The reference level of 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 installation, quite often we find bedrooms and other living areas to be right next to the home cinema environment. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors generally been the weakest point, in this kind attempt. The mass, damping and stiffness of the home cinema door will determine its resistance towards the passage of any sound waves. A door’s ability to lessen 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 cross any opening with very little pain. And to top it off, a tiny hole in a barrier would transmit almost as much sound like a much larger golf hole. This acoustic property of sound could be a significant problem in a small cinema installation, where high quality construction is required. Which is where acoustical gaskets come into engage. 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 real estate cinema audio visual installation Hertfordshire, would determine how close specific sound performance of the door, stomach to the published specification. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical stem.
