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 non commercial installation, quite often we find bedrooms and other living areas to be right next to your home cinema nursery. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.

However, doors continually been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door determines its resistance to your passage of any sound waves. A door’s ability to lessen noise is written by its Sound transmission Class. This means, the higher inside the Class the better the efficiency.

One more problem arises though; Sound waves can traverse any opening with very little pain. And to top it off, a tiny hole in a barrier would transmit nearly as much sound being a much larger hole. This acoustic property of sound could be an appreciable problem in a residential cinema installation, where high quality construction is required. Can be where acoustical gaskets come into engage. A home cinema door, in order 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 house cinema installation, would figure out how close specific sound performance of the door, can come to the published standard. A hi-end Home Cinemas Hertfordshire cinema design should take every detail into consideration, to ensure a hi-end acoustical stem.
