Quoted from chalkup8:I've always been conscious and a little concerned about outside pinball noise.I just don't want the neighbours or people walking by to know I got games.It might attract unwanted attention when no one's home.They know of the games,but lets see what other stuff might be there for the under the arm taking.
Hanging rugs on walls and laying them on floors helps deaden the sound/noise.I envy the basements some of the US pinsiders have.
Hope you can find a solution you're happy with.
The basement is a luxury I know I take for granted. The pins can be cranked up with subs on each one and the neighbors hear nothing. Earth is a bread sound killer.
