Array calibration

Managing MEMs microphone calibration – MicrodB will share its findings at the 14th French Acoustic Congress in Le Havre from April 23rd to 27th

MicrodB will take advantage of the French Acoustic Congress in Le Havre to present its work on local MEMs microphone calibration and the integration of an associated filter to correct its response.

The democratization of information technologies and communication (ICTS) offers new possibilities for acoustic metrology, and more specifically methods implicating a large number of microphones. Digital MEMs sensors and embedded ARM FPGA processors provide a new solution for these situations, increasing performance while reducing implementation costs.

However, the integration of these technologies, which are not intended for metrology, requires rigorous calibration to identify and correct the intrinsic frequency response of the MEMs welded on an electronic board (PCB).
