WebThe speed of sound is constant in the same sense that the mass of an object is constant. In the typical audible range, at frequencies below, like, $100\:\mathrm{kHz}$ and sound pressures much less than atmospheric pressure, the behaviour of air is very well described by a simple linear wave equation that's purely second order in both space and time WebIn non-humid air at 20 degrees Celsius, the speed of sound is about 343 meters per second or 767 miles per hour. We can also watch the speed of sound of a repeating simple harmonic wave. The speed of the wave can again be determined by the speed of the compressed regions as they travel through the medium.
