Our band rehearses in a miners welfare hall. The hall is about 15m long, 8m wide and 8m high. It has a balcony over one end of the hall (it used to be used as a cinema). The walls, ceiling and floor are all hard surfaces. The acoustic is very 'wet', ringy and friendly to the band and can hide problems with ensemble. We have tried playing under the balcony, which is about 5 m long, 8m wide and 3m high (the band just fits), which gives a slight improvement but we really need to make the acoustic 'drier'. We think that we would be able to improve the acoustic by carpetting the floor and screening off the area under the balcony from the rest of the hall. Anything we use must be portable and easy to install as other groups also use the hall. Has anyone any experience of using screens for this purpose? Or has anyone any other suggestions which might help us to improve the acoustic?
