Are we talking about the same c? I thought it was the speed of sound.

Equation (2.19) on page 22 of Acoustics by Leo Beranek.

c^2 = gamma Po / rho

c is the speed of sound. This expression can be expressed a variety of ways by substitution of different variables.

And aplogies to everyone for being grouchy. I have a sore spot from all the uninformed opinions/explanations I used to read and believe before I got an engineering education.

That comes across loud and clear. However, in my opinion after having participated in a two discussion with you I could easily make the case you fit your own description of what creates a sore spot. Please don't over estimate your own knowledge and underestimate the knowledge of a lot of people on this forum. Sometimes having only one rigid definition or equation shuts off the possibilty of approaching a problem from an entirely new angle that advances your thinking. Having an engineering degree does not automatically make one correct in every technical discussion. Sometimes somebody with out any technical education or degree has a vision into a problem that is far ahead of all the engineers, they just understand what is happening and know the solution. I have tremendous respect for people with that kind of insight.

Martin,

"Please don't over estimate your own knowledge and underestimate the knowledge of a lot of people on this forum. "

I certainly try not to, and I'll say that it's apparent that svante (savant? ) is more knowledgeable on the topic than I.
