About

Younsik Park is a pioneering researcher in robotic auditory perception, with a primary focus on sound source localization and bio-inspired acoustic sensing. His foundational work, "Sound Source Localization using HRTF database" (2005, 24 citations), introduced a novel method leveraging Head-Related-Transfer-Functions for robot platforms, enabling precise spatial hearing without complex microphone arrays. This approach, which estimates sound direction from wave front time delays, has become a cornerstone for humanoid robotics and assistive technologies. Building on this, his 2007 study "Sound direction estimation using artificial ear" (12 citations) proposed an innovative artificial ear design that uses only two output signals to determine sound direction. By exploiting spectral features in head-related and interaural transfer functions across voice frequency bands, Park demonstrated that minimal hardware could achieve robust directional hearing. His work bridges the gap between human auditory physiology and machine hearing, offering elegant solutions for robots to interact naturally with sound environments. With a total of 36 citations across these key papers, Park’s contributions continue to influence research in auditory robotics, human-robot interaction, and assistive devices for the hearing impaired.
