Home Cinema Installations and Sound Transmission Through Doors
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 difficult 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 residential installation, quite often we find bedrooms and other living areas to be right next to the home cinema residence. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors constantly been the weakest point, in an attempt. The mass, damping and stiffness of the Home Theater Installation Hertfordshire cinema door will determine its resistance towards the passage of any sound waves. A door’s ability lessen noise is offered by 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 loss. And to top it off, a tiny hole in a barrier would transmit nearly as much sound like a much larger hole. This acoustic property of sound could be a significant problem in a small cinema installation, 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 specification. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical stop result.
