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 listen to, in a correctly designed Home Theater Installation St Albans cinema room.
A problem occurs though, when we face the challenge of keeping prospective inside the cinema room. In 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 to build a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors have always been the weakest point, in such an attempt. The mass, damping and stiffness of the home cinema door will determine its resistance for the passage of any sound waves. A door’s ability to cut back 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 cross any opening with very little impairment. And to top it off, a tiny hole in a barrier would transmit almost as much sound like a much larger target. This acoustic property of sound could be a problem in a residential cinema installation, where high quality construction is required. Which is where acoustical gaskets come into engage. A home cinema door, so that you can 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 a house cinema installation, would see how close the actual sound performance of the door, will come to the published specification. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical conclude.
