Abstract: Method in which, primarily in listening rooms, instead of the particular environment's own spatial sound, the spatial sound of a third room may be given an enveloping quality in the perception of the listener. The third room spatial acoustics perceived instead of the listening room spatial acoustics act in the same way in terms of hearing physiology as the spatial acoustics of natural rooms. That is, enveloping in terms of the spatial sound (in a distinction from direct sound). This type of spatial enveloping effect may also be incorporated emotionally by the listener into the auditory event, and has no “sweet spot” problem (there is a large preferred listening area instead of a preferred listening spot) and allows low frequencies to act in such a way that use of subwoofer speakers may generally be dispensed with.
