The reference level of a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not hard listen to, in a correctly designed Home Theater Installation Hertfordshire cinema room.
A problem occurs though, when we face the challenge of keeping regular alarm inside the cinema room. In a residential installation, quite often we find bedrooms and other living areas to be right next on the home cinema nursery. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors constantly been the weakest point, in this kind 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 cut back noise is written by its Sound transmission Class. This means, the higher inside 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 nearly as much sound as being a much larger leak. This acoustic property of sound could be a significant problem in a home cinema installation, where high quality construction is required. Can be where acoustical gaskets come into have. A home cinema door, so that you can 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 house cinema installation, would see how close specific sound performance of the door, can come to the published requirements. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical end result.
