The reference level found in a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not tough 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 audio visual installation Hertfordshire, quite often we find bedrooms and other living areas to be right next on the home cinema room. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors continually been the weakest point, in such an 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 cut back noise is available from its Sound transmission Class. This means, the higher within the Class the better the efficiency.
One more problem arises though; Sound waves can traverse any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit nearly as much sound like a much larger golf hole. 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 play. 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, the standard of of the acoustical gasket in a real estate cinema installation, would figure out how close real sound performance of the door, will arrive to the published requirements. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical end result.
