This calculation is usually accurate enough, but for great precision one must examine the more general relationship for sound speed in gases. This sound speed does not apply to gases other than air, for example the helium from a balloon.

Air is a gas, and a very important property of any gas is the speed of sound through the gas. Why are we interested in the speed of sound? The speed of "sound" is actually the speed of transmission of a small disturbance through a medium.

You can measure the speed of sound the same way you measure the speed of a runner, with a stopwatch on a closed track. ... The Speed of sound in water is 1480 m/s or 4856 ft/s. More than 3000 miles per hour.

The first analytical determination of the speed of sound was given by Isaac Newton in Proposition 49 of Book II of the Principia. For sea level air at a typical ambient temperature he computed a value of 979 ft/sec, which is too low by about 15%, the true value being about 1116 ft/sec. To account for this...

The Speed of Sound and Mach Numbers ... The Mach number (M) refers to the method of measuring airspeed that was developed by the Austrian physicist Ernst Mach. It is used to indicate flight velocities in high-speed flight and is related to the speed of sound.

Speed of Sound The important Air Temperature and the nonrelevant Atmospheric pressure (Air pressure) ... The speed of sound in air is determined by the air itself and is not dependent upon the amplitude, frequency, or wavelength of the sound. For an ideal gas the speed of sound depends only on the temperature and...

The speed of sound (otherwise known as Mach 1) varies with temperature. At sea level on a “standard day,” the temperature is 59°F, and Mach 1 is approximately 761 mph. As the altitude increases, the temperature and speed of sound both decrease until about 36,000 feet, after which the temperature remains steady...
