We are in the process of designing renovations for a local Methodist Chapel. The building is also used by a famous local (and international) male voice choir. (for practice)
The ceiling of the building needs to be replaced and insulation added.
The problem: The choir is very worried about the work messing up the acoustics of the building. The ceiling is currently plaster laid on laths fixed to joists, about 150 years old. If we replace this with plasterboard, which is softer, will we spoil the sound?
Whatever we do will be wrong, (we realise that) but we would like to be less wrong. (if possible) .
Anyone tell me about acoustics of this type of roof. It is also sort of barrel vaulted but will be altered to flat.
Am I on a loser here?
