The reference level of one 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 residential installation, quite often we find bedrooms and other living areas to be right next to the home cinema residence. Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.
However, doors have been been the weakest point, in this 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 lessen 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 impairment. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as a much larger leak. This acoustic property of sound could be a problem in a home cinema installation, where high quality construction is required. Which is where acoustical gaskets come into engage. 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 place cinema installation, would see how close specific sound performance of the door, will arrive to the published requirements. A hi-end Home Cinemas Hertfordshire cinema design should take the information into consideration, to ensure a hi-end acoustical stop result.
