On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit 15 degrees Celsius — is Because gas molecules move more slowly at colder temperatures, that slows the speed of sound; sound moves faster through warmer air. Therefore, the speed required to break the sound barrier decreases higher in the atmosphere, where temperatures are colder. Scientists are interested in the speed of sound, according to NASA, because it indicates the speed of transmitting a "small disturbance" another way of describing a sound wave through a gas medium. The transmission of the disturbance takes place as molecules in the gas hit each other.

The speed at which sound propagates or travels from its source is referred to as the Speed of Sound or SOS. The speed of sound is directly influenced by both the medium through which it travels and the factors affecting the medium, primarily temperature and humidity for gases like air, and additional material properties for media such as liquids and solids. Variations in the speed of sound in air are caused by certain conditions of the air itself e. To calculate the approximate speed of sound in dry air, use the following formula:. A more accurate formula is:. This formula indicates that the speed of sound in air is proportional to the square root of temperature. Chuck Yeager is credited with being the first person to "break the sound barrier" by exceeding the speed of sound in controlled flight while piloting the Bell X-1 rocket plane pictured here on October 14, Being a dimensionless quantity, the word "Mach" traditionally precedes the actual measured value, similar to "mark twain" for depth soundings though if you are from Boston or Down East, these two measurement scales might be pronounced quite similarly.

In general, transverse waves occur as a pair of orthogonal polarizations.

The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. It depends strongly on temperature as well as the medium through which a sound wave is propagating. The speed of sound in an ideal gas depends only on its temperature and composition. The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior. In colloquial speech, speed of sound refers to the speed of sound waves in air.

This speed of sound calculator determines the speed of sound in the air and water. Not everybody knows about the sound speed dependence on the temperature — the higher the air temperature, the faster the sound can propagate. Did you notice something interesting? The humidity of air also has an effect on the speed of sound, but the influence is so small that it can be neglected. The temperature is the only important factor!

In a non-dispersive medium , the speed of sound is independent of sound frequency , so the speeds of energy transport and sound propagation are the same for all frequencies. The same phenomenon occurs with light waves; see optical dispersion for a description. The transmission of sound can be illustrated by using a model consisting of an array of spherical objects interconnected by springs. Kilometer per Hour Value:. Sound will travel more slowly in spongy materials and faster in stiffer ones. Note that the speed of pressure waves depends both on the pressure and shear resistance properties of the material, while the speed of shear waves depends on the shear properties only. The speed of sound on Mars varies as a function of frequency. Hence, it is possible to generate sound waves with different velocities dependent on the deformation mode. Since one speed of sound is equal to 1, The velocity in kilometers per hour is equal to the distance in kilometers divided by time in hours.

In other projects. That stands as the fastest speed achieved to date by a jet-powered aircraft. At altitude, for reasons explained, Mach number is a function of temperature. For audible frequencies above Hz it is relatively constant. Car heat Calculator The hot car calculator shows how fast a car's interior heats up during a summer day. Toggle limited content width. Reverberation Retrieved Speed of sound and kilometers per hour are both units used to measure speed. This produces a positive speed of sound gradient in this region. Higher frequencies travel faster than lower frequencies. She is one of a handful of Canadian reporters who specializes in space reporting.
