As the son of an electrical engineer, I have always wondered what concept "impedance" was supposed to convey when used as "soundboard impedance". He tried his best to show me how electrical impedance was measured and used in formulas. So you can see why I have always been expecting formulas for sound board impedance. So not even knowing what the concept is, How can I think of a better term. There is that school of science that says in effect, if it can't be measured, you don't know what you are talking about. I think they really say if it can't be measured it can't be defined, which is the same as existance for them. This I think came out of the arguments for and against the concept of "the ether", the hypothetical medium for electromatic radiation like air is for sound. So a perfect problem for the "emperical" (measuring) scientists would be, "does humidity affect frequency of tones, or any part of the frequency of tones?" ---ric
