Why does change in atm pressure not change the velocity of sound?
Asked by scholar1 | 09 Aug, 2009, 08:11: PM
Expert Answer

At a constant temperature, the pressure has no effect on the speed of sound, because pressure and density have equal but opposite effects on the speed of sound, and the two contributions cancel out exactly.
