Churches are difficult spaces to predict due to several factors:

1 – surfaces are quite reflective and cause uncertainties on the aborption coefficients of the materials being used.

2 – churches are spaces that require specific acoustical conditions, both
comfortable for speech as well as the practise of music. Often very directional speakers
are used in such spaces which are impossible to use in typical prediction models.

The image above show 3D models of spaces we have studied at our company.

Using CATT we can studied different parameters and predict which is the best acoustics for a room, both for speech and music specifications.
