I am Taewoong Lee, a Ph.D. student under the supervision of Prof. Mads Græsbøll Christensen and Assoc. Prof. Jesper Kjær Nielsen at Aalborg University. I was awarded the North Jutland University Foundation’s Innovation Prize in 2019, and I published one journal paper and four conference papers in relate to my Ph.D. work from 2017 to 2020. We are pursuing creation of multiple sound zones (listening areas) for different audio contents in the same space without head- or ear-phones.
