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 Installation St Albans cinema room.
A problem occurs though, when we face the challenge of keeping prospective inside the cinema room. In home installation, quite often we find bedrooms and other living areas to be right next to the home cinema residence. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.
However, doors continually been the weakest point, in this kind attempt. The mass, damping and stiffness of the home cinema door will determine its resistance towards the passage of any sound waves. A door’s ability to relieve noise is offered by its Sound transmission Class. This means, the higher within the Class the better the efficiency.
One more problem arises though; Sound waves can traverse any opening with very little claim. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as a much larger hole. This acoustic property of sound could be a problem in a residential cinema installation, where high quality construction is required. That is where acoustical gaskets come into engage. A home cinema door, to be able to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, the grade of of the acoustical gasket in an at home cinema installation, would see how close the actual sound performance of the door, will arrive to the published order. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical stop result.
