Aerospace | The speed of propagation of sound waves. In the atmosphere cs = [? (R*/M0)TM]1/2 where ? is the ratio of specific heat of air at constant pressure to that a constant volume, R* is the universal gas constant, M0 is the mean molecular weight of air at sea level, and TM is the molecular scale temperature.At sea level in the standard atmosphere, the speed of sound is 340.294 meters per second (1116.45 feet per second). The concept of the speed of sound in the atmosphere loses its applicability at about 90 kilometers where the mean of free path of air molecules approaches the wavelengths of sound waves.Symbol cs.

Physics | A)the distance travelled by a sound wave in unit time; b)a function of the elastic properties of the medium and the mode of propagation as well as thermodynamic variables such as temperature, pressure and density. Source: European Union. (references) |
Space | The rate at which sound waves travel. This is about the speed of 750 MPH. The air waves gather together to act as a force on the moving airplane. When the force is broken, the airplane is said to be breaking the. (references) |

(From Wikipedia, the free Encyclopedia)
The speed of sound varies depending on the medium through which the sound waves pass. It is usually quoted in describing properties of substances (e.g. see the article on sodium).
More commonly the term refers to the speed of sound in air. In this case the physical properties of the air, its pressure and humidity for instance, affect the speed. An approximate speed (in metres/second) can be calculated from:
A more accurate expression is
The speed of sound is typically measured given a "standard atmosphere". Under these conditions the speed of sound is approximately 343 m/s, or 750 miles/hour.
In solids the speed of sound is given by:
The speed of sound in water is of interest to those mapping the ocean floor. In saltwater, sound travels at about 1500 m/s and in freshwater 1435 m/s. These speeds vary due to pressure, depth, temperature, salinity and other factors.
