Home Cinema Installations and Sound Transmission Through Doors
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 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 to build a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors have been been the weakest point, in this attempt. The mass, damping and stiffness of the Home Cinema Installation St Albans cinema door determines its resistance towards passage of any sound waves. A door’s ability to lessen noise is written 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 nearly as much sound as a much larger target. This acoustic property of sound could be a big problem in a small cinema installation, where high quality construction is required. In the area where acoustical gaskets come into game. A home cinema door, so as to be effective, the seals around the head, jamb and sill must be complete and air-tight.
In other words, the standard of of the acoustical gasket in a home cinema installation, would see how close the particular sound performance of the door, arrives to the published standard. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical result.
