Home Cinema Installations and Firm Transmission Through Doors
The reference level of one 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 typical inside the cinema room. In residential installation, quite often we find bedrooms and other living areas to be right next to the home cinema room. Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission into the adjacent rooms.
However, doors generally been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door will determine its resistance towards the passage of any sound waves. A door’s ability to relieve noise is written by its Sound transmission Class. This means, the higher inside the Class the better the efficiency.
One more problem arises though; Sound waves can travel through any opening with very little claim. And to top it off, a tiny hole in a barrier would transmit almost as much sound being a much larger golf hole. This acoustic property of sound could be an appreciable problem in a Home Cinema Installation Hertfordshire cinema installation, where high quality construction is required. Can be where acoustical gaskets come into have. A home cinema door, so that you can 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 installation, would see how close real sound performance of the door, arrives to the published standard. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical result.
