This parameter represents the speed of sound. This is the true airspeed of a sound wave in the air at a given temperature. Air in general is compressible. When a disturbance produces a small pressure change at a certain point (like your vocal chords), this pressure change will propagate through the air as a pressure wave at the speed of sound.
The following methods are used by this program to calculate the speed of sound:
Where is the speed of sound at sea level under standard conditions.
