Fixing Hall Echo Without Scaffolding
4:35
A community hall's reverberation cut from 1.3s to 0.85s using nothing but curtains, a carpet runner and seat pads -- fittable by volunteers from a stepladder.
An illustrative worked example: a 16 x 10 x 6.5m single-storey community hall (1,040m3) -- brick walls, parquet floor, exposed roof trusses -- at 1.3 seconds reverberation against a brief-set target of 0.8-0.9s.
No budget for scaffolding…
