device for the experimental determination of the size of a sound environment and relevant process

摘要

the device is designed to perform has indirect measure of dimension of a sound environment and relevant process for it.the invention makes it possible to carry out this measure is in the "closed" environments such as concert halls, theaters, etc., and "open" for arenas, stadiums, squares, etc.it is composed of a speed meter (a) of acoustic energy from a meter of the decay time of the density of the sound energy (b)by measuring the sound absorption coefficient (c), locala circuit for the evaluation of the time delay of the acoustic system (d), and a circuit for evaluating the dimension acoustics environment, etc.the invention is in the technical field of the physics of sound, in particular that of control instruments of the acoustics.it can be applied wherever required surgery to measure the acoustic environment in open and closed.
