Abstract

Some blind individuals have the ability to detect and classify objects in
complex scenes by using echolocation based on "tongue clicks". In this
paper, we present a waveform analysis of the tongue clicks collected
from three blind individuals who use tongue-click based echolocation on
a daily basis. It is found that the tongue clicks are wideband signals and
that that the spectrum of clicks varies within and between individuals.
However, by using the wideband ambiguity function, we find that
all of the clicks from three different individuals share some common
characteristics.
