Almost 500 researchers, scientists, and PhD students from all over the world had registered for the International Symposium on Auditory and Audiological Research (ISAAR) which this year was held online on August 23-27. The topic of ISAAR 2021 was “The auditory system throughout life - Models, mechanisms, and interventions.”

This topic was considered  from different perspectives, including current physiological concepts, perceptual measures and models, electrophysiology and neuroscience approaches, as well as implications for hearing devices and new technical applications. Besides the topics related to the main theme, contributions covered a wide range of other areas within auditory and audiological research, including perceptual and physiological measures of auditory function, measures of hearing loss, auditory modeling, hearing-instrument signal processing, aided outcome measures, multi-sensory speech perception, communication in complex environments, advances in neural imaging for auditory experiments and cognitive auditory neuroscience.

In addition to the invited podium speeches, there were different zoom sessions streamed in parallel with time for panel discussions at the end of each session. All presentations were given live which provided an open atmosphere for questions and discussions. The quality of the presentations was very high and the general feedback from the participants has been particularly positive.
The next ISAAR conference will take place in two years from now, in August 2023, and will most likely be a ‘traditional’ physical meeting again.

ISAAR was supported by GN Hearing. More information about ISAAR, this year’s program and all abstracts can be found at
