This is a simple way of expressing non-linear scales (such as decibels) in python. In stead of:gain = 10 ** (12/10.)Use Platforms: Windows, Mac, *nix, Python, BSD Solaris

A still atmosphere attenuates sound as a function of frequency, temperature, relative humidity, and propagation distance. This function uses equations published by Bass et al. to calcuate the attenuation of sound for the input parameters. The function returns the attenuation in decibels. Platforms: Matlab
