Home Cinema Installations and Firm Transmission Through Doors

The reference level found in a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not hard 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 a residential installation, quite often we find bedrooms and other living areas to be right next to the home cinema nursery. 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 generally been the weakest point, in such an 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 reduce noise is given by its Sound transmission Class. This means, the higher inside Class the better the efficiency.

One more problem arises though; Sound waves can travel through any opening with very little impairment. And to top it off, a tiny hole in a barrier would transmit almost as much sound like a much larger leak. This acoustic property of sound could be a problem in a small cinema audio visual installation St Albans, where high quality construction is required. Which is 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 grade of of the acoustical gasket in a home cinema installation, would determine how close a lot more sound performance of the door, will come to the published order. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical stop result.
