Abstract: Preliminary measurements of the acoustic energy density, given by E = 12ρv2 + 12(p2 / ρpc2) have been made for pure-tone excitation of a large reverberation room. Measurements at eight independent positions in the room show a variation of approximately half that encountered when measuring p2 at the same positions. Additionally, average values of E obtained are close to twice the average values obtained for 12(p2 / ρc2), as predicted, and values of the standard deviation of p2 are very close to the average value of p2, also as predicted. Although the method used for the preliminary measurements was slow and laborious, instrumentation is presently under development which will allow the measurements to be made rapidly and inexpensively. Details of this instrumentation and proposed applications are discussed, together with additional data.
