The IDS is very pleased about the visit of Nicolaas Bernardus Roozen (KU Leuven) and Suhaib Koji Baydoun (TU Munich). As part of the Priority Program 1897 (funded by the German Research Foundation), our institutes are co-supervising a Master''s thesis on "Experimental Determination of Attenuation by Sound Radiation". The investigations will take place in the brand new fully anechoic room of the IDS.
