The reference level of 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 prospective 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 residence. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.

However, doors have been been the weakest point, in an attempt. The mass, damping and stiffness of the home cinema door will determine its resistance towards passage of any sound waves. A door’s ability to cut back noise is given by its Sound transmission Class. This means, the higher in the Class the better the efficiency.

One more problem arises though; Sound waves can traverse any opening with very little claim. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as a much larger golf hole. This acoustic property of sound could be a problem in a home cinema installation, where high quality construction is required. Which is where acoustical gaskets come into play. A home cinema door, in an effort to be effective, the seals around the head, jamb and sill must be complete and air-tight.

In other words, the quality of the acoustical gasket in a real estate cinema audio visual installation St Albans, would determine how close the particular sound performance of the door, can come to the published order. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical result.
