The reference level about 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 household installation, quite often we find bedrooms and other living areas to be right next to the Home Cinema Installation Hertfordshire cinema environment. Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors have always been the weakest point, in type of attempt. The mass, damping and stiffness of the home cinema door will determine its resistance towards the passage of any sound waves. A door’s ability to reduce noise is given 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 loss. And to top it off, a tiny hole in a barrier would transmit nearly as much sound like a much larger leak. This acoustic property of sound could be a big problem in a building cinema installation, where high quality construction is required. In the area where acoustical gaskets come into play. 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, exact same of the acoustical gasket in a home cinema installation, would see how close real sound performance of the door, will arrive to the published requirements. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical conclude.
