Home Cinema Installations and Firm Transmission Through Doors
The reference level of one 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 instantly inside the cinema room. In non commercial installation, quite often we find bedrooms and other living areas to be right next to your home cinema home. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission into 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 to your passage of any sound waves. A door’s ability to lessen noise is offered 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 claim. And to top it off, a tiny hole in a barrier would transmit almost as much sound like a much larger target. This acoustic property of sound could be an oversized problem in a home cinema installation, where high quality construction is required. That is where acoustical gaskets come into have. A home cinema door, in order to 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 home cinema installation, would see how close real sound performance of the door, can come to the published standard. A hi-end Home Cinemas St Albans cinema design should take every detail into consideration, to ensure a hi-end acoustical stop result.
