1. A processing apparatus comprising processing circuitry configured to:
acquire first subject data including a fundamental wave signal and a harmonic signal of an ultrasound wave;
input the acquired first subject data into a trained model; and
acquire second subject data output from the trained model, the second subject data corresponding to data in which an amplitude of the fundamental wave signal of the ultrasound wave included in the first subject data is reduced and which is based on an amplitude of a harmonic signal of the ultrasound wave included in the first subject data which is increased,
wherein the trained model is a model that has been trained, based on input of first ultrasound wave data, to output second ultrasound wave data corresponding to data in which an amplitude of a fundamental wave signal included in the first ultrasound wave data is reduced, and which is based on an amplitude of a harmonic signal included in the first ultrasound wave data which is increased.
