The reference level about a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not tough listen to, in a correctly designed home cinema room.
A problem occurs though, when we face the challenge of keeping regular alarm inside the cinema room. In a residential installation, quite often we find bedrooms and other living areas to be right next to the Home Theater Installation St Albans cinema environment. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission into 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 will determine its resistance for the passage of any sound waves. A door’s ability to reduce noise is given by its Sound transmission Class. This means, the higher inside Class the better the efficiency.
One more problem arises though; Sound waves can traverse any opening with very little impairment. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as a much larger target. This acoustic property of sound could be a significant problem in a residential cinema installation, where high quality construction is required. In the area where acoustical gaskets come into engage. A home cinema door, in an effort to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, exact same of the acoustical gasket in an at home cinema installation, would see how close the particular sound performance of the door, will come to the published list of specifications. A hi-end home cinema design should take every piece of information into consideration, to ensure a hi-end acoustical result.
