My mother-in-law's voice?

Answer 2

I've tested a few of those ultra-sonic repellers that claim to repel mosquitoes, and haven't been able to discern any measureable repellent effect whatsoever.

There is a high pitched frequency that is apparently easily heard by teenage humans, while inaudible to most of us old fogeys who damaged our ears with Led Zeppelin on our Walkmans back in the day.

I have confirmed that I can't hear that frequency at all, but it drives my sister-in-law insane.

I love that sound - I often play it on a loop on my computer in the background whenever she's over.
