Speed of sound depends on temperature, not pressure

Evidence

Thus the speed of sound in air is dependent only on the square root of the absolute temperature, which can be obtained by adding 273 to the Celsius temperature; thus the speed of sound in air at 0°C and 20°C is: 1. — David Howard, Jamie Angus, coustics and Psychoacoustics, 65 (#corroborates, via linked claim)
