Abstract

The reverberation time of a reverberation room with an absorbent material is proved against different layouts of the material and with and without a combination of different back air layers, compared to those results where the same material is placed as a single piece. With the analysis of the obtained data, a regression model is established in order to predict, for certain frequencies, the improvement produced in the reverberation time of a room, using the same amount of material by placing it in pieces separated from each other, instead of in one piece, and including different distances from the wall as a variable. It becomes a simple on work predictive tool which allows to estimate the alteration in the reverberation time due to the separation of the patches. The model is validated and proven to be robust and it is shown to be applicable to a variety of materials.
