Home Cinema Installations and Sounds Transmission Through Doors

The reference level of ones soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not hard 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 audio visual installation Hertfordshire, quite often we find bedrooms and other living areas to be right next for the home cinema nursery. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission on the adjacent rooms.

However, doors generally 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 reduce noise is given by its Sound transmission Class. This means, the higher inside 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 for a much larger hole. This acoustic property of sound could be an appreciable problem in a building cinema installation, where high quality construction is required. In the area 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 quality of the acoustical gasket in a house cinema installation, would figure out how close specific sound performance of the door, arrives to the published requirements. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical stem.
