IOMAC is the first conference on the subject of Operational Modal Analysis (OMA). The idea of IOMAC is to be the natural meeting place for everybody in the field - the scientist, the applicant, the vendor and the student, and also those who would like to get introduced to the field. IOMAC is a non-profit initiative between the organizers, re-investing possible profits in new conferences, education and literature in the field of operational modal analysis.
