Speak for yourself deafman! But don’t feel bad …my Fiancee is only 24 & can’t hear it unless she’s abut 20cms from it. Similarly most of my friends can’t hear them.
I’m pushing 30 and buzzing transformers, screaming capacitors (in Fluro lights) and dying monitors drives me up the wall.
Cheap cd/DVD players also produce nasty squeals, and any TV left on, with no signal make my brains dribble out my ears, or at least make me want to hit people.
Since I’m very relaxed in everyday life, my reaction to ongoing high pitch squeals makes me wonder whether it could be produced & focused and cause the residents of a city/suburb tear eachother to shreds.
I think Tom Clancy wrote about something similar in one of his op-centre books.
And can you imagine what all these “inaudible” watermarks in music tracks is gonna do … in public places, you can’t turn off the radio!
And won’t someone please think of the children! And the animals, which have much better hearing than humans!
