It's important for the mother to be in the noise regime. At the same time, field studies of the sound field, in particular, measurements of the acoustic efficiency of noise protection measures and means, can be carried out only on an already existing object. It's practical for the can of arouse of the noise regime to be The task of analyzing and predicting noise mode on almost any object can be reduced to the construction of the model. Long before the authors' research, there were known requirements for similarity to modeling of wave emitted distribution processes: geometric similarity of the model of nature; observance of equality of relations of the linear sizes to wavelength in model and in kind; observance of equality of impedances in model and in kind. But it is necessary to supplement the system of known likeness requirements with analog and physical modeling. The system of strife, which is made by the authors, is to be put into such a system of vihelovny, I will expand, and I will transfer to the new yaks. The number of main constants of similarity is taken equal to 7, and other large-scale corroperative-pity are formulated according to the known in physics interdependences of physical values and represent a combination of such basic constants of similarity. The number of main constants of similarity is taken equal to 7, and other large-scale corroperative-pity are formulated according to the known in physics interdependences of physical values and represent a combination of such basic constants of similarity. Alternative (rather than joint) observance of some (and, accordingly, non-observance of other) forms of implementation (ie when all formulations are considered not in a complex, but as mutually incompatible alternatives) is a partial case of general regularity and is based on consciously idealized representation. About the isobaric flow of processes. Carrying out real-time simulation, observing the equality of adequate time intervals in the model and in kind, due to the fact that the model provides the speed of sound propagation, equal to the product of the speed of sound propagation in kind on the scale of linear dimensions.
Solved is very important for the practical purpose of the task of measuring the parameters of model radiation in dB with clear compliance with the requirements of similarity, which allows to tarize the scale of measuring devices properly.
