Home Cinema Installations and Sound Transmission Through Doors
The reference level of 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 Cinemas Hertfordshire cinema room.
A problem occurs though, when we face the challenge of keeping prospective inside the cinema room. In residential installation, quite often we find bedrooms and other living areas to be right next to the home cinema room. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.
However, doors have always been the weakest point, in such an attempt. The mass, damping and stiffness of the home cinema door determines its resistance towards the passage of any sound waves. A door’s ability to lessen noise is offered by its Sound transmission Class. This means, the higher inside the Class the better the efficiency.
One more problem arises though; Sound waves can traverse any opening with very little impairment. And to top it off, a tiny hole in a barrier would transmit almost as much sound being a much larger target. This acoustic property of sound could be an oversized problem in a residential cinema installation, where high quality construction is required. Can be where acoustical gaskets come into play. 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 quality of the acoustical gasket in a house cinema installation, would figure out how close real sound performance of the door, stomach to the published requirements. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical end result.
