Airborne ultrasound noise in the workplace is an increasing problem concerning occupational safety and health. Industry applications found most frequently are cleaning, cutting and welding. National regulations exist, non-consistently providing limit or guidance values and a few giving weak advise on the measurement procedure itself. But in general, ultrasound noise measurement struggles with several basic problems, e.g. lack of instrumentation, traceability, tailored procedure and even knowledge on the impact on humans. Among other issues, the EARS II project, funded by the European metrology programm for innovation and research (EMPIR) of EURAMET, addresses the development of an appropriate measurement procedure for the assessment of noise at the work site. In the daily business of occupational health and safety engineers, there is no time for intensive studies. Thus, a reference workplace has been set up in the laboratory to examine soundfields in detail. These studies give a detailed view into the specific characteristics of ultrasound fields and allow to derive an adequate and practicable measurement procedure for ultrasound noise assessment. The talk will present the development of a revised measurement procedure for the assessment of ultrasound noise at workplaces and the findings on the influence of the worker's torso on the result.
