The reference level of ones 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 a residential audio visual installation Hertfordshire, quite often we find bedrooms and other living areas to be right next for the home cinema home. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors generally been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door determines its resistance towards passage of any sound waves. A door’s ability to cut back 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 like a much larger emergency. This acoustic property of sound could be an oversized problem in a residential cinema installation, where high quality construction is required. Can be where acoustical gaskets come into engage. 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 actual of the acoustical gasket in an at home cinema installation, would see how close real sound performance of the door, arrives to the published specification. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical end result.
