The reference level of 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 instantly inside the cinema room. In a residential installation, quite often we find bedrooms and other living areas to be right next to the home cinema room. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission on the 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 towards the passage of any sound waves. A door’s ability to relieve 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 nearly as much sound like a much larger target. This acoustic property of sound could be an appreciable problem in your property cinema installation, where high quality construction is required. Which is where acoustical gaskets come into appreciate. A Home Cinema Installation Hertfordshire cinema door, to be able to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, the standard of of the acoustical gasket in a real estate cinema installation, would see how close specific sound performance of the door, will arrive to the published order. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical end result.
