The reference level of ones 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 instantly inside the cinema room. In non commercial installation, quite often we find bedrooms and other living areas to be right next towards the home cinema room. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors have been been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door determines its resistance towards the passage of any sound waves. A door’s ability to lessen noise is offered by its Sound transmission Class. This means, the higher inside Class the better the efficiency.
One more problem arises though; Sound waves can travel through any opening with very little impairment. And to top it off, a tiny hole in a barrier would transmit almost as much sound as being a much larger target. This acoustic property of sound could be an oversized problem in a home cinema audio visual installation St Albans, where high quality construction is required. In the area where acoustical gaskets come into appreciate. A home cinema door, so as 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 an at home cinema installation, would determine how close the actual sound performance of the door, will arrive 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.
