Heat and Sound: Two Different Energy Fluxes, the Same Mathematical Treatment?
Every building is designed to shield human beings from the external environment, where not only climatic events but also phenomena produced by humans ( such as noise) may occur even people do not like them. At the basis of a proper building design there is the knowledge of the rules that allow us to foresee how and how much heat and noise cross the domestic walls. These rules start from two different ( but not so much) equations dealing with the same phenomenon: diffusion. It is shown here that it is possible to develop a unique theory for both the problems, apart from the original difference that frequency is an active reaction of matter inherent only to pressure waves in elastic media.
