Home Cinema Installations and Firm 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 the noise inside the cinema room. In non commercial installation, quite often we find bedrooms and other living areas to be right next for the home cinema nursery. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission towards 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 lessen noise is given by its Sound transmission Class. This means, the higher within the 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 nearly as much sound as a much larger golf hole. This acoustic property of sound could be a big problem in a building cinema installation, where high quality construction is required. That is 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 audio visual installation St Albans, would see how close specific sound performance of the door, stomach to the published specification. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical stop result.
