Abstract

The measurement methods and occupational exposure limits for ultrasonic noise (airborne ultrasound) are described. Typical sources of ultrasonic noise and sound pressure levels measured at workplaces are discussed. The verified Polish regulations on maximum admissible intensity (MAI) values for ultrasonic noise in the work environment and proposals of exposure limits for workers at particular risk (i.e.pregnant women and juveniles) are presented.

Key words
