For example, the speed of sound in air is 386 m/s at 100 °C. The sound of speed in air is increased by 0.60 m/s for each increase of degree in air temperature. The speed of sound is faster at higher temperatures because molecules collide more often.

Doing this calculation for air at 0°C gives vsound = 331.39 m/s and at 1°C gives vsound = 332.00 m/s. This leads to a commonly used approximate formula for the sound speed in air:

NPL Acoustics: Calculation of speed of sound in humid air ... The calculator presented here computes the zero-frequency speed of sound in humid air according to Cramer (J. Acoust. Soc. Am., 93, p2510, 1993), with saturation vapour pressure taken from Davis, Metrologia, 29, p67, 1992, and a mole fraction of carbon dioxide of...

Measuring the speed of sound in air. ... Speed of Sound in Air ... There are a number of ways to measure the speed of sound in air. Some use simple equipment, and others use computer- or calculator-based technology. A common, non-technical method uses a tuning fork to set up resonance in a column of air.

Sound travels faster through warm air than through cold air. This is to be expected because the faster-moving molecules in warm air bump into each other more often and therefore transmit a pulse in less time. For each degree rise in temperature above 0 degrees C, the speed of sound in air increases by 0.6 meters per second.

acoustics FAQ: What is the speed of sound in air, water .. ? ... The speed of sound in air at a temperature of 0 degC and 50% relative humidity is 331.6 m/s. The speed is proportional to the square root of absolute temperature and it is therefore about 12 m/s greater at 20 degC.
