DAS | DAGA 2025 marks the seventh in the series promoted by DEGA to encourage cooperation and exchange across borders. Following Austria, Switzerland, France, the Netherlands and Italy, we are pleased to extend this horizon to a Nordic country. Organizing this collaborative event is particularly exciting. The conference will be in the spirit of the rich Danish tradition in Acoustics. It is almost impossible to mention acoustic measurements, hearing aids, loudspeakers, or room acoustics without acknowledging the strong visibility of both the Danish industry and the country's scientific community.
