The reference level found in 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 instantly 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 room. Special room construction techniques allow us develop 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 lessen noise is given by its Sound transmission Class. This means, the higher in the 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 being a much larger hole. This acoustic property of sound could be a significant problem in a small cinema audio visual installation St Albans, where high quality construction is required. Which 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 grade of of the acoustical gasket in a house cinema installation, would determine how close the particular sound performance of the door, will come to the published standard. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical end result.
