Home Cinema Installations and Sounds 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 regular alarm inside the cinema room. In a residential installation, quite often we find bedrooms and other living areas to be right next to your Home Theater Installation Hertfordshire cinema environment. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.

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

One more problem arises though; Sound waves can travel through any opening with very little harm. And to top it off, a tiny hole in a barrier would transmit nearly as much sound for 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. That’s the where acoustical gaskets come into game. A home cinema door, so that you can be effective, the seals around the head, jamb and sill must be complete and air-tight.

In other words, the standard of of the acoustical gasket in an at home cinema installation, would determine how close the actual sound performance of the door, will arrive to the published list of specifications. A hi-end home cinema design should take every piece of information into consideration, to ensure a hi-end acoustical stop result.
