How can temperature affect the speed of sound?

The speed of sound in air changes clearly with temperature, a
little bit with humidity − but not with air pressure (atmospheric
Statement: The static air pressure p_ and the density ρ of air (air density) are proportional at the same temperature, because the ratio p_ / ρ is always constant, on a high mountain or even on sea level altitude.
Notice: The ratio p_ / ρ (static air pressure to air density) is really always constant.
