For the frequency range above 20 kHz, there is no clear and complete information on the factors influencing the result of a measurement of sound pressure level. Moreover, there are no current international standards for performing measurements of ultrasound at work stations. The authors presents a possibility for the adaptation of the existing measurement methods, in particular, the requirements for measuring instruments, procedures to be followed while performing measurements, the application of a correction to measurement results, and the determination of measurement uncertainty. The development of a consistent method of ultrasound measurement is of utmost importance in carrying out an assessment and reducing the risk of exposure to this physical factor in the work environment.
