The reference level about 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 on the home cinema environment. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.
However, doors generally been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door will determine its resistance to the passage of any sound waves. A door’s ability to cut back 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 travel through any opening with very little pain. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as being a much larger hole. This acoustic property of sound could be a significant problem in a residential cinema audio visual installation Hertfordshire, where high quality construction is required. Can be where acoustical gaskets come into game. A home cinema door, so as 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 place cinema installation, would determine how close real sound performance of the door, stomach to the published standard. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical stem.
