<< Hi everyone,
I am semi-new to this list and am a little confused on how to send a
question/comment that everyone can see, so basically this is just a
test. I am a 9th grade clarinetist from FL if you really wanted to know.

Now Mark, I don't have an issue with the formulae regarding the
speed of sound changing, but pitch, being the time difference between
the peak and trough of the wave form is independent of the speed at
which the wave form arrives.

The time difference between the leading edge and trailing edge of
the wave form will be the same at the receiver as they were at the
sender, no matter how quickly or slowly they are transmitted.
(Assuming that the humidity and air temperature are the same at
the receiver as at the sender.) Pitch is simply a signal modulated
at the speed of sound.

If I sit three feet in front of you in a bus, I will arrive at our
destination still three feet in front of you regardless of whether
the bus travelled 25 mph or 60 mph.

Please excuse my broad terms, but acoustics is not my forte (so to
speak) and as such, these are my opinions about facts. However,
there are several volumes of Benade's works behind me on the
bookshelf in which I'm sure that I could find the real answer if
there were sufficient time.
