Since its introduction in the late first half of the twentieth century, the use of ultrasonic appliances for various industrial applications has increased. Along with this growth in dissemination, the exposure of workers to airborne ultrasound also increased. In this paper we present the analysis of two data sets comprising 131 measurements at ultrasound associated workplaces in Germany. The data sets were individually acquired by the Institute for Occupational Safety and Health (IFA) and by the German Social Accident Insurance Institution for the energy, textile, electrical and media products sectors (BG ETEM). The data were analysed for abundance of certain machine categories and for transgression of threshold values according to German national guidelines. Machine categories were formed by combining machine type and working frequency. The results show that threshold transgressions occur at a considerable amount of workplaces at ultrasonic welding machines of certain frequencies. © 2018 The Author(s). Published by S.
