The reference level about a 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 instantly inside the cinema room. In residential installation, quite often we find bedrooms and other living areas to be right next towards the home cinema environment. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors have always been the weakest point, in an attempt. The mass, damping and stiffness of the home cinema door will determine its resistance to the passage of any sound waves. A door’s ability to reduce noise is available from 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 claim. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as being a much larger leak. This acoustic property of sound could be a significant problem in a small cinema installation, where high quality construction is required. Which is where acoustical gaskets come into engage. A home cinema door, to be able to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, the standard of of the acoustical gasket in a house cinema installation, would figure out how close the actual sound performance of the door, will arrive to the published requirements. A hi-end Home Cinemas Hertfordshire cinema design should take every detail into consideration, to ensure a hi-end acoustical stop result.
