Thirty years of vibration protection for the Philharmonic Hall at the Gasteig
Long-lasting quality of under ballast mats — even under extreme conditions
- Vibration protection for the “noise sensitive” philharmonic hall
- Daily load of around 150,000 metric tons
- A variety of environmental influences
The Getzner solution
When the cultural centre was built in 1983, the builders had to ensure that the background noise level in the concert hall did not exceed the specified limit of 25 decibels when a train passed, so that the concert hall could also be used for recording.
To protect the noise-sensitive cultural centre from structure-borne noise emissions, the under ballast mats from Getzner were installed in 1983 over a distance of 345 metres.
Since 2013 we have discovered just how effective the Getzner under ballast mats are in the long-term: the products have been reducing the vibrations on this important route for around 30 years –and in turn the maintenance costs have reduced. The under ballast mats successfully reduce the structure-borne noise when a train passes through; the acoustic performance remains sound even today.
«All the tests indicate that our under ballast mats will remain effective for at least another 30 years. If we take the standard track service life of 50 years for our calculations, then we can be sure that the under ballast mats will remain effective throughout and beyond this period», says Mirko Dold, Product Manager at Getzner.
