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 hard 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 household installation, quite often we find bedrooms and other living areas to be right next towards the home cinema home. Special room construction techniques allow us to build a sufficient noise barrier, in order to reduce any sound transmission on the adjacent rooms.
However, doors have always been the weakest point, in type of attempt. The mass, damping and stiffness of the home cinema door will determine its resistance to your passage of any sound waves. A door’s ability to lessen 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 traverse any opening with very little claim. And to top it off, a tiny hole in a barrier would transmit almost as much sound like a much larger leak. This acoustic property of sound could be an oversized problem in a residential cinema audio visual installation St Albans, where high quality construction is required. That is where acoustical gaskets come into game. A home cinema door, to be able 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 real estate cinema installation, would see how close the actual sound performance of the door, will arrive to the published standard. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical end result.
