Speed of Sound in Air
C = 49.03 √460 + T in feet per second
= 20.05 √273 + Tc in meters per second
Speed of sound in feet per second
T = Temperature in degrees Fahrenheit
Cm = Speed of sound in meters per second
Tc = Temperature
in degrees Celsius
The temperature of air has a significant effect on the speed of sound. It is usually
assumed that the speed of sound is not dependent on frequency or humidity. Sound
travels much faster in solids than in air.
