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 prospective inside the cinema room. In non commercial installation, quite often we find bedrooms and other living areas to be right next to the home cinema environment. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission to 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 for the passage of any sound waves. A door’s ability to lessen noise is written 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 as being a much larger hole. This acoustic property of sound could be an oversized problem in a home cinema installation, where high quality construction is required. That’s the 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 house cinema audio visual installation St Albans, would figure out how close the actual sound performance of the door, stomach to the published order. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical end result.
