Abstract

Purpose. A quantitative and highquality estimation of distribution of noise is in difficult terms, taking into account the great number of cofactors and wave phenomena, - (interference, diffraction and other) - can be got by the construction of models which are based on the analogy of acoustic and optical processes. A research method consists in a study not in itself the probed phenomenon, but in scientific research of some similar phenomenon or process of other physical nature, which are described correlations, in relation to the got results. The new construction of device of design is offered. Methodology. The new construction of device of design is offered. Application of light not in a visible, but in infrared range has large enough advantages in the plan of expansion of range of possible scales of linear sizes at a design. Specification of component parts of device: it is a variable model of city territory; are models of various sources of sound; mean of registration of distributing of energy which is designed (myriatron). Device of visualization and with the undiscrete method of registration of distributing of energy which is designed, on the surface of model of ob''ekta works by such method. With the observance of requirements of geometrical similarity collect the model of city building, setting on the basis of model of city houses and buildings, facilities of fight, with noise, models of point and linear sources of sound. Intensity of infrared on a model is picked up the proportion of intensity of sound in nature, using the prepared correlations adjustings of strength of current of electric feed of models of sources of noise. The frequency spectrum of infrared - of radiation in a model is picked up proportional the frequency spectrum of sound in nature in accordance with the above-described requirements of podibnosti. As a sound and infrared radiation submits identical for all types of waves conformities to law of distribution, energy of infrared - of radiation spreads on the surface of model identically that is why, as energy of sound spreads on the surface of model object (with an observance all features of the diffraction and interference phenomena). Findings. A town-planning situation with the areas of acoustic shade from three buildings was designed by us repeatedly (with various variations). Present complete equivalence of stand-ard map of noise and map of noise, which is got in the process of design. Originality. A design method is invented in an acoustician which applies the set analogy between distribution of sound and hertzian waves, and the device of design which uses such method is created. Practical value. Due to author inventions possibility of mapping of the noise mode is welltodo with the use of modern technologies, by the construction of maps of noise on results a quazianalogy design.
