Describes: - a method of determining the total emitted acoustic power of ultrasonic transducers based on the use of a radiation force balance; - general principles for the use of radiation force balances in which an obstacle (target) intercepts the sound field to be measured; - limitations of the radiation force method related to cavitation and temperature rise; - quantitative limitations of the radiation force method in relation to diverging and focused beams; - information on estimating the acoustic power for diverging and focused beams using the radiation force method; - information on assessment of overall measurement uncertainties.
