Answer:
Wind can increase or decrease the speed, and can even push sound waves sideways. Air density affects it. Temperature, pressure, humidity and gas mixture can each affect the density. In liquid: The speed of sound is affected by density and viscosity

Explanation:
At a constant temperature, the gas pressure has no effect on the speed of sound, since the density will increase, and since pressure and density (also proportional to pressure) have equal but opposite effects on the speed of sound, and the two contributions cancel out exactly.
