Advantages and disadvantages of radiation force balance and the thermocaoustic sensor.

	Advantages	Disadvantages
Radiation Force Balance	A benchmark technique with minimal measurement uncertainty in a vibration-free environment Versatile for a range of transducers in a wide intensity range	Cannot provide accurate measurements with noise vibrations Added complexity when measuring individual transducers in a transducer array High cost
Thermoacoustic Sensor	Measurements not affected by noise vibration An easy-to-operate device for measuring individual transducers in a transducer array Low cost	A calibration process is needed for a particular transducer Designed for low intensity ultrasound
