The reference level of ones 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 the noise inside the cinema room. In home installation, quite often we find bedrooms and other living areas to be right next for the home cinema nursery. Special room construction techniques allow us to build 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 for the passage of any sound waves. A door’s ability to lessen noise is available from 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 nearly as much sound being a much larger leak. This acoustic property of sound could be a significant problem in a residential cinema audio visual installation St Albans, where high quality construction is required. That is where acoustical gaskets come into game. 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 quality of the acoustical gasket in a home cinema installation, would determine how close specific sound performance of the door, arrives to the published specification. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical conclude.
