The reference level found in a 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 a residential installation, quite often we find bedrooms and other living areas to be right next to the home cinema room. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.
However, doors have always been the weakest point, in this 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 lessen noise is offered by its Sound transmission Class. This means, the higher within the Class the better the efficiency.
One more problem arises though; Sound waves can traverse any opening with very little impairment. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as a much larger target. This acoustic property of sound could be an oversized problem in your property cinema installation, where high quality construction is required. Can be where acoustical gaskets come into play. A Home Cinemas St Albans cinema door, to be able 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 house cinema installation, would figure out how close specific sound performance of the door, will come to the published standard. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical stem.
