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 hard 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 to the home cinema room. Special room construction techniques allow us develop a sufficient noise barrier, in order to reduce any sound transmission on the adjacent rooms.
However, doors continually been the weakest point, in this 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 lessen 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 travel through any opening with very little claim. And to top it off, a tiny hole in a barrier would transmit nearly as much sound as a much larger emergency. This acoustic property of sound could be a big problem in your property cinema installation, where high quality construction is required. Can be where acoustical gaskets come into play. A home cinema door, so that you can 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 place cinema audio visual installation Hertfordshire, would figure out how close real sound performance of the door, arrives to the published order. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical result.
