Home Cinema Installations and Noise Transmission Through Doors

The reference level about a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not challenging 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 non commercial installation, quite often we find bedrooms and other living areas to be right next to the home cinema residence. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.

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

One more problem arises though; Sound waves can traverse any opening with very little harm. And to top it off, a tiny hole in a barrier would transmit almost as much sound as being a much larger leak. This acoustic property of sound could be a significant problem in a small cinema installation, where high quality construction is required. Can be where acoustical gaskets come into have. 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, exact same of the acoustical gasket in a house cinema installation, would figure out how close specific sound performance of the door, will come to the published list of specifications. A hi-end Home Cinemas St Albans cinema design should take everything into consideration, to ensure a hi-end acoustical conclude.
