How Fast does Sound Travel?

The speed of sound is affected directly by the medium it travels through (meaning what’s in its way) and factors affecting the medium. More simply put, the speed of sound in air is determined by the air itself. More specifically by humidity, altitude, and temperature. To calculate the speed of sound in dry air at sea level, use the following formula V = 331.4 + 0.6Tc (V = Velocity (m/s), Tc = temperature in Celcius).
