The cabin (20) has walls (32-38) that are air-tightly formed and/or filtering circulation of air flowing through the walls. Articulations and closures are air-tightly placed with joints (44) of the walls, and connect the walls in an air-tight manner in an unfolded use position of the cabin. The folded up articulations allow superposition of the walls to each other in a transport position of the cabin. Weight of the cabin is less than or equal to 25 kg, preferably 23Kg. The walls are made from foamed material such as PVC foam. An independent claim is also included for a sensory analysis system.
