Unlike vision, the mechanisms underlying auditory motion perception are
poorly understood. Here we describe an auditory motion illusion revealing
a novel cue to auditory speed perception: the temporal frequency of
amplitude modulation (AM-frequency), typical for rattling sounds.
Naturally, corrugated objects sliding across each other generate rattling
sounds whose AM-frequency tends to directly correlate with speed. We found
that AM-frequency modulates auditory speed perception in a highly
systematic fashion: moving sounds with higher AM-frequency are perceived
as moving faster than sounds with lower AM-frequency. Even more
interestingly, sounds with higher AM-frequency also induce stronger motion
aftereffects. This reveals the existence of specialized neural mechanisms
for auditory motion perception, which are sensitive to AM-frequency. Thus,
in spatial hearing, the brain successfully capitalizes on the AM-frequency
of rattling sounds to estimate the speed of moving objects. This tightly
parallels previous findings in motion vision, where spatio-temporal
frequency of moving displays systematically affects both speed perception
and the magnitude of the motion aftereffects. Such an analogy with vision
suggests that motion detection may rely on canonical computations, with
similar neural mechanisms shared across the different modalities.
