Obviously air density matters as in vacuum sound would not travel, however in the troposphere and the lower stratosphere the effect is near nill. The air pressure and the density of air (air density) are proportional to each other at the same temperature.
Speed of sound in air and the temperature calculator. No air pressure table density of air calculation acoustic impedance air density - sengpielaudio
