A series of controlled measurements in a hemi-anechoic chamber is used to determine both acoustic impedance and the scattering coefficient. The experimental setup involves angled sound incidence and a fixed arc of microphones to capture reflected signals. A central goal is to develop a method that enables the simultaneous measurement of both parameters using the same configuration. Results from different approaches are compared to assess measurement accuracy and consistency. The findings contribute to more precise acoustic predictions in fields such as architectural and environmental acoustics. The presentation will be given in English.<\/p>\n<p><em>DE: Messung von akustischen Oberfl\u00e4cheneigenschaften<\/em><\/p>\n<p><em>Diese Arbeit untersucht die akustischen Oberfl\u00e4cheneigenschaften verschiedener Bodenmaterialien mit dem Ziel, die Genauigkeit akustischer Modelle zu verbessern \u2013 insbesondere in Umgebungen, in denen Bodenreflexionen das Schallverhalten ma\u00dfgeblich beeinflussen. Eine Reihe kontrollierter Messungen in einem halbhallfreien Raum dient zur Bestimmung der akustischen Impedanz sowie des Streukoeffizienten. Der Versuchsaufbau nutzt Schalleinfall aus verschiedenen Winkeln und einen festen Mikrofonbogen zur Erfassung des reflektierten Signals. Ein zentrales Ziel ist die Entwicklung einer Methode, die die gleichzeitige Messung beider Parameter mit demselben Aufbau erm\u00f6glicht. Die Ergebnisse verschiedener Ans\u00e4tze werden verglichen, um die Messgenauigkeit und Konsistenz zu bewerten. Die Erkenntnisse leisten einen Beitrag zu pr\u00e4ziseren akustischen Vorhersagen in Bereichen wie Bau- und Umweltakustik.
