Sound Frequency

Fri Feb 17, 2006 5:18 pm

Last night on British TV a device emitting high pitched sound waves to drive under twenty nuisances away from shops was demonstrated.

Over twenties cannot hear the soundwaves which sound very much like personal alarms when amplified. So much for audio experts. We oldies haven't got a chance.

I remember my son asking me about some background music on an Album in the 70s and I couldn't hear it. NOW I know why. Our ears get less sensitive after the age of twenty!

I now get a hissing in my ears listening to CDs so what has changed from listening to Elvis on Vinyl :lol:

Poor ol' Ludwg Van Beethoven!

I heard that Colin!!!

My mother does not hear anything without her 2 hearing aids due to having had too strong eardrops who burned holes in her ears when she was 3 years old. Because she needs very powerfull hearing aids, she has to pay a lot of money for them herself. The ones covered by health insurance are no use to her.
So be carefull with your hearing. It saves a lot of nuisance and a lot of money when you get old!

Luuk, Thanks for the warning. My hearing is's just the slight hiss that's always there now......... a minor problem compared to others, like your Mom.

If our hearing changes at about the age of twenty that means youngsters hear the best of all versions of Elvis now.

Our crackling Elvis HMV 78s were treasures nevertheless :)
