If the mach number is >> 1, the flow speed is much higher than the speed of sound - and the speed is hypersonic. A subsonic wave is a wave that is traveling slower than the speed of sound and a supersonic waves travels faster. Search by City and State. Best Answer: Since the actual speed of sound varies from 1150 to 1180 fps for most places in the US - nobody shoots at 1130 sea level and stays dry - it also does vary depending altitude, temperature, and barometic pressure - most subsonic ammo is made to shoot about 1000 fps to provide an adaquate fudge factor between summer and winter shooting from sea level to mountain ranges.
