The construction has moved on to the acoustic room that will house pumps and compressors. This equipment creates a lot of noise and for that reason it should be isolated from the rest of the lab. You can see the walls made of special sound-proof material on the right. Fridges will be on the left and the pipes up by the ceiling will connect pumps to the fridges. The room has multiple doors, and each door will be sealed carefully along the perimeter.
