Speed of sound doesn't depend on altitude (or air pressure), but on the square root of temperature expressed in Kelvin degrees (Kelvin = Celsius + 273), multiplied by a constant. With a temperature of 20 degrees Celsius (293 degrees Kelvin that is) the speed of sound is about 340 meters per second.
