Sound Isolation
Jon Dansby
transmitted between floors? Our student ministry is soon moving into a
building where groups with full bands will be meeting upstairs and
downstairs. How can we best isolate the sound on each floor so that the
noise from each of our meetings don't bother each other too much. The floor
in the upper room is concrete, but bass does bleed through. In fact, the
bass is the main problem that must be addressed.
I have been looking at things like mass loaded vinyl as a solution. We could
lay it on the floor under the carpet in the upper room. I also need to know
what kind of price I'm looking at. What if the room is like 75' x 75'? What
kind of cost and options would be best?

Hi JD,
A difficult challenge.
Other than considering separate layers of concrete of dense flooring and
walls, isolated rooms within rooms, isolated by industrial springs and dense
rubber systems, lead etc...
What you're trying to achieve is similar to trying to have no vibrations
transmitted to a unit below from, say, a 6 foot section of telephone pole
being dropped vertically onto a concrete floor above, the ceiling of the
unit below.
Looking at it that way, you will appreciate that not hearing (feeling...!)
anything in the suite below is a difficult challenge.
Additionally, rooms with right angles and hard surfaces opposite each other
compound standing waves.
One thing to research recording studios that are faced with this challenge.
Consider posting also at rec.audio.pro, and look around at

I would put them in separate buildings.
Others here will have additional advice.
Bon chance.

to attenuate. It takes mass, and lots of it. Be aware that most sound
products are rated in STC units -- which typically drastically overstate the
amount of bass attenuation.

Ask these people if ENKASONIC® might be appropriate as part of the
solution of your problem.

Prevent it from ever getting to the floor, i. e. a floating floor.

You need a qualified acoustic consultant, it will in all likelyhood be
the cheapest in the long run.

If it was machinery one would try to use local vibration insulation, i.
e. a partial floating floor the bass instruments are on, preventing
direct vibration transmission MAY help, and it is cheapish trying.

At best an inefficient way to use money in the context of bass
attenutation.
Kind regards
