From 17-20 March, in the beautiful city of Copenhagen, ADA-AMC (a WSDG company) will participate in the first joint annual meeting of the German and Danish Acoustical Societies, DEGA and DAS. Tobias Behrens and Wolfgang Ahnert will deliver a talk about two historical buildings from the late 1960s and early 70s – protected monuments with double-curved roof shells shaped as hyperbolic paraboloids (Hypar). These structures, designed by the Rügen-based structural engineer Ulrich Müther, have recently been revitalized after approximately 30 years of vacancy and decay.
The Hyparschale Magdeburg, formerly an exhibition and event hall, features a column-free floor space of over 2,300 m2. Its roof comprises four Hypar shells, creating an interior volume exceeding 23,000 m3, where acoustics have been designed to accommodate congresses and cultural events for up to 500 guests. The Hyparschale Templin, originally a dining hall in a GDR-era vacation complex, boasts a column-free Hypar roof spanning approximately 480 m2. This hall is part of a newly renovated complex that includes a daycare center, administrative offices, and a restaurant, and is now used for cultural events and seasonally as an ice-skating rink.
The talk, titled “On the Room Acoustics of Two Reactivated Hypar Shell Buildings in Magdeburg and Templin,” will explore the history, architecture, and room acoustics design of these buildings, as well as the achieved acoustical quality of each project.
