Research Interests
My PhD research is focused on indoor acoustic channel characterization using acoustical image method, and use the indoor channel information in estimating a source location. In a recent publication on “Distributed Sensing for Acoustic Source Localization in Indoor Reverberant Environments” that I co-authored, where Jetz’s and triangulation methods were utilized in estimating a source location using room impulse response received at distributed acoustic sensors.
