Permanent Sound and Vibration Protection for Vienna's Musikverein Concert Hall (AT)

Consistently high protection against secondary airborne noise and vibrations

The acoustics of Vienna Musikverein's "Goldener Saal" hall are among the best in the world. In 2002, an underground railway tunnel was built just four meters (less than 14 ft) from the building. To avoid any disturbance of the listening experience for visitors to the Musikverein, a mass-spring system (MSS) with discrete Sylodyn® bearings from Getzner was installed beneath the railway bed when the underground line was built.

The challenge

Protection against noise and vibration immissions in Vienna's Musikverein building due to the subway service
250 trains per track and per day
High long-term performance of the mass-spring system
Siding for damaged trains: in addition to the mass of the slab, stationary train loads have also been exerting stress on the Sylodyn® bearings over extended periods of time
More emissions in the tunnel caused by the new V train type

The Getzner solution

The isolated floating slab sits on individual elastic Sylodyn® bearings spaced two meters (6.6 ft) apart. The natural frequency of the 100-meters (328 ft) mass-spring system is 5.5 Hz, the lowest vertical natural frequency ever achieved with an elastomeric mass-spring.

Advantages for customers

No noticeable noise or vibration immissions due to subway traffic
Constant spring characteristics of the mass-spring system with Sylodyn® point bearings even after 17 years of operation

” The one-of-a-kind 'Goldener Saal' demanded particularly careful planning, component selection, and implementation to satisfy the Musikverein's extremely stringent immission protection requirements. Dr. Andreas Oberhauser Superestructura, Responsable de departamento, WIENER LINIEN GmbH & Co KG
