Instruments in concert halls or in a rooms. The temperature indication, however, is absolutelyĬhanging of the air pressure does not change the sound of musical The words 'sound pressure at sea level' are incorrect and misleading in theĬase of 'speed of sound'. − but not with air pressure (atmospheric pressure). The speed of sound changes clearly with temperature, a little bit with humidity Notice for musicians and technicians (not for professors of physics): You will see the program but the function will not work. The used browser does not support JavaScript. Don't forget, this is a site for sound designers. The air pressure is entered here anyway, it could be that you have to involve a Even seemingly small percentage changes may cause serious listening This dependence also applies really good to air, in goodĪpproximation and can be regarded as an ideal gas.Įnvironmental effects change the speed of sound and the absorption of sound Gas the speed of sound depends only on its temperature and is independent Upon the amplitude, frequency, or wavelength of the sound. The speed of sound in air is determined by the air itself and is not dependent The standard air pressure (atmospheric pressure) is 101325 Pa = 101.325 kPa or 1013.25 hectopascal. In the region between the air pressures 95 and 104 kPa there is no noticeable changing of the speed of sound c. The calculator is valid over the temperature range 0 to 30☌ (273.15 to 303.15 K) and over the pressure range 67, 1992', and a mole fraction of carbon dioxide of 0.0004. 2510, 1993', with saturation vapor pressure taken from Richard S.

This calculator is to determine the speed of sound in humid or moist air (water vapor) according to OwenĬramer, 'JASA, 93, p. Speed of sound in humid air ( Relative humidity ).
