People can learn to distinguish rotating objects by the way they echo sounds

image: Sensing system. (A) denotes the configuration of the sensing system for target geometry identification. Once the participants tap Android devices A and B, the synthetic echolocation signal is emitted from the loudspeaker (red lines). The emitted signal and its echoes from the target are recorded using the 1/7-scaled MDH (blue lines). The recorded binaural sounds, whose pitch is converted to 1/8 of the original by lowering the sampling frequency, are presented to the participants through headphones (green lines). (B) denotes the 1/7-scaled MDH with two microphones inserted in its ear canals for the binaural recordings. (C) denotes the Android devices A and B. view more
