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.
Building a room within a room soundproof.
If you want this space to be incredibly effective have it built on a floating floor.
The room within a room is also likely to use acoustic dampening insulation such as a the aforementioned roxul rockboard.
The thickness of existing walls plus the soundproofing of the acoustic booth.
Remember the room must be self contained.
The simplest way to soundproof a small space within a room is to build a solid concrete wall.
Most soundproofing is done with the room within a room principle in mind.
One of the very best ways to soundproof a room is to install resilient channels which are z shaped metal strips that go between the wall studs and drywall.
In principle the aim is to reduce disturbing sounds in buildings.
Most commonly homeowners add an additional layer or two of drywall with dampening glue in between.
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.
Construct a separate room within the original building with minimal contact.
Building a room within a room casual noise can be reduced to a tolerable level by simply beefing up existing walls floors and ceilings.
As a simple additional step cover the floor with soundproofing mats then install carpet.
The soundproofing of the building i e.
Soundproof floors and ceilings.
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.
At this point you re building a room within a room.
Floors and ceilings can be soundproofed using many of the same systems suitable for walls.
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.
It will have better results if it is not in contact with the shell of your house.
