Why the speed of sound does not depend upon Pressure??
Why the speed of sound doesn't depend upon Pressure When it does depend on Density?
c =sqrt(gamma p/rho)
I honestly would've thought that higher pressures mean that particles are packed closer together, meaning that the wave would travel faster, but wikipedia says otherwise:
This appears to indicate that density doesn't play a role in things either... which really baffles me. It says humidity DOES affect it, so its definitely in. Put in or leave out density, it's up to you. Maybe someone more learned could clarify this?

The Attempt at a Solution
I honestly would've thought that higher pressures mean that particles are packed closer together, meaning that the wave would travel faster, but wikipedia says otherwise:
"Air pressure has almost no effect on sound speed. It has no effect at all in an ideal gas approximation, because pressure and density both contribute to sound velocity equally, and in an ideal gas the two effects cancel out..."
