Abstract

Способ акустического представления пространственной информации для пользователей, заключающийся в излучении ультразвукового частотно-модулированного импульса, бинауральном приеме эхосигнала на два ультразвуковых микрофона, усилении, преобразовании электрических сигналов в акустические, согласованной фильтрации эхосигналов, временном растяжении полученных откликов в каналах бинаурального приема, последующим восприятием сигналов слуховым анализатором человека, отличающийсятем, что дополнительно проводят статистический анализ восприятия акустических сигналов слуховым анализатором пользователя для получения корректирующих коэффициентов усиления для каждого канала и после операции согласованной фильтрации производят многоканальную масштабно-временную фильтрацию откликов путем их прямого и обратного вейвлет-преобразования с последующим весовым суммированием выходных сигналов каждого канала с учетом полученных корректирующих коэффициентов усиления в каждом канале.The method of acoustic representation of spatial information for users, which consists in emitting an ultrasonic frequency-modulated pulse, binaural receiving an echo signal into two ultrasonic microphones, amplifying, converting electrical signals into acoustic ones, coordinated filtering of echo signals, temporarily stretching the received responses in binaural reception channels, followed by auditory signal perception human analyzer, characterized in that additionally conduct statistical analysis perception of acoustic signals by the user’s auditory analyzer to obtain corrective gain factors for each channel, and after the matched filtering operation, perform multi-channel time-scale filtering of responses by direct and inverse wavelet transform with subsequent weighted summation of the output signals of each channel taking into account the received correction factors in each channel.
