The reference level about a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not challenging 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 on the home cinema room. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.
However, doors generally been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door will determine its resistance to your passage of any sound waves. A door’s ability lessen noise is available from its Sound transmission Class. This means, the higher inside 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 nearly as much sound being a much larger golf hole. This acoustic property of sound could be a problem in a small cinema installation, where high quality construction is required. In the area where acoustical gaskets come into play. A home cinema door, in an effort to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, the actual of the acoustical gasket in a home cinema installation, would determine how close the actual sound performance of the door, will arrive to the published standard. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical stop result.
