The reference level of one 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 cinema room.
A problem occurs though, when we face the challenge of keeping the noise inside the cinema room. In residential installation, quite often we find bedrooms and other living areas to be right next towards the home cinema environment. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.
However, doors have been been the weakest point, in type of attempt. The mass, damping and stiffness of the home cinema door will determine its resistance towards passage of any sound waves. A door’s ability to reduce noise is written by its Sound transmission Class. This means, the higher in 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 as being a much larger leak. This acoustic property of sound could be a problem in a home cinema installation, where high quality construction is required. That’s the where acoustical gaskets come into engage. 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 actual of the acoustical gasket in a house cinema audio visual installation Hertfordshire, would see how close a lot more sound performance of the door, arrives to the published requirements. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical end result.
