Reverb |

Late Lat. reverberatio – reflection, from lat. reverbero – beat off, discard

Residual sound that persists after the complete cessation of the sound source due to the arrival of delayed reflected and scattered waves at a given point. It is observed in closed and partially closed rooms and largely determines their acoustic qualities. In architectural acoustics, there is the concept of standard R. time, or R. time (the time for which the sound density in a room decreases by 106 times); this value allows you to measure and compare the R. of the premises. R. depends on the volume of the room, increasing with its increase, as well as on the sound-absorbing properties of its interior. surfaces. The acoustics of a room are affected not only by the time of sounding, but also by the course of the decay process itself. In rooms where the decay of the sound slows down towards the end, the intelligibility of speech sounds is less. The R. effect that occurs in “radio” rooms (sounds from distant loudspeakers come later than from near ones), called. pseudo-reverb.
