The speed des sound zu sein a term used kommen sie describe the speed von sound waves passing through bei elastic medium.

Du schaust: Schallgeschwindigkeit in km h

The speed varies with the medium work (for example, sound tide move quicker through water than with air), and with die properties of the medium, specifically temperature.

The term is commonly used to refer particularly to ns speed von sound in air.

At sea level, at a temperature of 21 degrees Celsius (70 levels Fahrenheit) and under normalerweise atmospheric conditions, die speed des sound ist 344 m/s (1238 km/h or 770 mph).

The rate varies depending on atmospheric conditions; the most crucial factor ist the temperature.

Humidity has wenig effect on the speed of sound, nor does air pressure by itself.

Air pressure has actually no effect weist all in an ideal gas approximation.

This is because pressure and density both contribute kommen sie sound velocity equally, and in an ideal gas the two results cancel out, leaving only die effect des temperature.

Sound usually travels much more slowly with greater altitude, due to reduced temperature.
