Home Cinema Installations and Sound 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 difficult to 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 non commercial audio visual installation Hertfordshire, quite often we find bedrooms and other living areas to be right next towards the home cinema room. 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 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 lessen 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 cross any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as a much larger emergency. This acoustic property of sound could be a problem in a small cinema installation, where high quality construction is required. That’s the where acoustical gaskets come into play. 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 actual of the acoustical gasket in an at home cinema installation, would determine how close real sound performance of the door, can come to the published specification. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical result.
