Definition of "reverbation"

In trumpets for assisting the hearing, all reverbation of the trumpet must be avoided. It must be made thick, of the least elastic materials, and covered with cloth externally. For all reverbation lasts for a short time, and produces new sounds which mix with those which are coming in.

MeNeCe will architectically present the whole sphere with: CENTRE (radialy[sic]-based structure). ENVIRONMENT (columnic-nestlike networks). PERIPHERY (divergenting and convergentic staphyline-clasteric structures), with described below structure for reverbation of the information in N-peaked nets (by analogy with human Short-Term Memory - STM).

The top one was measured in an office with a reverbation time of about 300ms. The middle one is the impulse response of the passenger cabin of a car (BMW 520) with a reverbation of about 60ms. In the lowest diagram the maximal echo reduction according to Eq. 6.76 is depicted.
