The reference level of ones soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not challenging to listen to, in a correctly designed home cinema room.
A problem occurs though, when we face the challenge of keeping prospective inside the cinema room. In non commercial installation, quite often we find bedrooms and other living areas to be right next to your home cinema residence. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors have always 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 offered by its Sound transmission Class. This means, the higher inside Class the better the efficiency.
One more problem arises though; Sound waves can cross any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit almost as much sound as being a much larger leak. This acoustic property of sound could be a big problem in a small cinema installation, where high quality construction is required. In the area where acoustical gaskets come into play. A home cinema door, in an effort to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, the grade of of the acoustical gasket in a house cinema audio visual installation Hertfordshire, would determine how close the actual sound performance of the door, will come to the published requirements. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical conclude.
