Maximization of Reverberation Index.
Abstract
Investigations into the problem of maximizing array gain(DI) for situations where ambient noise is the dominant interference have been conducted over the preceding two decades and possibly earlier. These investigations have resulted in mathematical solutions having significant promise in various practical applications. A closely related problem arises when interference is dominated by reverberation; in this situation the gain against reverberation (the reverberation index, RI) must be maximized. The same general mathematical approach can be applied to both problems in that the omnidirectional ambient noise limited condition can be considered a specific case of the more general directional ambient noise limited condition and the reverberation limited condition. Much of the existing theory that has been developed has been directed at specific cases, thus leaving unfinished a comprehensive treatment of the general case. A concomitant existing problem involves the determination of the computational complexity involved in the mathematical solution to the described problems since this complexity strongly influences the degree to which computational methods can be applied to practical problems.
