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 hard 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 for the home cinema home. Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors have been been the weakest point, in type of attempt. The mass, damping and stiffness of the home cinema door determines its resistance towards passage of any sound waves. A door’s ability to reduce noise is you can find at its Sound transmission Class. This means, the higher in 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 like a much larger emergency. This acoustic property of sound could be a problem in a small cinema installation, where high quality construction is required. Can be 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 grade of of the acoustical gasket in a house cinema audio visual installation St Albans, would figure out how close real sound performance of the door, will come to the published requirements. A hi-end home cinema design should take every piece of information into consideration, to ensure a hi-end acoustical result.
