Un'ipotesi psicoacustica per la percezione spaziale del suono basata su parametri energetici

A psychoacoustical frame for the spacial hearing impression is here proposed. The frame is based on energy parameters of a general acoustic field such as the Active Intensity, Reactive Intensity Amplitude and the Energy Transfer Velocity, which are briefly introduced and interpreted from the point of view of human spatial perception of sound. It turns out that the space-related sound attributes are well represented by a perceptual continuum between two idealized acoustic situations: the plane progressive wave field and the stationary wave field. The analogy of human hearing system with the p-p method for sound intensity measurements is also suggested.
