Auditory lateralization steering independent of loudspeaker position using sound from ultrasound

There are a lot of impaired vision people and they are planning physical access by information of positional relationships of auditory cues or by oneself. In this paper, we propose auditory lateralization guide independent of loudspeaker position by using super-directional speaker system for pinpoint presentation and suppressing spread sounds because the individual who do not offer the support would feel it as noise. Through the experiments, it was confirmed that we could steer the auditory lateralization that the supported individual would percept, by using the acoustic signal which was convoluted with the impulse response recorded on dummy head corresponds to the direction which want to present.
