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 household installation, quite often we find bedrooms and other living areas to be right next to the home cinema residence. Special room construction techniques allow us produce a sufficient noise barrier, in order to reduce any sound transmission towards adjacent rooms.

However, doors generally been the weakest point, in such 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 reduce noise is available from its Sound transmission Class. This means, the higher up the Class the better the efficiency.

One more problem arises though; Sound waves can travel through any opening with very little loss. And to top it off, a tiny hole in a barrier would transmit nearly as much sound for 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. Can be where acoustical gaskets come into have. A home cinema door, in order 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 St Albans, would see 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 result.
