Echolocation by the blind – influence of signal type and directionality of the sound source on acoustic localization of obstacles

Echolocation by the blind – influence of signal type and directionality of the sound source on acoustic localization of obstacles


Introduction

Human echolocation is a confirmed and relatively well-documented phenomenon which allows blind persons to localize obstacles or perceive layouts of their surroundings using reflected sounds. Recently a number of studies have been devoted to analyzing the mechanism of echolocation and various factors affecting it, e.g. why some blind persons more easily become expert echolocators or how the mouth-clicks produced by experts differ from the average person.
