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 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 household installation, quite often we find bedrooms and other living areas to be right next for the home cinema environment. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.
However, doors constantly been the weakest point, in an 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 lessen noise is offered by its Sound transmission Class. This means, the higher up the Class the better the efficiency.
One more problem arises though; Sound waves can travel through any opening with very little impairment. And to top it off, a tiny hole in a barrier would transmit nearly as much sound for a much larger hole. This acoustic property of sound could be an oversized problem in a residential cinema installation, where high quality construction is required. That’s the where acoustical gaskets come into game. 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, exact same of the acoustical gasket in an at home cinema installation, would see how close the actual sound performance of the door, stomach to the published specification. A hi-end Home Cinema Installation St Albans cinema design should take all the info into consideration, to ensure a hi-end acoustical conclude.
