摘要： An apparatus for observing a sound field of an ultrasonic wave, including a first unit which determines characteristic values (B/A).) of a medium at each point of a predetermined region by an ultrasonic wave having a sound field of an arbitrary form and a second unit (18) which displays an output of the first unit as two-dimensional or three-dimensional distribution (20) in the predetermined region, enabling control of the form of the sound field (16) of the ultrasonic wave.
