The reference level about a 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 the noise inside the cinema room. In household audio visual installation Hertfordshire, quite often we find bedrooms and other living areas to be right next to the home cinema environment. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors have been been the weakest point, in type of 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 reduce noise is available from its Sound transmission Class. This means, the higher up 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 nearly as much sound for a much larger leak. This acoustic property of sound could be an oversized problem in a building cinema installation, where high quality construction is required. Which is where acoustical gaskets come into engage. 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 quality of the acoustical gasket in a home cinema installation, would figure out how close specific sound performance of the door, will come to the published requirements. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical stop result.
