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 a residential installation, quite often we find bedrooms and other living areas to be right next on the Home Cinemas Hertfordshire cinema room. Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors have always been the weakest point, in 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 relieve noise is written by its Sound transmission Class. This means, the higher up 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 being a much larger hole. This acoustic property of sound could be a big problem in a small cinema installation, where high quality construction is required. That’s the where acoustical gaskets come into play. 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 actual of the acoustical gasket in a real estate cinema installation, would determine how close specific sound performance of the door, will arrive to the published standard. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical stem.
