Answer:

Air pressure has no effect at all in an ideal gas approximation. This is because pressure and density both contribute to sound velocity equally, and in an ideal gas the two effects cancel out, leaving only the effect of temperature. Sound usually travels more slowly with greater altitude, due to reduced temperature.

Factors Affecting the Velocity of Sound in a Gas

Effect of temperature.

Explanation:

It varies with altitude (height) only because of the changing temperature! The atmospheric pressure is proportional to the density of air. Therefore both values have no effect on the speed of sound. specific gas constant for dry air R = 287.058 (J/K·kg).
