Home Cinema Installations and Sounds Transmission Through Doors
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 Cinemas Hertfordshire cinema room.
A problem occurs though, when we face the challenge of keeping instantly inside the cinema room. In a residential installation, quite often we find bedrooms and other living areas to be right next for the home cinema nursery. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission on the adjacent rooms.
However, doors continually been the weakest point, in type of attempt. The mass, damping and stiffness of the home cinema door will determine its resistance to your passage of any sound waves. A door’s ability to cut back noise is given 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 nearly as much sound being a much larger hole. This acoustic property of sound could be a problem in a residential cinema installation, where high quality construction is required. In the area 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 figure out how close specific sound performance of the door, can come to the published standard. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical stop result.
