The reference level of a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not difficult to 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 a residential installation, quite often we find bedrooms and other living areas to be right next to your 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 have always been the weakest point, in such an attempt. The mass, damping and stiffness of the home cinema door determines its resistance to the passage of any sound waves. A door’s ability to relieve noise is you can find at 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 impairment. 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 appreciable problem in a small cinema installation, where high quality construction is required. Which 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 audio visual installation Hertfordshire, would determine how close a lot more sound performance of the door, can come to the published order. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical stop result.
