Noise and generators
In addition to plugging up all the holes, you
should make sure that the surfaces surrounding the noise source are soft (not hard and reflective) and bumpy. For instance if you have a cement block wall that is unpainted, it will be better than one that is painted because the paint fills in all the holes and reflects the noise back into the room. I've heard of fero cement hulls, but concrete block????? What sort of mortar do you use? What shape hull can you build? ;-) |
