Home Cinema Installations and Noise Transmission Through Doors

The reference level of ones 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 Theater Installation Hertfordshire cinema room.

A problem occurs though, when we face the challenge of keeping typical inside the cinema room. In non commercial installation, quite often we find bedrooms and other living areas to be right next on 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 generally been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door will determine its resistance to your passage of any sound waves. A door's ability to reduce noise is available from its Sound transmission Class. This means, the higher up 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 nearly as much sound as a much larger hole. This acoustic property of sound could be a significant problem in a building cinema installation, where high quality construction is required. That is where acoustical gaskets come into appreciate. A home cinema door, so as 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 see how close real sound performance of the door, will come to the published specification. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical end result.
