Abstract

Audio reproduction of a movie inside a not dedicated room is critical; setting an ITU 5.1 system at home, for example, requires to place a large number of speakers around the room. But positions of speakers are often conditioned by the furniture. Bad alignment reduces spatial performances of the system dramatically.
For circumventing the above problems, most stereo TV sets, nowadays, are equipped with some form of “virtual surround” reproduction, employing substantially the Stereo Dipole method. This provides a very good frontal sound stage, but indeed sucks regarding the emulation of virtual surround loudspeakers.
An alternative reproduction technique is PanAmbio 4.1, based on a double stereo dipole system (frontal and rear). In this work the authors propose a comparison between the standard 5-ways surround system, and the new one. Validation is performed by subjective tests inside a domestic room.
