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 difficult to listen to, in a correctly designed Home Theater Installation St Albans 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 on the home cinema nursery. Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.
However, doors continually been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door will determine its resistance towards the passage of any sound waves. A door’s ability to reduce noise is available from its Sound transmission Class. This means, the higher in the Class the better the efficiency.
One more problem arises though; Sound waves can cross 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 emergency. This acoustic property of sound could be an appreciable problem in a small cinema installation, where high quality construction is required. That is where acoustical gaskets come into appreciate. A home cinema door, in order to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, the quality of the acoustical gasket in an at home cinema installation, would figure out how close real sound performance of the door, stomach to the published requirements. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical stem.
