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 prospective inside the cinema room. In residential audio visual installation St Albans, 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 into the adjacent rooms.
However, doors continually been the weakest point, in this attempt. The mass, damping and stiffness of the home cinema door determines its resistance for the passage of any sound waves. A door’s ability to lessen noise is available from its Sound transmission Class. This means, the higher up the Class the better the efficiency.
One more problem arises though; Sound waves can traverse any opening with very little impairment. And to top it off, a tiny hole in a barrier would transmit nearly as much sound for a much larger hole. This acoustic property of sound could be an appreciable problem in a home cinema installation, where high quality construction is required. Which is where acoustical gaskets come into engage. 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 place cinema installation, would figure out how close specific sound performance of the door, arrives to the published standard. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical end result.
