The reference level of ones 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 Cinemas Hertfordshire cinema room.
A problem occurs though, when we face the challenge of keeping instantly inside the cinema room. In home installation, quite often we find bedrooms and other living areas to be right next for the home cinema residence. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors continually been the weakest point, in type of 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 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 being a much larger hole. This acoustic property of sound could be an oversized problem in a small cinema installation, where high quality construction is required. Which is where acoustical gaskets come into game. 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 grade of of the acoustical gasket in a place cinema installation, would see how close specific sound performance of the door, arrives to the published standard. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical stem.
