The only thing that will "STOP" sound from propagating
is mass. Be it lead sheets in front of your ears, or a
ton of air between you and the source (note a ton of
air at atmosphere will take up lots of room and put you
far away from the source) or the same weight of
fiberglass as the lead between you and the source
(without any openings or holes).
Absorption as noted below is frequency dependant. Don't
expect what a 703 panel does to your cymbals to be as
dramatic for the kick. Bass needs lots o mass to be
Without building a room in a room you will only be
cutting the sound down some in the high end and very
little in the bass. Expect no more than 12 - 18dB STC
and even less in the bass.
Sorry there is not cheap and easy way to do this.
