Site Installation and Trials of the Acoustic Monitoring System Soundprint (AGB2002/009)
Overview
Background & policy context:
Soundprint was developed in Canada and is distributed in Europe by Advitam. Sensors, systematically attached to the structure register and localize energy induced by wire breaks and transferred through the structure as oscillation. Since every oscillation got a characteristic spectrum irrelevant data can be filtered out. The analysis and interpretation is done by a special software. Thus wirebreaks can be detected and subsequent wire breaks or deterioration can be controlled.
Objectives:
The acoustic monitoring system Soundprint will be applied to a structure under site condition and scientific attendance for the first time in Switzerland. The system will be tested and evaluated under continental European and alpine conditions.
Artificial signals with and without correlation to post-tensioning will be generated in a blind trial arrangement and the diagnostic skills of the system will be tested. Deliberately created and spontaneous occurring wire breaks are supposed to be identified by the system. Other events not evident for the structural resistance will be filtered out.
Methodology:
In this project will be used as a crucial method field trials.
