The reference level of a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not tough 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 non commercial installation, quite often we find bedrooms and other living areas to be right next for the home cinema nursery. 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 continually been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door determines its resistance to your passage of any sound waves. A door’s ability to lessen noise is you can find at its Sound transmission Class. This means, the higher inside the Class the better the efficiency.
One more problem arises though; Sound waves can cross any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit almost as much sound being a much larger hole. This acoustic property of sound could be an oversized problem in a residential cinema installation, where high quality construction is required. That is where acoustical gaskets come into have. A home cinema door, to be able 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 Cinemas St Albans cinema installation, would determine how close the particular sound performance of the door, will arrive to the published requirements. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical stop result.
