Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.
However, doors continually been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door determines its resistance for the passage of any sound waves. A door's ability to cut back noise is given by its Sound transmission Class. This means, the higher within the Class the better the efficiency.
One more problem arises though; Sound waves can travel through any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit almost as much sound as being a much larger golf hole. This acoustic property of sound could be a big problem in a home cinema installation, where high quality construction is required. Which is where acoustical gaskets come into play. A home cinema door, in order to be effective, the seals around the head, jamb and sill must be complete and air-tight.
