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

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

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

One more problem arises though; Sound waves can traverse any opening with very little claim. And to top it off, a tiny hole in a barrier would transmit almost as much sound as a much larger golf hole. This acoustic property of sound could be a significant problem in a small cinema installation, where high quality construction is required. Which is where acoustical gaskets come into appreciate. 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 grade of of the acoustical gasket in a house cinema installation, would see how close real sound performance of the door, arrives to the published requirements. A hi-end home cinema design should take every piece of information into consideration, to ensure a hi-end acoustical result.
