air absorption calculator

This calculator displays two functions in accordance with ANSI S1.26-1995. Firstly, attenuation by air absorption for all frequencies for a single point in space based on distance, temperature, relative humidity and atmospheric pressure. Secondly, the attenuation value from temperature versus relative humidity, for a single frequency.

features:

  • in accordance with ANSI S1.26-1995
  • 3 frequency responses (48 points-per-octave)
  • normalization
  • cut-off frequency (-6 dB)
  • attenuation: temperature vs. relative humidity
