House a couple blocks away is home to a porfessional drummer. Has built a
practice room inside the garage. Totally isolated from the garage and
heavily soundproofed. You can barely hear him when the garage is open.


I knew a guy who saved (and had all his neighbors save for him) the egg
cartons that a dozen eggs came in at the store. This was back when they
were made of cardboard and not Styrofoam.
He stapled them to the walls, ceiling and inner door surfaces of his
practice room an apartment. Once he had all the surfaces covered, you could
barely hear him anywhere else.
