The reference level of a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not difficult 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 audio visual installation Hertfordshire, quite often we find bedrooms and other living areas to be right next to the home cinema residence. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.
However, doors have been been the weakest point, in this 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 inside the Class the better the efficiency.
One more problem arises though; Sound waves can travel through any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit almost as much sound being a much larger emergency. This acoustic property of sound could be an appreciable problem in a small cinema installation, where high quality construction is required. Which is where acoustical gaskets come into game. 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 an at home cinema installation, would see how close specific sound performance of the door, will come to the published order. A hi-end home cinema design should take every piece of information into consideration, to ensure a hi-end acoustical conclude.
