Always good to limit one's exposure to overly loud sounds.. but one must
also remember that there is natural loss of high frequencies as we age.
Teenagers are taking advantage of this fact now with their 17KHz ringtone,
which the average person over 30 cannot hear.

Not really. It shows that intensity effect percieved pitch and that
when
adding equal non reinforcing tones the results depart from what would
be expected.

What, to me at least, makes this even more interesting is the date the
research was published, Jan 1935.

In 1974 at college I took a course on the physics of music and musical
instruments. The course ignored the whole louder sounds sharp, softer
sounds flat issue.

I didn't go to the food store yesterday for food. (and beer,if I want
beer that bad,all I have to do is step over to the Exxon convenience
store/gas station about one block from me.I haven't had a beer in about
a week) I will go to the food store tomorrow though (and the discount
tobacco store) because I have just enough cigarette tobacoo to last me
about twenty four hours and the same with my mostly empty jar of
Folger's instant coffee.I can do without my beer,but I can't do without
my coffee.I tried that once before.

My hearing cleared up (mostly cleared up) a few days ago.

My electric fan running on the end table (it's warm enough in my house
to have my airconditioner turned on) by doggys end of her couch (looking
at the front of her couch,the middle and left end is her end) and
Katrina: The Long Road Back on NBC Radio tv.

The Long Road Back wouldn't be so long if the place wasn't infested with
filthy democrats. It'd be back to normal if people down there would just
get off their ass and work instead of whining.

You didn't watch national tv news or the talking heads on tv yesterday
and today? Mississippi Gulf Coast area people started rebuilding the day
after Katrina and are still rebuilding right now,everyday.We dont sit
around and cry like a bunch of crybabies and wait on fed govt handouts.
