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 regular alarm inside the cinema room. In Home Theater Installation St Albans installation, quite often we find bedrooms and other living areas to be right next towards the home cinema room. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors have always been the weakest point, in this kind attempt. The mass, damping and stiffness of the home cinema door determines its resistance for the passage of any sound waves. A door’s ability to lessen noise is offered by its Sound transmission Class. This means, the higher in the Class the better the efficiency.
One more problem arises though; Sound waves can traverse 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 golf hole. This acoustic property of sound could be a problem in a small cinema installation, where high quality construction is required. That’s the where acoustical gaskets come into have. 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 house cinema installation, would determine how close the actual sound performance of the door, can come to the published specification. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical end result.
