger in cave man days, or maybe something from childhood AHA! whilst typing this idea occured, could it be something with Dentists and drills or the sound teeth make when they rub together before they come out (baby teeth)?

just a thought

Never heard a similar sound apart from the drill. Maybe the drill triggers the fear? I've had my teeth scraped, and it's not nice, not a nice sound either, but not high pitched.

I never had the prob before about the age of 9(ish).

and the blue copies were the only thing available then, I`de often cut cardboard with a knife and polystyrene, never had an issue with it. this just gets more and more baffling all the time

I never had a problem with paper straws until I got a piece of wood in my foot when I was about 8. Now I find it hard to touch unvarnished wood, and a lot of paper objects. The blackboard thing wouldn't really be likely to happen until you are about 9 simply by statistics. What I mean is, you have to be at school, and it's not likely to happen right away.

 

Pincho.

What gets ME is getting soap under my nails. Or anything else that's in small pieces.

Oh yes, and when someone screeches the chalk on the board.

are you a chick? (no offense) nails and all that sounds like a chickish thing (not a baby turtle either)

Just proof that skulls do not possess brains.

anyway........

do we know what causes this yet?
