It was good to see at the DAGA2022 that a lot of useful acoustic research has again been done in recent years. This underlines the importance of being able to live and work in a quiet environment. The presentations ranged from fundamental to applied research. Much research relates to the use of lighter materials. With which higher sound insulation can be achieved. As Metecno, we are proud to be part of this acoustic family and contribute to a quieter environment.
