1. An acoustic shell system for enhancing sound made by a performer in a performance area, the acoustic shell system comprising:
- a microphone positioned in the performance area to receive sound made by the performer;
a first panel having an acoustic reflective surface oriented toward the performance area;
a second panel spaced apart from the first panel, the second panel having an acoustic reflective surface oriented toward the first panel and an acoustic absorptive surface oriented toward the performance area to create a semi-anechoic zone within the performance area proximal the acoustic absorptive surface;
an electronic acoustic assembly operably coupled to the microphone for processing sound received by the microphone; and
a speaker operably coupled to the electronic acoustic assembly, positioned intermediate the first panel and the second panel, and oriented toward the acoustic reflective surface of the first panel to broadcast sound processed by the electronic acoustic assembly indirectly to the performance area.

Abstract
An electroacoustic shell system adapted create a performance area where sound created by a performer is received, processed, and returned to the performer in the performance area. The system broadly includes an electroacoustic shell with a vertical panel and a canopy, a microphone and a speaker operably coupled to the shell, and an electronics processing assembly connected to the microphones and speakers for recording, broadcasting, and simulating sound.

7. A method of enhancing sound made by a performer in a performance area of an acoustic shell system, the acoustic shell system including a microphone, a speaker positioned intermediate first and second spaced-apart panels and oriented toward the first panel, and an electronic acoustic assembly operably coupled to the microphone and the speaker, the method comprising:
-
creating a semi-anechoic zone within the performance area proximal the second panel; receiving, with the microphone, sound made by the performer; processing, with the electronic acoustic assembly, sound received by the microphone; and broadcasting, from the speaker indirectly to the performance area, sound processed by the electronic acoustic assembly. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. An acoustic shell system for enhancing sound made by a performer in a performance area, the acoustic shell system comprising:
-
a microphone positioned in the performance area to receive sound made by the performer; a first panel having a first acoustic reflective surface oriented toward the performance area; a second panel spaced apart from the first panel, the second panel having a second acoustic reflective surface oriented toward the first acoustic reflective surface and an acoustic absorptive surface oriented toward the performance area, the first acoustic reflective surface and the second acoustic reflective surface being opposed boundaries of a space between the first acoustic reflective surface and the second acoustic reflective surface; an electronic acoustic assembly operably coupled to the microphone for processing sound received by the microphone; and a speaker operably coupled to the electronic acoustic assembly, located within the space, and positioned to broadcast sound into the space, wherein sound processed by the electronic acoustic assembly is broadcast indirectly to the performance area.
