Hi everybody,

I've uploaded a calculator that I recently used to demonstrate the negligible effect of humidity on the speed of sound.

This calculator calculates the speed of sound based on temperature, relative humidity and altitude according to Owen Cramer's paper "The variation of the specific heat ratio and the speed of sound in air with temperature, pressure, humidity, and CO2 concentration" published in the Journal of the Acoustical Society of America.

The calculator is valid for temperatures from 0 - 30 °C (32 - 86 °F) and pressures from 75 - 102 kPa.

Metric and imperial units are displayed.

Enjoy!

Click here for the calculator.
