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 regular alarm inside the cinema room. In home installation, quite often we find bedrooms and other living areas to be right next on the home cinema residence. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.
However, doors constantly been the weakest point, in this kind 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 to lessen noise is written by its Sound transmission Class. This means, the higher up the Class the better the efficiency.
One more problem arises though; Sound waves can cross any opening with very little harm. And to top it off, a tiny hole in a barrier would transmit almost as much sound like a much larger golf hole. This acoustic property of sound could be a problem in a small cinema audio visual installation Hertfordshire, where high quality construction is required. That is 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 quality of the acoustical gasket in a real estate cinema installation, would see how close the particular 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.
