The reference level of a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not tough listen to, in a correctly designed home cinema room.
A problem occurs though, when we face the challenge of keeping typical inside the cinema room. In a residential installation, quite often we find bedrooms and other living areas to be right next towards the home cinema home. Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission on the adjacent rooms.
However, doors have been been the weakest point, in an 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 given by its Sound transmission Class. This means, the higher in the Class the better the efficiency.
One more problem arises though; Sound waves can traverse any opening with very little claim. 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 a significant problem in a residential cinema installation, where high quality construction is required. Can be where acoustical gaskets come into play. 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, exact same of the acoustical gasket in a home cinema installation, would see how close specific sound performance of the door, will arrive to the published list of specifications. A hi-end Home Theater Installation Hertfordshire cinema design should take everything into consideration, to ensure a hi-end acoustical result.
