A shrill sound is high pitched and sharp, like the squeak of the mouse in your cupboard or the sound of your “eek” when you hear it.

Closer to a shriek than a trill, a shrill tone is one that might make you cover your ears, usually because the tone is so high and sharp. A high pitched voice, a classroom of excited first graders, or the sound of chalk scraping the board can all be shrill, as can a color or light that looks as sharp and intense as a shrill tone sounds.
