Home Cinema Installations and Sounds Transmission Through Doors

The reference level about 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 the noise inside the cinema room. In home installation, quite often we find bedrooms and other living areas to be right next to your home cinema residence. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.

However, doors have always been the weakest point, in an attempt. The mass, damping and stiffness of the home cinema door will determine its resistance to the passage of any sound waves. A door’s ability to cut back noise is available from its Sound transmission Class. This means, the higher inside Class the better the efficiency.

One more problem arises though; Sound waves can cross 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 target. This acoustic property of sound could be a big problem in a small cinema installation, where high quality construction is required. Which is where acoustical gaskets come into appreciate. 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 standard of of the acoustical gasket in a home cinema audio visual installation St Albans, would figure out how close specific sound performance of the door, arrives to the published order. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical end result.
