Method and apparatus for controlling the sound field in auditoriums
First Claim
1. An apparatus for controlling a sound field in auditoriums having at least a stage area and a main audience seating area, comprising:
- a first assisted acoustics means comprising;
a first input means for inputting acoustic energy in the stage area;
a first control means for electrically controlling the acoustic energy input by said first input means;
a first output means for outputting the controlled acoustic energy of said first control means to the main audience seating area;
a second assisted acoustics means comprising;
a second input means for inputting acoustic energy in the main audience seating area;
a second control means for electrically controlling the acoustic energy input by said second input means;
a second output means for outputting the controlled acoustic energy of said second control means to the stage area;
wherein said first and second control means are controlled so that a power decay coefficient of the stage area and a power decay coefficient of the main audience seating area come to equal one another.

Abstract
A system for controlling the second field in auditorium having the feature that stage and audience seating areas are different acoustically, which includes a first assisted acoustics system whereby acoustical energy from the stage area is input, and then controlled acoustic energy is supplied to the audience seating area, and a second assisted acoustics which is provided independently of the first electronic acoustical augmentation system, whereby acoustical energy from the audience seating area is input, and then controlled acoustic energy is supplied to the stage area. Each assisted acoustics system includes acoustic energy input devices and acoustic energy output devices whereby a uniform rate of power decay coefficient can be effected throughout the hall, including spaces under balconies and the like. Significantly improved the degree of acoustic similarity between the stage area and audience seating area is achieved by controlling reverberation characteristics.
