Sound-proof cabins protect workers from noise in industrial workplaces. They are being used when a room has many machines that emit a loud noise inside. Shielding these machines would be combined with high costs. Cabins can be also used when there’s few people working in room, and their job is connected with controlling machines. Sound-proof cabins should be used as control rooms, control machinery rooms, technical services room, leisure rooms for workers. Cabins are being made from same materials and in a similiar way to the sound-proofing cases. Cabins have their ventilation. Our cabins can provide acoustic proofing as high as 35 dB.
