Seismo Wave Company is ongoing improving metrological processes and quality surveys to guarantee the best Infrasound sensors technology. In accordance with our quality approach, a running-in step for infrasound sensors has been investigated and implemented. Once the metrology process is completed (acoustical and electrical calibration, self-noise measurement), objective is to keep monitoring on sensitivity of MB3a sensors during several days, using the in-situ electrical calibration capability. For this purpose, a new bench has been designed and characterized in our laboratory. Different sensitivity assessment methods have been compared. Testing conditions, bench design, methodology and results are laid out in this poster.
