The reference level of one soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not hard to listen to, in a correctly designed home cinema room.
A problem occurs though, when we face the challenge of keeping instantly inside the cinema room. In Home Cinemas St Albans installation, quite often we find bedrooms and other living areas to be right next for the home cinema room. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.
However, doors constantly been the weakest point, in such an attempt. The mass, damping and stiffness of the home cinema door will determine its resistance towards passage of any sound waves. A door’s ability to lessen 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 cross any opening with very little pain. And to top it off, a tiny hole in a barrier would transmit almost as much sound being a much larger hole. This acoustic property of sound could be a significant problem in a home cinema installation, where high quality construction is required. That’s the where acoustical gaskets come into game. A home cinema door, in order to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, exact same of the acoustical gasket in a place cinema installation, would determine how close the actual sound performance of the door, arrives to the published list of specifications. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical stem.
