Home Cinema Installations and Sound 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 regular alarm inside the cinema room. In non commercial installation, quite often we find bedrooms and other living areas to be right next to your Home Theater Installation St Albans cinema room. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.

However, doors continually been the weakest point, in this kind attempt. The mass, damping and stiffness of the home cinema door determines its resistance towards passage of any sound waves. A door’s ability to reduce noise is offered by its Sound transmission Class. This means, the higher inside the Class the better the efficiency.

One more problem arises though; Sound waves can travel through any opening with very little harm. And to top it off, a tiny hole in a barrier would transmit almost as much sound like a much larger golf hole. This acoustic property of sound could be a big problem in a small cinema installation, where high quality construction is required. That’s the where acoustical gaskets come into game. A home cinema door, in an effort 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 real estate cinema installation, would determine how close specific sound performance of the door, can come to the published requirements. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical end result.
