Als Wandverkleidung dienen Schlitzplattenabsorber. • Slit panel absorbers serve as wall cladding.

Die Glasfront ist eine akustische Herausforderung – textile Oberflächen und diverse Akustikelemente schaffen den Ausgleich. • The glass front presents a particular acoustic challenge – surfaces and acoustic elements are a counterbalance.
