Home Cinema Installations and Noise 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 tough listen to, in a correctly designed home cinema room.

A problem occurs though, when we face the challenge of keeping the noise inside the cinema room. In residential audio visual installation Hertfordshire, quite often we find bedrooms and other living areas to be right next to your 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 have been been the weakest point, in such an attempt. The mass, damping and stiffness of the home cinema door determines its resistance to the passage of any sound waves. A door’s ability to reduce noise is given by its Sound transmission Class. This means, the higher in the Class the better the efficiency.

One more problem arises though; Sound waves can cross any opening with very little harm. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as being a much larger golf hole. This acoustic property of sound could be an appreciable problem in your property 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, exact same of the acoustical gasket in a house cinema installation, would see how close the actual sound performance of the door, can come to the published requirements. A hi-end home cinema design should take every piece of information into consideration, to ensure a hi-end acoustical stop result.
