IEA HPT Annex 63 Meeting in Aachen
On October 23rd to 24th, 2024, the participants of the IEA HPT Annex 63 project met in Aachen for their first in-person meeting, hosted by RWTH Aachen University and HEAD Acoustics GmbH. Annex 63 is part of the International Energy Agency’s Heat Pumping Technologies initiative, focusing on the Placement Impact on Heat Pump Acoustics. The Annex 63 includes groups for five task areas: Building Acoustics Impact of Heat Pumps, Urban Acoustics Impact of Heat Pumps, Psychoacoustics of Heat Pumps, Digitally Assisted Heat Pump Placement, and Dissemination. During this fourth working meeting, all task groups presented their current status and opened up for discussions.
Our Institute is mainly involved in the third workgroup (Psychoacoustics of Heat Pumps), where the contents are closely linked to our research project LowNoise, in which the acoustic emissions of air-to-water heat pumps are investigated.
Besides the lively exchanges, the project members also got the chance to see the laboratory at HEAD Acoustics GmbH, as well as at the Institute for Energy Efficient Buildings and Indoor Climate and the Institute for Hearing Technology and Acoustics of the RWTH Aachen University. Thanks to everyone involved for their contributions, and a special thanks to Christoph Reichl from the Austrian Institute of Technology for organizing this interesting initiative, aiming to improve the noise impact of environment-friendly technologies such as heat pumps.

1st IHTA Retreat
An interchange for good teamwork between researchers
On 28th and 29th March 2023, the scientific staff of IHTA was on a retreat at Gut Hohenholz near Bedburg in the Rhein Erft Kreis. During these two days, the institute’s past was reflected, and it was discussed how the future of the IHTA can be shaped together. Moreover, there was an intensive exchange among each other’s scientific work in the form of poster sessions. The researchers presented each other’s projects and revealed which milestones needed to be reached to achieve specific goals. Between poster sessions team spirit was strengthened, and the future of teaching and workflows were addressed. Furthermore, it was discussed how the skills of individual researchers could be maintained and passed on to new staff members.
Overall, it was two successful days with a lot of input for each individual and a lot of output for the group at IHTA.
A big thank you to Joachim Bellut, who guided us through the two days with his great moderation!

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.

ACOUCOU: Development of web-based teaching materials for acoustics
More than one year ago, the polish company KFB Acoustics initiated a Strategic Partnership involving four European universities (KU Leuven, University of Le Mans, University of Zagreb and RWTH Aachen University) and two companies (HEAD Acoustics and KFB Acoustics), funded by the Erasmus+ program of the EU, with the goal to develop ideas and concepts for the implementation and extension of an online teaching portal including various courses on acoustics. This portal, called ACOUCOU, short for Acoustic Courseware, is available on www.acoucou.org and currently contains one course about Vibroacoustics and example materials from the previous project Acoustics for Industry (ACI).
At the end of October, two ITA employees participated in the final meeting in Wroclaw, Poland, where the outcomes of the project and future events related to the ACOUCOU platform were discussed. The most recent event, an interactive session on educational materials in acoustics, which took place at the ICA conference in Aachen, was rated as a great success by all participants and led to new contacts and helped to disseminate the teaching portal.
The project consortium is also happy to announce that additional funding was granted by the EU to fill the teaching portal with more course contents in a three-year project starting in 2020. This project is named Acoustics Knowledge Alliance (ASKNOW) and is part of the Erasmus+ Knowledge Alliance program.
