The reference level about a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not difficult 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 non commercial installation, quite often we find bedrooms and other living areas to be right next towards the home cinema residence. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission on 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 to the passage of any sound waves. A door’s ability to reduce 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 traverse any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit almost as much sound like a much larger target. This acoustic property of sound could be an appreciable problem in a residential cinema installation, where high quality construction is required. That’s the where acoustical gaskets come into game. 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 grade of of the acoustical gasket in a real estate cinema installation, would see how close specific sound performance of the door, will arrive to the published order. A hi-end Home Cinemas Hertfordshire cinema design should take the information into consideration, to ensure a hi-end acoustical result.
