Robust Auditory Functions Based on Probabilistic Integration of MUSIC and CGMM
IEEE Access, 2021 Sound source localization and separation are essential functions for robot audition to comprehend acoustic environments. The widely-used multiple signal classification (MUSIC) can precisely estimate the directions of arrival (DoAs) of multiple sound ...

Acoustics, 2021 Wallach (J. Exp. Psychol. 1940, 27, 339–368) predicted that a human subject rotating about a vertical axis through the auditory centre, having an acoustic source rotating around the same axis at twice the rotation rate of the human subject, would ...

Motor data-regularized nonnegative matrix factorization for ego-noise suppression
EURASIP Journal on Audio, Speech, and Music Processing, 2020 Ego-noise, i.e., the noise a robot causes by its own motions, significantly corrupts the microphone signal and severely impairs the robot’s capability to interact seamlessly with its environment.

Acoustic SLAM Based on the Direction-of-Arrival and the Direct-to-Reverberant Energy Ratio
Drones, 2023 This paper proposes a new method that fuses acoustic measurements in the reverberation field and low-accuracy inertial measurement unit (IMU) motion reports for simultaneous localization and mapping (SLAM).

Object Surface Recognition Based on Standing Waves in Acoustic Signals
Frontiers in Robotics and AI, 2022 This paper proposes the use of the standing waves created by the interference between transmitted and reflected acoustic signals to recognize the size and the shape of a target object.

Robotics, 2016 Humans can recognize approximate room size using only binaural audition. However, sound reverberation is not negligible in most environments. The reverberation causes temporal fluctuations in the short-term interaural phase differences (IPDs) of sound ...
