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 prospective inside the cinema room. In a residential installation, quite often we find bedrooms and other living areas to be right next for the home cinema room. Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.

However, doors constantly been the weakest point, in type of attempt. The mass, damping and stiffness of the home cinema door will determine its resistance towards passage of any sound waves. A door’s ability to reduce noise is given by its Sound transmission Class. This means, the higher in the Class the better the efficiency.

One more problem arises though; Sound waves can traverse any opening with very little impairment. And to top it off, a tiny hole in a barrier would transmit almost as much sound for a much larger emergency. This acoustic property of sound could be an appreciable problem in a residential cinema installation, where high quality construction is required. That is where acoustical gaskets come into engage. 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, the quality of the acoustical gasket in a home cinema audio visual installation Hertfordshire, would see how close real sound performance of the door, will arrive to the published requirements. A hi-end home cinema design should take everything into consideration, to ensure a hi-end acoustical end result.
