Church Acoustics

The speech intelligibilty in the Saint Blasius church has been a problem due to the shape (the dome in the center of the ceiling). The acoustics of the church has been investigated with and without sound reinforcement system. The structure of early sound reflection, the value of T60, C80, D50 and RASTI were measured. The problem has been solved by the design with combining system - with loudspeaker column directionally and distributed loudspeaker system.
