Abstract. A new construction device of modelling of acoustic processes on the territory of contemporary city is offered. Application of light not in visible one, and in an infra-red range takes enough large advantages in the plan of expansion range of possible scales of linear sizes at the modelling. Specification of component parts of device: variable model of the city territory; models of various sources of sound; mean of registration distributing of energy which is designed (eleсtronic-optical transformer). As sound and infrared radiation submit to conformities to the law of distribution identical for all types of waves, energy of infra-red radiations spreads on the surface of model identically. It is brought in a computer and the cards of noise, which describe distributing of acoustic contamination on territory of city, are built. The device of quazy-analogous modelling processes of distribution of sound, which will realize the set analogy between distribution of sound and electromagnetic waves, is created. Possibility of cartografing a map of the noise mode with the use of modern technologies by construction of cards of noise on results the quazyanalogous modelling is garanteed. Application of the offered solutions is especially actual in dwelling districts, adjoining to the industrial and transport objects, in particular, coal enterprises and motorways.
Keywords: acoustics; analogy; visualization of sound; card of noise; design.
