In the center of the room is a surface plate, and towards the back is an exhaust smoke device for automotive exhaust mufflers. The exhaust smoke device utilizes flexible ducts, allowing the device to be moved to the position of each vehicle model’s muffler.

Regarding ventilation and air conditioning, all are designed for soundproofing. For this facility, silencers are designed for air conditioning, ventilation, and exhaust, with ventilation pathways provided both inside and outside the semi-anechoic chamber. This allows for acoustic measurements even when each air conditioning and ventilation device is operational.
