The reference level of ones soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not difficult to 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 residential installation, quite often we find bedrooms and other living areas to be right next to your home cinema environment. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors generally been the weakest point, in type of attempt. The mass, damping and stiffness of the home cinema door determines its resistance to your passage of any sound waves. A door’s ability to relieve noise is offered by 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 pain. And to top it off, a tiny hole in a barrier would transmit almost as much sound as a much larger golf hole. This acoustic property of sound could be a significant problem in a residential cinema installation, where high quality construction is required. That is where acoustical gaskets come into play. 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 grade of of the acoustical gasket in a home cinema installation, would figure out how close the particular sound performance of the door, stomach to the published specification. A hi-end Home Cinemas Hertfordshire cinema design should take every detail into consideration, to ensure a hi-end acoustical stem.
