Special session


In 2018, two world-renowned Professors, outstanding specialists in the field of acoustics and psychoacoustics departed from us: Professor Józef Zwisłocki and Professor Andrzej Rakowski. They made a significant contribution to the development of knowledge about the mechanisms of hearing, inspiring scientists in many scientific centers all around the world. Inviting you to take part in this session, we would like to draw your attention to the exchange of scientific experiences between people dealing with current research problems in the areas of psychoacoustics. At the same time, we would like to identify the most important scientific problems that are awaiting to be solved and which are worth the attention of a wider research group.

This session will be an expression of remembrance of the achievements of the two outstanding Professors. Over the years theirs scientific successes have become the driving force for further generations of acoustician for further intensive development of the study of auditory system and sound perception processes.

It is worth mentioning the most important scientific achievements of the Professors. Professor Józef Zwisłocki is the author of over 200 scientific publications, many books as well as numerous patents in the field of acoustics. He has developed the model of an artificial ear which is an essential element of the so-called "Zwisłocki's coupler". Professor Zwisłocki was a member of many prestigious and global acoustic and audiological scientific societies. In 1991 he was awarded the honorary doctorate of the University of Adam Mickiewicz in Poznan.

Professor Andrzej Rakowski connected his scientific activity with Fryderyk Chopin University of Music in Warsaw. He also published over 200 scientific articles, presented many lectures at prestigious international conferences as an invited speaker and completed his academic trainings at well-established universities in the USA, Kanda, Great Britain and Germany.

The scientific interests of both Professors were largely convergent, as they were concerned with the perception of loudness and pitch and the peripheral part of the auditory system functioning. Professor Zwisłocki conducted research on the functioning of the middle ear and the cochlea. In particular, he has proposed and developed diagnostic methods of hearing examinations. In turn, Prof. Rakowski specialized in research on mechanisms responsible for creating the impression/sensation of pitch, timbre and sound roughness. He was also deeply involved in a research connected with the phenomenon of absolute pitch.

Nowadays, psychoacoustics has branched out to many areas of acoustics, especially hearing sciences. Organizing the session commemorating the two Professors we want to show and emphasize the role and significance of psychoacoustics. This branch of hearing science is concerned mainly with areas such as: modeling of the auditory system, speech intelligibility, musical acoustics, hearing aids, soundscape, room acoustics and objective methods of the hearing diagnostic. . We expect that the participants of this session will ultimately decide what are the new trends in modern psychoacoustics by submitting interesting reports! We cordially invite you to submit your reports and look forward to inspiring topics for discussion!
