Home Cinema Acoustic Model Design
A well tried method which has been used over a long period of time for the acoustical design of a bespoke home cinema system is to build a smaller model of the cinema room, under consideration which is similar to the original room, at least geometrically, and to study the propagation of waves in this model. This method has the advantage that, with little expenditure, a great number of variations can be tried out: from the choice of various acoustic wall treatments to major changes in the shape of the home cinema room. Since several properties of propagation are common to all sorts 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 energy distribution in the home cinema room can be carried out by photocells or by photography. Although physical models of dedicated home cinemas have proven to be a very useful tool for the acoustical design, they are bein...
