Ventilation facilities in the studio

In order to eliminate the heat generated by lighting and other equipment in the studio and the smoke generated when using smoke during filming, studios are equipped with ventilation and exhaust equipment. However, the vents, return air vents and exhaust vents of the ventilation equipment affect the sound insulation of the recording studio at the same time. Therefore, mufflers and anechoic chambers should be installed in the ventilation ducts to reduce the noise from the ventilation room; anechoic chambers should also be installed at the return air outlet and exhaust outlet to prevent the intrusion of external noise.
