On the Room Acoustics of Two Reactivated Hypar Shell Buildings in Magdeburg and Templin
* Presenting author
Abstract:
Two historical buildings from the late 1960s / early 70s, protected monuments with double-curved roof shells shaped as hyperbolic paraboloids (Hypar) designed by the Rügen-based structural engineer Ulrich Müther, have recently been revitalized after approximately 30 years of vacancy and decay. These buildings now showcase impressive architectural restorations.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.This talk covers the history, architecture, and room acoustics design of these buildings, as well as the achieved acoustic quality of each project.
