The reference level of 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 non commercial installation, quite often we find bedrooms and other living areas to be right next to the home cinema nursery. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission on the adjacent rooms.
However, doors have always been the weakest point, in such an attempt. The mass, damping and stiffness of the home cinema door determines its resistance towards the passage of any sound waves. A door’s ability to cut back noise is given by 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 pain. And to top it off, a tiny hole in a barrier would transmit almost as much sound as being a much larger emergency. This acoustic property of sound could be an appreciable problem in a small cinema installation, where high quality construction is required. Which is 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 grade of of the acoustical gasket in a place cinema installation, would figure out how close a lot more sound performance of the door, will come to the published requirements. A hi-end Home Theater Installation St Albans cinema design should take every detail into consideration, to ensure a hi-end acoustical result.
