The reference level of a 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 typical inside the cinema room. In non commercial audio visual installation St Albans, quite often we find bedrooms and other living areas to be right next to the home cinema environment. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.
However, doors constantly been the weakest point, in type of attempt. The mass, damping and stiffness of the home cinema door determines its resistance to the passage of any sound waves. A door’s ability to lessen noise is available from its Sound transmission Class. This means, the higher inside the Class the better the efficiency.
One more problem arises though; Sound waves can cross any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit almost as much sound for a much larger hole. This acoustic property of sound could be a significant problem in a residential cinema installation, where high quality construction is required. In the area where acoustical gaskets come into appreciate. 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 particular sound performance of the door, stomach to the published order. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical end result.
