Home Cinema Installations and Sound Transmission Through Doors

The reference level found in a 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 residential audio visual installation St Albans, 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 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 towards 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 up the Class the better the efficiency.

One more problem arises though; Sound waves can traverse any opening with very little claim. And to top it off, a tiny hole in a barrier would transmit almost as much sound as being a much larger leak. This acoustic property of sound could be a problem in a building cinema installation, where high quality construction is required. That’s the where acoustical gaskets come into engage. 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 house cinema installation, would determine how close real sound performance of the door, will arrive to the published standard. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical stem.
