Both have a basement, with separate walls, but on ground level, there is only one wall between old house and extension.
The floor touches that wall (see drawing).
My problem is that Room A, B and C are sleeping-rooms.
Room A and B are my children's rooms, and Room C is my parents' room.
There is a little noise coming to any of those rooms through the walls.
It's not much (like a TV in the next room, or someone talking in front of the door), but it keeps you in those rooms from sleeping.
The noise is certainly not coming through the hallway, and stairways.
Some details about the Durisol bricks:
These bricks are "composed of specially graded raw wood shavings and chips, which are neutralized and mineralized, then bonded together with Portland cement".
These bricks are hollow, and are filled with concrete.
Imagine cement-blocks, made of minarlized wood chips.

The floors and ceilings are made of reinforced concrete.
My band plays Death Metal (but we rehearse at very low volume, especially for that style
![Smile :)](./images/smilies/icon_smile.gif)
We can only rehearse in the evening.
Here's the questions:
How can I minimize the noise in Rooms A, B and C?
Is it best to do something about the ceiling of the rehearsal room? There's not much room to work with (only about 10cm)...
Or should I do something about the walls?
Only the wall with the door is finished with plaster, the other walls are untreated.
Oh, and the solution should be cheap...
Please help!
