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 typical inside the cinema room. In a residential installation, quite often we find bedrooms and other living areas to be right next for the home cinema environment. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission on 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 lessen noise is written by its Sound transmission Class. This means, the higher within the Class the better the efficiency.
One more problem arises though; Sound waves can cross any opening with very little harm. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as a much larger hole. This acoustic property of sound could be a significant problem in a small cinema installation, where high quality construction is required. Can be where acoustical gaskets come into have. A home cinema door, so as to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, the standard of of the acoustical gasket in a place cinema installation, would see how close the particular sound performance of the door, will come to the published order. A hi-end Home Cinemas St Albans cinema design should take everything into consideration, to ensure a hi-end acoustical stop result.
