I am more struck by the absence of basic measurements of physics in this field. One problem that I have been working on is the extent of vibration especially in headphone cases and speaker enclosures. I have never seen one measurement reported as to how much there is, even though there is more than a passing interest in reducing this problem. Grado have a proprietary plastic they use with their phones to reduce vibrations, Sennheiser uses a polymer (probably sorbothane or something related) in some of its high end phones, we use spike under speakers and sorbothane footers and yet I have never seen a single measurement showing how much such things actually reduce vibration, let alone the more difficult measurement of whether people hear the effects.
It is not enough to merely wave around some theoretical explanation of a phenomenon, that is only speculation. You need evidence as to how these things actually work and as many here note that usually translates to measuring something.
