Church acoustics measurements and analysis

The measurement of Reverberation Time (RT) is a quite important estimation of the sound quality in a closed environment. From this measurement, in fact, one can gain information about intelligibility of signals and amount of reflection energy. In particular the liturgical hall of a church is an interesting environment because of its relevant volume and the materials adopted for the interior design. In this paper the authors present an experimental study of a new built church, in which the geometry of two lateral chapels produces interesting acoustical effects. A correction of the RT is proposed in the last part of the paper, by means of absorbing panels insertion. The intervention has been dimensioned, tuned and designed in a predictive software framework.
