For what it's worth, there a implementation in the MATLAB file

Hello all,
A few days ago I posted a simple C function to calculate
sound absorption in air (reproduced below), adding that
the origin of this code was not clear.
Joern reported that it could have been [1]. That is not
the case, in fact it was the Javascript code at [2].
But comparing the two,
Hi, all,
According to the following paper, theh = r * powf (10.0f, C) / p should
be correct, where p = P_s/P_{s0}, the relative pressure.
