Talk:Acoustics/Sound Speed

The paragraph below is IDIOTIC

"The speed varies depending on atmospheric conditions; the most important factor is the temperature. The humidity has very little effect on the speed of sound, while the static sound pressure (air pressure) has none. Sound travels slower with an increased altitude (elevation if you are on solid earth), primarily as a result of temperature and humidity changes."

Note the blatent contradictions:

Contradition 1:

"The humidity has very little effect on the speed of sound"

contradicts with

"Sound travels slower with an increased altitude.....primarily as a result of .... humidity changes." absolutely IDIOTIC!!!

Contradiction 2:

"the static sound pressure (air pressure) has [no effect on speed] & [humidity has very little effect]"

contradicts with

"Sound travels slower with an increased altitude [but the main effect increased altitude is pressure change]primarily as a result of temperature and humidity changes."

so the contradictions are:

humdidity has very little effect, except at high altitude in which case it has a huge effect. pressure has no effect - except if you reduce the pressure and temperature and change the humidity in which case it has a huge effect.....

someone needs to fix this!!!!!
