[TPIN] "volume recognition"

[Robert "Robbie" Robinson]

I don't know about the other questions, but there is a ringtone for cell 
phones available that only (mostly) younger folks can hear.  Thinking it was 
an urban legend, I downloaded it to my cell phone and when I played it as an 
experiment in front of some people, the younger kids could hear it but the 
older folks (all late 20s or older) could not.

So, anyway, the answer to your first question is, apparently, yes.  Younger 
people can hear higher frequencies than people in their 20s and older.  I'm 
not sure why, but if I recall correctly, it had to do with the aging 
process, and not necessarily with exposure to noise.

You can google "mosquito ringtone" for more information on that one.

I recently read that young people (15 and under?) can hear high pitched 
sound that they are unable to hear in their 20's and 30's.  Does anyone 
know, is this true for everyone?
What about someone who has never been exposed to loud sounds?  Would't they 
still have their ability to hear those high pitched sounds?
Another question: I know someone who has apparently had some low pitched 
hearing loss; is this common?
Can ringing in the ears be an indicator for hearing loss?
Final question for tonite:  how many of you use earplugs on a regular basis?
