Soundproof garage door ideas?
Has anyone tried and succeeded with making their surburban garage door soundproof, so that workshop noise is controlled?
Maybe someone's tried plywood panels over the inside of the doors or similar.
Seems to be plenty information about other aspects of soundproofing (I particularly like the CSR 'External Noise Systems' brochure even though it is about noise getting in rather than out). But garage doors don't seem to be a thing that gets internet coverage.
There's plenty of stories on this forum about irate neighbours etc. but I'm really after practical ideas on noise reduction rather than lots of angry-neighbour stories; if that is possible.
