3pAA8. Determination of the reverberation time in any point of a closed room by a physico-mathematical model based on geometric acoustics.

Session: Wednesday Afternoon, December 4

Time: 3:45

Abstract:

The determination of the reverberation time in a model based on geometric acoustics, which uses acoustic pressure and particle speed represented by means of phasors as working variables, is presented. Let p[inf 1](centered dot)(centered dot)(centered dot)p[inf m] be the pressure waves that reach the receiver in orderly instances t[inf 1](centered dot)(centered dot)(centered dot)t[inf m], let p[inf 0] be the phasor sum of them; and let L[inf 0] be the corresponding equivalent level. The levels
