- Nope, it is the other way around. The resonate frequency is increased.
- Sound travels faster through solids and liquids than it does through
- the air.

- : By the way, the last number I saw for the speed of sound at mean sea
- : level is 1150 feet/sec.

- At STP - true.

- This was discussed, to some length, a year or so back. It is all
- based on experiments done by the French, around the time of the
- First World War, involving using low frequencies as a weapon on
- the battlefield. They found they could generate the lethal waves,
- the problem being that they are non-directional - so the person
- operating the equipment was also killed, along with the intended
- victims.
