The reference level about a 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 home installation, quite often we find bedrooms and other living areas to be right next for the home cinema residence. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors have always been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door determines its resistance for the passage of any sound waves. A door's ability to relieve noise is available from its Sound transmission Class. This means, the higher up 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 golf hole. This acoustic property of sound could be an oversized problem in a building 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, exact same of the acoustical gasket in a home cinema audio visual installation St Albans, would figure out how close a lot more sound performance of the door, will come to the published specification. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical conclude.
