I found this derivation of the wave equation for sound waves:
http://www.pha.jhu.edu/~broholm/l28/node4.html
It seems rather straight forward in comparison to the one in Feynman's. Is there a problem to it e.g. is there anything wrong in taking the acceleration as the second derivative of the s-coordinat while working in x-coordinates for the medium?
