speed of sound

speed of sound
The speed at which the sound waves travel in a given medium. In the ISA (international standard atmosphere), sound travels at 761.6 mph (equivalent to 1116 ft/s, 340 m/s, 661.7 knots, 34,046.16 cm/s, or 1225.35 km/h). The speed of sound is determined by the density of the medium. In air, it is the temperature that affects the density and thus the speed of sound. See sonic speed.
