This paper reports on an example of a data base for church acoustics. The initial scheme of data base fields is presented, including relationships to store the minimum information possible, to derive the required acoustic parameters automatically. It is demonstrated that if cross-data tools are added to the data base, it may also serve as an investigation platform from which results can be obtained which will allow acoustic patterns to be set depending on the volume and the internal architectural style. This hypothesis has been tested with Baroque churches, and a formula is proposed to predict the reverberation time, depending on the total volume of the room.
