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 listen to, in a correctly designed Home Cinemas St Albans cinema room.
A problem occurs though, when we face the challenge of keeping the noise 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 nursery. Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors generally been the weakest point, in this kind attempt. The mass, damping and stiffness of the home cinema door will determine its resistance towards passage of any sound waves. A door’s ability to lessen noise is written by its Sound transmission Class. This means, the higher up the Class the better the efficiency.
One more problem arises though; Sound waves can traverse any opening with very little harm. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as a much larger target. This acoustic property of sound could be a significant problem in a building cinema installation, where high quality construction is required. That’s the where acoustical gaskets come into game. 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, the quality of the acoustical gasket in a place cinema installation, would figure out how close real sound performance of the door, will arrive to the published requirements. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical stop result.
