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 regular alarm inside the cinema room. In non commercial installation, quite often we find bedrooms and other living areas to be right next towards the home cinema nursery. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.
However, doors have been been the weakest point, in this kind 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 reduce noise is given by its Sound transmission Class. This means, the higher within the Class the better the efficiency.
One more problem arises though; Sound waves can travel through any opening with very little claim. And to top it off, a tiny hole in a barrier would transmit almost as much sound like a much larger golf hole. This acoustic property of sound could be an appreciable problem in a residential cinema installation, where high quality construction is required. Can be where acoustical gaskets come into appreciate. 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, exact same of the acoustical gasket in a home cinema installation, would figure out how close the actual sound performance of the door, stomach to the published order. A hi-end Home Cinemas Hertfordshire cinema design should take everything into consideration, to ensure a hi-end acoustical conclude.
