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 hard 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 home installation, quite often we find bedrooms and other living areas to be right next to the Home Theater Installation Hertfordshire cinema room. Special room construction techniques allow us create 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 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 cut back 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 traverse any opening with very little claim. 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 have. 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 determine how close the actual sound performance of the door, will arrive to the published standard. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical conclude.
