Ar­les­heim Cathedral

Optimizing the sound system

Arlesheim Cathedral is an outstanding example of rococo architecture in the Basel region. The cathedral also has a Silbermann organ in near-original condition.
Unfortunately, the cathedral PA system left something to be desired and an analysis of ways to rectify this was commissioned. Acoustic measures were ruled out because the existing conditions are ideal for music, especially the organ.
Measurements and simulations of the current situation were carried out to analyze different options. Results showed that a substantial improvement could be achieved by making some low-cost adjustments (new amplifier, new microphone, loudspeaker overhaul) to tide the cathedral over until the planned general refurbishment, when speaker quality is to be greatly enhanced through new line arrays.
