METHOD FOR ACOUSTICALLY REPRESENTING SPATIAL INFORMATION TO BE USEABLE BY VISION INVALID PEOPLE

摘要

FIELD: medicine. SUBSTANCE: method involves using complex probing signal. Adjusted filtration response is close in this case to pulse- response characteristic of the scattering object. To bring the frequency and time signal ranges in correspondence with audio-analyzer, transformation is carried out in each channel to extend in time the adjusted filtration response. The set of signals being percepted by a vision invalid person, the state of the surrounding situation becomes observable acoustically. EFFECT: enhanced effectiveness in helping blind and invalid persons. 2 dwg, 1 tbl
