Past Event: AES SGS Research Colloquium #5: Listening Tests vs. Measurements

April 20, 2021 at 5:00 pm

Location: Zoom virtual Meeting (5pm Central European Time / Germany time zone)

Moderated by: Dr. Elena Shabalina

Speaker(s): Dr. Hyunkook Lee, Philipp Strobel

For this month’s AES South German Section Research Colloquium, two experts in the field of audio measurements and pychoacoustic perception will discuss their experiences regarding commonly used methods of listening tests, their evaluation and the analysis of measurements, with full interaction with the audience. Your questions are welcome!

The Experts

Dr. Hyunkook Lee
Dr. Hyunkook Lee
Dr. Hyunkook Lee is Associate Professor in Music Technology at the University of Huddersfield, UK. He heads the Applied Psychoacoustics Lab (APL) at Huddersfield, leading research in various areas of 3D audio (perception of height, recording, reproduction, virtual acoustics, 6DoF AR/VR audio, etc.). Before joining Huddersfield in 2010, he was a senior research engineer in audio R&D at LG Electronics, South Korea. He received a PhD degree in sound recording and psychoacoustic engineering and a bachelor's in music and sound recording (Tonmeister) from the University of Surrey in 2006 and 2002, respectively. He is a fellow of the AES, vice-chair of the AES high resolution audio technical committee and associate technical editor for Journal of the AES.

His talk will overview some of the classic psychometric listening test methods for detection/discrimination tasks and discuss how an ABX test could be conducted more rigorously following the threshold and signal detection theories, compared with conventional "self-switching" method. Potential influences of testing method on bias will also be discussed.

Philipp Strobel

After completing his master's degree in communications engineering, Philipp Strobel worked as a development engineer for RF hardware at Rohde&Schwarz GmbH & Co. KG. Since 2004, he applies his experience as a product manager at Rohde&Schwarz. He has been working in the field of digital signal processing for crosstalk cancellation, loudspeaker crossovers and room correction. Another focus of his work is binaural synthesis with headphones to simulate loudspeakers in space.

He will discuss how high-end headphones show very similar results in measurements but differ in their ability to reproduce details in recorded sound. What is missing here?

Join Meeting
The colloquium will be held in English with two presentations of 30 minutes each and a 30 minute discussion.
