The reference level of a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not difficult 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 residential installation, quite often we find bedrooms and other living areas to be right next towards the home cinema environment. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors generally been the weakest point, in type of attempt. The mass, damping and stiffness of the home cinema door will determine its resistance to the passage of any sound waves. A door’s ability to reduce noise is you can find at 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 an oversized problem in a small cinema installation, where high quality construction is required. That is where acoustical gaskets come into have. 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 grade of of the acoustical gasket in a Home Cinemas Hertfordshire cinema installation, would see how close the particular sound performance of the door, arrives to the published list of specifications. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical conclude.
