Home Cinema Installations and Noise 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 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 towards the home cinema Home Cinema Installation Hertfordshire. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.

However, doors have been 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 lessen noise is available from its Sound transmission Class. This means, the higher in the Class the better the efficiency.

One more problem arises though; Sound waves can travel through any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as being a much larger hole. This acoustic property of sound could be a big problem in a home cinema installation, where high quality construction is required. In the area where acoustical gaskets come into appreciate. A home cinema door, in order 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 home cinema installation, would figure out how close real sound performance of the door, can come to the published standard. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical result.
