You need to think a little more about the above statement. It is incorrect. Air travels at different speeds through different mediums, so thick walls and thick stage matter could have a slight effect on when the sound arrives to the audience, and how. The speed at which the sound travels has absolutely no effect on pitch. You can listen inside a refrigerator. You can put on scuba gear and listen underwater. You can put the sound into a telephone and send it electronically at essentially the speed of light to loudspeaker on another continent. None of this will have and effect on the frequency when the sound reaches the listener. It will effect the _delay_ between source and receiver, but not the frequency of the sound. The temperature of the medium affects the pitch as well, so it's very well possible that the temperature off stage could be very different from on stage, due to hot lights, etc. Every time I can remember being under a stage or off stage, it was much colder than on stage. It is only the temperature of the air in the oscillating instrument that affects frequency. Once the sound is emitted from the instrument, the temperature of the medium through which it travels has no effect on frequency. _______________________________________________ post: [email protected] unsubscribe or set options at https://pegasus.memphis.edu/cgi-bin/mailman/options/horn/archive%40jab.org
