The reference level of one soundtrack is 105db and 115db for the LFE channel. Most people would find these levels quite high, but not tough 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 a residential installation, quite often we find bedrooms and other living areas to be right next towards the home cinema residence. Special room construction techniques allow us create a sufficient noise barrier, in order to reduce any sound transmission towards the adjacent rooms.
However, doors generally been the weakest point, in this kind attempt. The mass, damping and stiffness of the home cinema door determines its resistance to your passage of any sound waves. A door's ability to relieve noise is written by its Sound transmission Class. This means, the higher inside the Class the better the efficiency.
One more problem arises though; Sound waves can cross any opening with very little pain. 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 an oversized problem in a building cinema installation, where high quality construction is required. That is where acoustical gaskets come into engage. 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 real estate cinema audio visual installation Hertfordshire, would determine how close the particular sound performance of the door, will arrive to the published order. A hi-end home cinema design should take all the info into consideration, to ensure a hi-end acoustical stem.
