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 tough listen to, in a correctly designed home cinema room.

A problem occurs though, when we face the challenge of keeping instantly inside the cinema room. In household installation, quite often we find bedrooms and other living areas to be right next for the home cinema residence. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.

However, doors have always been the weakest point, in this 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 lessen noise is written 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 impairment. And to top it off, a tiny hole in a barrier would transmit almost as much sound for a much larger target. This acoustic property of sound could be an oversized problem in a small cinema installation, where high quality construction is required. Which is where acoustical gaskets come into play. 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, exact same of the acoustical gasket in a house cinema audio visual installation St Albans, would see how close the actual sound performance of the door, arrives to the published specification. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical end result.
