Wavelength - Frequency Calculator

Sound is a vibration that travels through an elastic medium as a wave.
The speed of sound describes how far this wave travels in a given amount of time. In dry air at 20°C (68°F), the speed of sound is 343,2 meters per second (1,126 ft/s). This equates to 1,236 kilometers per hour (768 mph), or about one mile in five seconds.

What is the speed of sound in air?

The speed of sound changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure).
