What are some sounds that you just can't stand to hear?

Little kids screaming.
The sound of teeth scraping across the sidewalk.
Screeching tires.
The mufflers of those rice burner cars.
The timer going off at the massage parlor.

I can't stand the sound of those booming bass boxes in peoples cars ! They make my truck vibrate and drive my ears nuts ! I hate those things ! BOOM BOOM BOOM ! Barf !

I accidentally answered the wrong question before so I'll switch my response to here. Sorry!

That sound when fingernails are dragged across a chalkboard and those crotch rocket motorcycles as they are unnecessarily loud. Oh and rap "music."

The most annoying noise in the world...according to Jim Carry in Dumb and Dumber

The sound of two pieces of styrofoam being rubbed together and the sound of other people barfing.

The sound when two teeth slide over each other >.<

The sound of sliding nails over the wall : /

The sound of today's metal music (most) gives me nothing but a long headache. Sometimes i really wonder, really is there anyone to understand the lyrics & what the singer is telling ?!

Very loud screams

The sound of dishes & doors (if they hit heavily)

That weird sucking noise people make when trying to get food out of their teeth.

Harley Davidson low rumble.

Dentists drill.

Compressors.

Sirens.

People Arguing.

Cats in heat.

Dripping fawcet.

The bass beat of rap crap.

Not one of those people who play that garbage know anything about wave mechanics and how a loud bass noise can pass through many things treble and the other wave lengths can't.

The worst sound I ever heard was as I was going over the handlebars in a multiple bicycle crash, was the sound of somebody's head hitting the road. As it happened he was the only rider in the pack wearing a hard helmet, so it was fine -- but it sounded awful.

Rather comically (from a spectators point of view, anyway) he injured himself painfully in another, more personal part of his anatomy. He pleaded with us to take down his shorts and make sure he hadn't lost anything. Seriously. He was much relieved when we were able to confirm that all the dangly bits were still in place.

All rap.

Dentist drill.        Noises I like kitties meowing

A topfuel dragster idling getting ready to launch

A nasa space rocket lauching into the heavens

I can't stand when people whistle a tune it drives me mad, and especially if it wakes me up.

The thud and metal crunching when a car is in an accident.

A parent or other adult belittling a child.

The cry of a parent whose child has died. (It is different than any other mournful cry.)

Any animal whimpering in pain, but even more so if the animal belongs to me.

Loud trains , dogs barking, a ballon that pops!  Stuff like that.
