Notice: The speed of sound changes with temperatureand

a little bit with humidity − but not with air pressure (atmospheric pressure).

The words "sound pressure at sea level" are incorrect and misleading.

The temperature indication, however, is absolutely necessary. The speed of sound in air at 20 degrees Celsius (68 degrees Fahrenheit) is 343 metres per second. That is 1126.547 feet per second. The speed of sound speed in air is determined by the air itself. It is not dependent upon the sound amplitude, frequency or wavelength.
