Home Cinema Installations and Sound 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 the noise inside the cinema room. In non commercial installation, quite often we find bedrooms and other living areas to be right next to the Home Cinemas Hertfordshire cinema residence. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission to the adjacent rooms.

However, doors continually been the weakest point, in 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 lessen noise is given by its Sound transmission Class. This means, the higher up the Class the better the efficiency.

One more problem arises though; Sound waves can traverse any opening with very little harm. And to top it off, a tiny hole in a barrier would transmit nearly as much sound being a much larger hole. This acoustic property of sound could be a significant problem in a home cinema installation, where high quality construction is required. Which is 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 quality of the acoustical gasket in a home cinema installation, would see how close real sound performance of the door, stomach to the published specification. A hi-end home cinema design should take every detail into consideration, to ensure a hi-end acoustical conclude.
