Home Cinema Installations and Great 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 hard 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 a 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 create a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.
However, doors have always been the weakest point, in this kind attempt. The mass, damping and stiffness of the home cinema door determines its resistance towards the passage of any sound waves. A door’s ability to cut back noise is offered by its Sound transmission Class. This means, the higher in the Class the better the efficiency.
One more problem arises though; Sound waves can cross any opening with very little pain. And to top it off, a tiny hole in a barrier would transmit nearly as much sound for a much larger leak. This acoustic property of sound could be a significant problem in a home cinema installation, where high quality construction is required. Can be where acoustical gaskets come into have. A home cinema door, to be able 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 real estate cinema audio visual installation Hertfordshire, would determine how close the particular sound performance of the door, can come to the published order. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical end result.
