The reference level of ones 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 regular alarm inside the cinema room. In household installation, quite often we find bedrooms and other living areas to be right next on the home cinema environment. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission on the adjacent rooms.
However, doors continually been the weakest point, in 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 relieve noise is given by its Sound transmission Class. This means, the higher up the 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 almost as much sound like a much larger emergency. This acoustic property of sound could be a problem in a home cinema installation, where high quality construction is required. In the area where acoustical gaskets come into have. A home cinema door, in an effort 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 house cinema audio visual installation St Albans, would figure out how close specific sound performance of the door, will arrive to the published specification. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical result.
