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 Cinemas Hertfordshire installation, quite often we find bedrooms and other living areas to be right next for the home cinema environment. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.
However, doors have been been the weakest point, in this kind 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 reduce noise is given 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 harm. And to top it off, a tiny hole in a barrier would transmit almost as much sound as a much larger golf hole. This acoustic property of sound could be an oversized problem in your property cinema installation, where high quality construction is required. That is where acoustical gaskets come into engage. A home cinema door, to be able to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, the actual of the acoustical gasket in a house cinema installation, would figure out how close real sound performance of the door, stomach to the published specification. A hi-end home cinema design should take every piece of information into consideration, to ensure a hi-end acoustical stop result.
