The reference level found in a 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 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 on the home cinema environment. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.
However, doors generally been the weakest point, in this kind attempt. The mass, damping and stiffness of the home cinema door determines its resistance to the passage of any sound waves. A door’s ability to relieve 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 nearly as much sound for a much larger target. This acoustic property of sound could be a significant problem in a small cinema installation, where high quality construction is required. Can be where acoustical gaskets come into appreciate. A home cinema door, in order 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 real estate cinema installation, would see how close the particular sound performance of the door, can come to the published specification. A hi-end home cinema design should take every piece of information into consideration, to ensure a hi-end acoustical conclude.
