The reference level of a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not difficult to listen to, in a correctly designed home cinema room.
A problem occurs though, when we face the challenge of keeping the noise inside the cinema room. In home installation, quite often we find bedrooms and other living areas to be right next to the Home Cinemas St Albans cinema room. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.
However, doors generally been the weakest point, in type of attempt. The mass, damping and stiffness of the home cinema door determines its resistance towards passage of any sound waves. A door’s ability to relieve noise is written 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 pain. And to top it off, a tiny hole in a barrier would transmit almost as much sound as a much larger golf hole. This acoustic property of sound could be an oversized problem in a small cinema installation, where high quality construction is required. Which is where acoustical gaskets come into have. A home cinema door, so as to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, the quality of the acoustical gasket in a real estate cinema installation, would determine how close the particular sound performance of the door, arrives to the published requirements. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical conclude.
