To conduct focused research into bells, Kempten University of Applied Sciences established the European Competence Centre for Bells. The core elements are a large anechoic chamber, a materials science laboratory, and a dedicated team of staff. As part of a European research project, the Competence Centre has created and developed a wide range of measuring equipment, computers and analysis and simulation programs, which are used intensively in ongoing projects together with the required data on the solidity of bells.
ECC ProBell® examines church bells from the perspective of engineering science:

The bells of St Ursus Cathedral in Solothurn and the Reformed Town Church in Thun are currently being extensively overhauled and renovated. As part of this process, ECC-ProBell was commissioned to evaluate the condition of the bells and to suggest how to potentially limit damage as far as possible while producing high-quality sound.
In collaboration with the bell foundry H. Rüetschi AG in Aarau, the bell systems were evaluated using measuring equipment, including the stress loads during ringing, and the bells’ “fingerprints” were recorded. In line with pervious measurements taken of bells in Switzerland, it was found that the clappers generally installed during the decades following the Second World War frequently cause relatively high stress loads when the bells ring. It is also the case for the bells that we examined that action is needed to ensure less damage is caused during the ringing process and to improve the tonal resonance.
The “Pummerin” bell in St Stephen’s Cathedral was inspected in 2011 and then fitted with a low-risk clapper based on our calculations.
We fitted new clappers to the bells in Bern Cathedral, as the old ones caused stress loads during ringing that presented a high risk of damage and limited the quality of the sound produced.
The big bell in St Peter’s Cathedral in Rome and the Savoyarde in Sacré Cœur in Paris have both been inspected for damage.
