How many of you can hear this? I can here it quite well, and its very piercing.

I recall in a physics class, the teacher used a tone generating program to show us the differences. It was very interesting. He adjusted to various levels and did an informal poll of who could hear it.tnf wrote:No, but I'm glad this thing came out...it will be handy as another example when I'm teaching sound and the hear.
We discuss how the range of frequencies you can hear diminishes with age, now I've got a nice useful demonstration.

Wierd, I can hear it when I do that, it's bloody quiet otherwise, 36. I'm assuming that this means it's not somethng that you suddenly stop hearing but instead a frequency volume that gradually decreases with age?duffman91 wrote:Yeah, without turning my volume up ridiculously high, I can't hear it.YourGrandpa wrote:I can hear it. It's just not that loud.

argh-- it's the noise CRTs and old TVs make. Quite irritating indeed.
Edit: hahah- a bit of ear/jaw manipulation and I was able to make myself not hear it.
I basically opened my mouth wide, and the sound vanished.
Not like "say ahhh" open, I mean using your jaw and stretching open. A yawn I suppose. :icon14:
I thought it was cool
....can't seem to do it anymore. :/

No, its the result of the loss/damage of hair cells lining the inner ear. Think of these kind of like tuning forks that resonate with a specific frequency and end up sending signals to the brain. When they are damanged, you lose ability to hear the frequencies the damaged cells would sort of resonate with.
