The reference level of ones 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 the noise inside the cinema room. In residential installation, quite often we find bedrooms and other living areas to be right next on the home cinema environment. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors continually been the weakest point, in this kind attempt. The mass, damping and stiffness of the home cinema door determines its resistance for the passage of any sound waves. A door’s ability to cut back noise is offered by its Sound transmission Class. This means, the higher inside the Class the better the efficiency.
One more problem arises though; Sound waves can traverse any opening with very little claim. And to top it off, a tiny hole in a barrier would transmit almost as much sound being a much larger golf hole. This acoustic property of sound could be an oversized problem in a building cinema installation, where high quality construction is required. That is where acoustical gaskets come into game. 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 house cinema audio visual installation Hertfordshire, would determine how close specific sound performance of the door, will arrive to the published specification. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical stem.
