The reference level of one soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not challenging to 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 a residential audio visual installation St Albans, quite often we find bedrooms and other living areas to be right next to the home cinema residence. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.
However, doors have always 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 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 nearly as much sound for a much larger emergency. This acoustic property of sound could be an oversized problem in your property cinema installation, where high quality construction is required. Which is where acoustical gaskets come into have. 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 standard of of the acoustical gasket in a home cinema installation, would determine how close real sound performance of the door, can come to the published specification. A hi-end home cinema design should take every piece of information into consideration, to ensure a hi-end acoustical stem.
