A well tried method which has been used over a long time frame for the acoustical design of a custom home cinema system is to create a smaller style of the cinema room, in mind which is like the original room, at the very least geometrically, and to study the propagation of waves in this model. This method has the advantage that, with little expenditure, a lot of variations can be used: from the choice of varied acoustic wall treatments to major changes in the form of the home cinema room.
Since several properties of propagation are normal to all types of waves, it is not absolutely necessary to use sound waves for the home cinema model measurements. More profitable is the use of light as a substitute of sound. The detection of the power distribution in the house cinema room can be carried out by photocells or by photography.
Although physical types of dedicated home cinemas are actually an extremely useful tool for the acoustical design, they’re being superseded gradually by a cheaper, faster and more efficient method, namely by digital simulation of sound propagation in enclosures. The introduction of the digital computer into room acoustics is probably due to M.R. Schroeder and his co-workers. Meanwhile, computer simulation has been applied not merely to home cinema systems, but to factories, auditorium and other working spaces as well.
Basically, there are two ways of sound field simulation used nowadays, for home cinema designs; namely ray tracing and the technique of image sources, and both derive from geometrical acoustics. Probably the most tedious and time consuming part of the whole process may be the collection and input of room data such as the positions and orientations of the house cinema’s walls and their acoustic properties. One can study the combined aftereffect of several source, and consider all home cinema speakers together. This permits home cinema designers to look for the optimal configuration of a speaker installation in a home cinema system.
There are イオンシネマ割引 based programs available today. They do not all guarantee exactly the same accuracy, so it is around the house cinema designer’s experience to choose which one computes better and reliable results. The computerised design of a house cinema room can be a big benefit; the software operator has the capacity to alter things and achieve a smooth and pleasant result for the home cinema’s seating area. It really is done prior to the home cinema installation and can achieve great acoustical end results.
