I don't think the natural frequency of the board, used as a drum, has anything to do with it. The sounds we hear from the board are forced frequencies. Usually, in my experience, the resonant frequency of the board doesn't cause a problem, but I think it can. For example I recently came across a new Wendl and Lung upright which seemed to resonate in a very noticeable way. Perhaps other can say whether the _absence_ of a deafened section might make such problems more likely? JD
