Reverberation Enhancement in the Modal Sound Field
The reverberation time of a room can be increased by using a reverberation enhancement system. These electronic systems have generally been installed in large rooms, where diffuse field assumptions are sufficiently accurate. Novel applications of the technology can be found by applying it to smaller spaces where isolated modal resonances will dominate at low frequency. An analysis of a multi-channel feedback system within a rectangular enclosure is presented. To assess the performance of this system, metrics are defined based on the spatial and frequency variations of a diffuse field. These metrics are then used to optimize the parameters of the system using a genetic algorithm. It is shown that optimization significantly improves the performance of the system.
