Acoustic Doors - Sound Resistant Doors In the age of open floor plans and chiming cell phones, silence is golden. That may explain the growing demand by architects and building owners for sound resistant doors. Acoustic doors are engineered to prevent a specific amount of sound from passing through a door. They have been common in loud environments such as manufacturing facilities and music studios for decades, but they have become increasingly popular in office buildings, hotels, and schools too. A door’s Sound Transmission Control (STC) rating specifies how much sound would be prevented from passing through the door. The higher the STC rating, the more sound resistant the door.
