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 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 installation, quite often we find bedrooms and other living areas to be right next for the home cinema home. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors have been been the weakest point, in this 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 relieve noise is written by its Sound transmission Class. This means, the higher inside the Class the better the efficiency.
One more problem arises though; Sound waves can cross any opening with very little pain. And to top it off, a tiny hole in a barrier would transmit almost as much sound like a much larger emergency. This acoustic property of sound could be a big problem in a Home Cinema Installation Hertfordshire cinema installation, where high quality construction is required. Can be where acoustical gaskets come into play. 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 standard of of the acoustical gasket in a home cinema installation, would determine how close real sound performance of the door, arrives to the published standard. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical stop result.
