Abstract
Abstract A sound enhancing system for either an open or a closed auditorium includes a reverberation chamber positioned above the ceiling of the shell from which said sound originates. Speakers within the reverberation chamber receive low frequency signals from microphones in the shell. The reverberation chamber has an opening in the wall facing the audience through which sound can pass.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
A system for improving the fidelity of sound emanating from a stage and directed toward an audience positioned in front of the stage comprising a reverberation chamber positioned above said stage, said reverberation chamber having a first wall facing the audience and a second wall facing said stage, at least one loudspeaker in said reverberation chamber, at least one microphone above said stage for receiving sound emanating from said stage, means connecting said microphone with said loudspeaker for delivering amplified sound from said microphone to said loudspeaker, an opening in said first wall for delivering sound from said reverberation chamber to the audience and an opening in said second wall for acoustically coupling the sound produced in said reverberation chamber with the sound emanating from said stage.
Claim 2
Independent Claim
127 words
A system for improving the fidelity of sound emanating from a stage and directed toward an audience positioned in front of the stage comprising a reverberation chamber positioned above said stage, said reverberation chamber having a first wall facing the audience and a second wall facing said stage, at least one loudspeaker in said reverberation chamber, at least one microphone above said stage for receiving sound emanating from said stage, means connecting said microphone with said loudspeaker for delivering amplified sound from said microphone to said loudspeaker, an opening in said first wall for delivering sound from said reverberation chamber to the audience and an opening in said second wall for acoustically coupling the sound produced in said reverberation chamber with the sound emanating from said stage.
Claim 3
Dependent Claim
72 words
A system as defined in claim 1, wherein said system comprises a plurality of loud speakers in said reverberation chamber and said means includes time delay means so adjusted that a signal from said microphone reaches each of said plurality of loud speakers in sequence, the time delay between the output of said signal from said microphone and the energization of each successive loud speaker in response to said signal being adjustable.
Claim 4
Dependent Claim
22 words
A system as defined in claim 2, wherein the minimum time delay introduced is zero and the maximum is about 300 milliseconds.
Claim 5
Dependent Claim
41 words
A system as defined in claim 2, wherein said means further includes level control means so adjusted that the level to which each successive speaker is energized in response to said given signal is lower than that of the preceding speaker.
Claim 6
Dependent Claim
28 words
A system as defined in claim 1, wherein said means and said loud speaker is designed for amplification and transmission of frequencies from about 30 to 250 Hz.
Claim 7
Dependent Claim
27 words
A system as defined in claim 1, wherein said second wall is composed of panels spaced-apart and oriented to reflect sound from said stage to said audience.
Claim 8
Dependent Claim
27 words
A system as defined in claim 1, wherein said speaker is located above any line of sight from the audience through said opening in said first wall.
