DAGA 2023 in Hamburg – 49th Annual Conference on Acoustics
The 49th Annual Conference on Acoustics DAGA took place from March 6th to March 9th 2023, in Hamburg. The IHTA was represented there with 22 presentations and seven posters. The researchers presented their work in eleven different subject areas. This shows the broad range of topics the Institute covers in hearing technology and acoustics.
During the conference, the technical committees of the Deutsche Gesellschaft für Akustik e.V. (DEGA) met. In the technical committee Hörtechnik (Hearing Acoustics) Professor Janina Fels handed over the chair position after six years. Besides, the technical group Junge DEGA selected Simon Kersten as its new chairman. Jonas Heck, who was elected as deputy, supports him in this position.
After the dinner at the social evening on Wednesday, the IHTA Band performed two songs from their repertoire. On Thursday, a small group took the opportunity to participate in an excursion to the Elbphilharmonie. Not only the grand hall was visited, but also the rooftop was climbed.
