I had a challenge in a 95 sqm size kitchen/family room with the acoustics. This room is always full of people cooking, watching tv, doing homework, rollerblading, talking etc.
The room: build with painted dry walls and a tiled floor
The problem: To much noise bounsing around the room, no one can hear or think straight.
The solution: Artificial grass on the rear wall.
Problem solved and it looks really cool to
