The reference level of 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 household 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 to build a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.
However, doors continually been the weakest point, in type of 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 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 traverse any opening with very little pain. And to top it off, a tiny hole in a barrier would transmit almost as much sound for a much larger target. This acoustic property of sound could be an appreciable problem in a small cinema installation, where high quality construction is required. That’s the 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 grade of of the acoustical gasket in an at home cinema audio visual installation Hertfordshire, would see how close real sound performance of the door, will arrive to the published specification. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical result.
