Home Cinema Installations and Sound Transmission Through Doors

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 instantly inside the cinema room. In home audio visual installation Hertfordshire, quite often we find bedrooms and other living areas to be right next towards the home cinema environment. Special room construction techniques allow us put together 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 for the passage of any sound waves. A door’s ability to cut back noise is offered by its Sound transmission Class. This means, the higher inside the Class the better the efficiency.

One more problem arises though; Sound waves can cross any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit almost as much sound being a much larger leak. This acoustic property of sound could be a big problem in a home cinema installation, where high quality construction is required. In the area where acoustical gaskets come into play. 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 quality of the acoustical gasket in a home cinema installation, would see how close real sound performance of the door, stomach to the published list of specifications. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical end result.
