What is the speed of sound at sea level in regual air pressure?
In m/s or mi/h. or what ever is easy.

At sea level, at a temperature of 15 °C (59 °F) and under normal atmospheric conditions, the speed of sound is 340 m.s-1 (1225 km.h-1 or 761 mph).(*)
It is important to note that the sound speed in air is determined by the air itself. It is not dependent upon the sound amplitude, frequency or wavelength.(**)

The speed of sound varies with temperature and pressure it's somewhere around 725 mph at sea level. unless I'm calling my kids to come in and do their homework then it takes a longer time to reach them for some unknown reason. I just checked at 100f it is approx. 793mph at sea level.

About 750 miles an hour at sea level, but it travels much faster when in the form of gossip moving through a crowd of women :-)

At 60 F speed of sound = 1117 ft/s
= 761.6 mph
= 340.5 m/s

Speed of sound = 331.4 m/s at 0 degrees C and increases 0.6 m/s for each degree above zero

It's about 600 mph.

Its about 331.0meters a second.
In water, its three times as fast.
