Home Cinema Installations and Noise 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 hard listen to, in a correctly designed home cinema room.

A problem occurs though, when we face the challenge of keeping prospective inside the cinema room. In home installation, quite often we find bedrooms and other living areas to be right next on the home cinema environment. Special room construction techniques allow us put together a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.

However, doors constantly been the weakest point, in such an 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 reduce noise is written by 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 like a much larger leak. This acoustic property of sound could be an appreciable problem in a residential cinema audio visual installation Hertfordshire, where high quality construction is required. Can be where acoustical gaskets come into game. A home cinema door, so as to be effective, the seals around the head, jamb and sill must be complete and air-tight.

In other words, exact same of the acoustical gasket in a real estate cinema installation, would see how close the particular sound performance of the door, stomach to the published order. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical stem.
