What Is the Exact Speed of Sound?

Answer

The exact speed of sound, when measured at sea level at normal atmospheric pressure, is 340.29 m/s. Sound travels at different speeds depending on the medium; for instance in water that's 25 degrees Celsius, , the speed of sound is 1497 m/s and in brass the speed is 4700 m/s. Basically, the denser the medium, the higher the speed.

The speed of sound varies depending on the temperature, pressure, and density of the medium through which the sound waves travel. For dry air at sea level at 68° F, the speed of sound is 767 miles per hour, or 1235 km/h
The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. Sound travels at different speeds depending on what it is travelling through. Of the three mediums, gas, liquid, and solid, sound waves travel the slowest through gases, faster through liquids, and fastest through solids. In dry air at 20 °C the speed of sound is 343.2 metres per second.
