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 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 residential installation, quite often we find bedrooms and other living areas to be right next on the Home Cinemas St Albans cinema residence. Special room construction techniques allow us put together 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 the passage of any sound waves. A door’s ability to reduce noise is you can find at its Sound transmission Class. This means, the higher in the Class the better the efficiency.
One more problem arises though; Sound waves can cross any opening with very little claim. And to top it off, a tiny hole in a barrier would transmit almost as much sound as a much larger leak. This acoustic property of sound could be an oversized problem in a residential cinema installation, where high quality construction is required. That is where acoustical gaskets come into engage. A home cinema door, in order 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 installation, would determine how close real sound performance of the door, will come to the published standard. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical stem.
