The reference level about 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 the noise inside the cinema room. In a residential audio visual installation Hertfordshire, quite often we find bedrooms and other living areas to be right next to your home cinema home. Special room construction techniques allow us to build 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 will determine its resistance towards the passage of any sound waves. A door’s ability lessen noise is given by its Sound transmission Class. This means, the higher up the Class the better the efficiency.
One more problem arises though; Sound waves can travel through any opening with very little pain. And to top it off, a tiny hole in a barrier would transmit almost as much sound as being a much larger emergency. This acoustic property of sound could be a big problem in a residential cinema installation, where high quality construction is required. In the area where acoustical gaskets come into game. A home cinema door, so that you can be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, the quality of the acoustical gasket in an at home cinema installation, would determine how close real sound performance of the door, arrives to the published requirements. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical stop result.
