Abstract
The two methods of reverberation enhancement; assisted resonance (AR), a frequency divided system, and multiple channel reverberation (MCR), a space-divided system, are previously discussed mostly as methods of increasing reverberation time. The influence on sound intensity level, on sound distribution, and on impulse responses may be of great importance and will be discussed on the basis of accepted room acoustic criteria.
