Most people over 20 turn deaf to the high 18-20khz frequencies.
A teenager can still hear that. So you wll be looking at a frequency of at least 25 khz.

A device called a mosquito was developed to chase away teenagers hanging around shopping malls. It works on the same principle!!!!!!!!!!!!!!!!!!!

sometimes headphones improve particular frequencies so as which you will pay attention particular sounds greater effectual on them than by using your conventional audio gadget. It additionally may be, finding at this kind of headphones which you have, that it quite is helping to cancel a number of the exterior 'room' sounds. that's my concept on what may be occurring.
