Vibration measurements are performed in many disciplines, like mechanical engineering or civil engineering, to eliminate disturbing vibrations, prevent damage to structures and ensure the well-being of individuals.

In the development process of the app numerous comparative measurements were carried out to ensure the correct determination of the results. Here, ceilings, columns, bridges and their hangers were examined for their natural frequencies and the results of the myFrequency app were compared with those of professional measurement sensors. This resulted in maximum deviations of the frequency peaks of about 1.1%.
 
These studies prove that the myFrequency app is an adequate replacement or supplement to costly professional measurement sensors.

Comparative measurements of hanger of the Frey Bridge in Berlin, Germany

At the Frey Bridge in Berlin, the natural frequencies of hangers were determined. They were measured on the one hand with the myFrequecy app and on the other hand with professional accelerometers. Both "gauges" were installed on a hanger.

The comparitive measurements on the hangers showed maximum deviations of the frequency peaks of only 0.09%. With the help of the app myFrequency, the costs and the time required to determine the natural frequencies of hangers can be reduced enormously (see below).

Comparison / conclusion

The comparative measurements showed that the myFrequency app is an adequate alternative to expensive measuring technology, since time and costs can be saved on a large scale. In the case of the measurement of the natural frequencies of hangers, a reduction of the time effort by about 96% can be achieved, with the same measurement result.
