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 to listen to, in a correctly designed home cinema room.
A problem occurs though, when we face the challenge of keeping the noise inside the cinema room. In a residential 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 on the adjacent rooms.
However, doors continually been the weakest point, in type of 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 cut back noise is written 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 pain. And to top it off, a tiny hole in a barrier would transmit almost as much sound for a much larger leak. This acoustic property of sound could be a big problem in a residential cinema installation, where high quality construction is required. Can be where acoustical gaskets come into have. 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 standard of of the acoustical gasket in a home cinema audio visual installation Hertfordshire, would figure out how close a lot more sound performance of the door, will arrive to the published specification. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical result.
