Home Cinema Installations and Sound 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 difficult to 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 residential installation, quite often we find bedrooms and other living areas to be right next for the home cinema room. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors have been been the weakest point, in such an attempt. The mass, damping and stiffness of the Home Cinemas St Albans cinema door determines its resistance towards the passage of any sound waves. A door’s ability to relieve noise is given by its Sound transmission Class. This means, the higher inside Class the better the efficiency.
One more problem arises though; Sound waves can traverse any opening with very little harm. And to top it off, a tiny hole in a barrier would transmit nearly as much sound like a much larger golf hole. This acoustic property of sound could be a big problem in a building cinema installation, where high quality construction is required. In the area where acoustical gaskets come into engage. 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, exact same of the acoustical gasket in a real estate cinema installation, would figure out how close the particular sound performance of the door, will arrive to the published requirements. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical end result.
