Distinguished Lecturer Seminar Series

Perceptual Audio Evaluation

Soren Bech
Bang & Olufsen, Denmark

Wednesday 30 January 2013
3.00pm
Bancroft Road Lecture Theatre BR 3.02

(preceded at 2.45pm by tea and followed by a reception
both in the Informatics Hub)

All welcome (especially students)
no pre-booking required

The talk will discuss all relevant aspects of perceptual evaluation of
audio signals. Topics will include 1) definition of a suitable research
question and associated hypothesis, 2) definition of the question to be
answered by the subject, 3) scaling of the subjective response, 4)
control of experimental variables such as choice of signal, reproduction
system, listening room, and selection of test subjects, 5) statistical
planning of the experiments, and 6) statistical analysis of the
subjective responses. The tutorial will include both theory and pratical
examples including discussion of the recommendations of relevant
international standards (IEC, ITU, ISO).

Biography: Soren Bech received a M.Sc. and a Ph.D. from the Department
of Acoustic Technology (AT) of the Technical University of Denmark. From
1982 - 92 he was a research Fellow at AT studying perception and
evaluation of reproduced sound in small rooms. In 1992 he joined Bang&
Olufsen as Technology Specialist and as of 2007 he is Head of Research.

Professor at McGill University, Faculty of Music and Visiting Professor
at the University of Surrey, Institute of Sound Recording and Adjunct
Professor at Aarhus University. Dr. Bech has been project manager of,
and active researcher in several international collaborative research
projects including "Archimedes" (perception of reproduced sound in small
rooms), ADTT (Advanced Digital Television Technologies), "Adonis" (Image
Quality of Television Displays), "LoDist" (perception of distortion in
loudspeakers units), "Medusa" (multichannel sound reproduction systems),
and "Vincent" (Flat panel display technologies). He was co-chair of ITU
task group 10/3 that authored the ITU BS.1116 standard. He was AES
Governor (1996-98) and AES Vice-President (2001-2006). He is currently
Associate Technical Editor of JAES and on the review board of JAES,
JASA, and Acta Acustica. He is a Fellow of AES and the Acoustical
Society of America and he has published numerous papers in JAES, JASA,
and other scientific journals. In 2006 his and Dr. Zacharov's book
"Perceptual Audio Evaluation - theory, method and application" was
published by Wiley.
