Increasing panel compression levels, or making a panel less prone to deformation by compression (dense hard close grain wood, laminated panel, or epoxied) will make the assembly stiffer under bearing load, but I don't see any reason to assume the panel gets stiffer under compression. >Even if compression and stiffness >are not synonymous in this discussion, then the question is does >compression itself change the physical and acoustical properties of the >panel? > >David Love Physical properties? Yes, it crushes the cellular structure. Acoustical properties? I don't have any way of ascertaining that one way or another. Ron N
