Acoustic rehabilitation of middle twentieth century portuguese churches
Description
This paper analyzes two Catholic churches in Portugal (Our Lady of Conception in Porto, and Our Lady of Assumption in Santo Tirso) with acoustic problems related with a very long Reverberation Time and poor speech intelligibility. Both were built in the middle 20th century with a large reverberant interior (volumes of 10,000 and 12,500 m3). The results of in situ acoustic measurements are presented and also compared to those of other Portuguese churches with similar volumetric dimensions. Proposals for the acoustic rehabilitation for each church with a short cost analysis are presented.
