The reference level of a soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not hard 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 a residential installation, quite often we find bedrooms and other living areas to be right next on the home cinema nursery. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors continually been the weakest point, in an attempt. The mass, damping and stiffness of the home cinema door determines its resistance to the passage of any sound waves. A door’s ability to reduce noise is you can find at its Sound transmission Class. This means, the higher inside Class the better the efficiency.
One more problem arises though; Sound waves can travel through any opening with very little harm. And to top it off, a tiny hole in a barrier would transmit almost as much sound as being a much larger leak. This acoustic property of sound could be a significant 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, to be able to 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 audio visual installation St Albans, would figure out how close the actual sound performance of the door, can come to the published specification. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical stem.
