The reference level about a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not tough 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 towards the home cinema environment. Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission into 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 to the passage of any sound waves. A door’s ability to relieve noise is offered by its Sound transmission Class. This means, the higher inside the Class the better the efficiency.
One more problem arises though; Sound waves can travel through any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit nearly as much sound like a much larger golf hole. This acoustic property of sound could be an oversized problem in a residential cinema installation, where high quality construction is required. Which is where acoustical gaskets come into have. A Home Theater Installation St Albans 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 standard of of the acoustical gasket in a home cinema installation, would determine how close the actual sound performance of the door, arrives to the published standard. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical result.
