Patent ID: 7187777

Claim:
Apparatus for stimulating sound properties of audio sound reproducing equipment not physically present in a simulated environment not physically present comprising, a source of binaurally encoded audio signals processed for loudspeakers reproduction characterizing selected sound reproducing audio equipment including a loudspeaker system not physically present in a simulated environment not physically present, left and right electroacoustical transducers, a head locator constructed and arranged to locate a listener's head in a predetermined position a predetermined distance from said left and right electroacoustical transducers so that said electroacoustical transducers are forwarded of the listener's head, and amplifying apparatus coupling said source to said electroacoustical transducers, and a selector operable by a listener with head substantially at said predetermined position constructed and arranged to select the audio reproduced by said electroacoustical transducers to furnish that listener with a sound simulation of selected sound reproducing audio equipment including a loudspeaker system not physically present in a selected simulated environment not physically present substantially the same as if that listener were listening to the sound reproducing audio equipment being simulated in the environment being simulated and further comprising a booth containing said electroacoustical transducers, said head locator and said selector, wherein the interior surfaces of said booth are constructed and arranged to absorb sound furnished by said left and right electroacoustical transducers and prevent substantial reflection therefrom by a least one of absorbing sound furnished by said left and right electroacoustical transducers and allowing said sound to pass to the outside of the interior of said booth.
