The reference level of one 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 household installation, quite often we find bedrooms and other living areas to be right next towards the home cinema room. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors have always 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 lessen 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 loss. And to top it off, a tiny hole in a barrier would transmit almost as much sound for a much larger hole. This acoustic property of sound could be a problem in a building cinema installation, where high quality construction is required. That’s the where acoustical gaskets come into engage. 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, exact same of the acoustical gasket in a real estate cinema installation, would see how close the particular sound performance of the door, will come to the published order. A hi-end Home Cinema Installation Hertfordshire cinema design should take every detail into consideration, to ensure a hi-end acoustical stop result.
