Floors and ceilings can be soundproofed using many of the same systems suitable for walls.
Building a room within a room soundproof.
The thickness of existing walls plus the soundproofing of the acoustic booth.
The soundproofing of the building i e.
The flexible springy channels create.
Room within a room the next level of isolation comes from adding an air gap of at least 2 between the walls and ceiling in your studio and the surfaces surrounding it fig.
Building a room within a room casual noise can be reduced to a tolerable level by simply beefing up existing walls floors and ceilings.
Most soundproofing is done with the room within a room principle in mind.
Remember the room must be self contained.
The modular room aims at two effective factors in order to achieve good soundproofing from the inside to the outside and in the opposite direction.
At this point you re building a room within a room.
Construct a separate room within the original building with minimal contact.
The simplest way to soundproof a small space within a room is to build a solid concrete wall.
If space allows run a new wall of high density concrete blocks internally mounted on thin neoprene a type of synthetic rubber compound so that the blocks are not directly on the floor.
Method 1 the ideal design for a room within a room is to start off with a large enough solid walled building then constructing one or more inner rooms that should be self contained built on a floating floor and should not touch the main outer shell of a house.
Double layers of drywall are common for the inner room s walls and green glue noiseproof compound is used to seal the drywall.
In principle the aim is to reduce disturbing sounds in buildings.
It will have better results if it is not in contact with the shell of your house.
As a simple additional step cover the floor with soundproofing mats then install carpet.
The room within a room is also likely to use acoustic dampening insulation such as a the aforementioned roxul rockboard.
However if you want to achieve significant sound isolation then a dedicated room construction is in order.
