Home Cinema Installations and Great 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 challenging to 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 towards the home cinema environment. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission on the 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 to the passage of any sound waves. A door’s ability to cut back noise is given 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 pain. And to top it off, a tiny hole in a barrier would transmit almost as much sound as being a much larger golf hole. This acoustic property of sound could be an appreciable problem in a home cinema audio visual installation Hertfordshire, where high quality construction is required. Which is where acoustical gaskets come into play. 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 quality of the acoustical gasket in a home cinema installation, would determine how close specific sound performance of the door, can come to the published list of specifications. A hi-end home cinema design should take the information into consideration, to ensure a hi-end acoustical stop result.
