METHOD AND ACOUSTIC SYSTEM FOR SONIFICATION OF ENCLOSED AND OPEN SPACES

摘要

A method and an acoustic system for sonification of enclosed and open spaces are used for sonification of enclosed and open spaces with the use of acoustic pseudosystems. In a method for sonification of enclosed and open spaces which includes separation of spectral components of the electric signal corresponding to different frequency bands, conversion of the electric signals into acoustic ones by means of pairwise and in-phase connected main and additional electroacoustic radiation heads providing for coherency of the acoustic waves and mounted in parallel and axially-opposite manner so that their front panels face each other at different distances corresponding to their different frequency bands, the main and the additional heads are mounted at the distances from each other correspondingly equal to 0.5-2.0 of the distances at which the irregularity of the frequency response is minimal within each frequency band in the directions which are perpendicular to the axes along which are mounted the radiation heads and which are not limited by their front panels, the characteristic sensibility of each additional radiator being so chosen that it exceeds by 1-12 dB that of each main radiator and the excess sound power fed to the heads of the additional radiations being dampened during the whole sonification process. Besides, the main and additional radiation heads with different frequency bands facing each other by their front panels are mounted in one or different planes in relation to each other. <MATH>
