•Acoustic absorption is tested by placing absorbing materials in pieces.•At low and medium frequencies there is no statistically significant relation.•A statistically significant relation is found in high frequencies.•A law is given to predict the absorption increase in terms of surface occupation.
We present the results of tests performed in a reverberation room measuring reverberation time with different acoustic absorbent materials in different layouts, compared to those results where the same material was 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. The analysis also prove the sturdiness of the model.
