摘要：
A method of forming hardware percussion comprising the steps of performing short strokes by plessimetru which is disposed on the body, and registering the acoustic response of the impact microphone, the output of which a signal processing system with a fast Fourier transform and visualized in the amplitude-frequency coordinates, characterized in that pin is used as pulsed ultrasound (US) radiation, which is directed to plessimetr a plate, the outer side of which facing the ultrasound emitter to operate roughness to scatter the radiation, and the pulsed ultrasonic radiation pressure on plessimetr equivalent directional impact pressure, the duration of which is controlled from a minimum of 0.5 seconds, an acoustic feedback from microphone shot record that a contactlessly from the body, and the lower boundary of the recorded microphone 20 Hz frequency wherein the electrical response after conversion are in the linear coordinate system, amplitude-frequency spectrum in the form of the resonance curve, which is fixed on the Q of D resonances, and then a graph of the spectral curve is differentiated and the result is represented in the same coordinate system, the position of the resonance frequency fopredelyayut the passage differential curve through zero on the frequency scale, and the value Q spectral resonance curve shift along the frequency scale and shape change differential left curve and the right of ftekuschih percussive dimension compared with previous measurements and comparing the results give an estimate of the state of the organ being examined.Способ формирования аппаратной перкуссии, включающий в себя операции выполнения коротких ударов по плессиметру, который располагают на теле человека, и регистрации акустического отклика на удар микрофона, выходной сигнал которого обрабатывают системой с быстрым преобразованием Фурье и визуализируют в координатах амплитуда-частота, отличающийся тем, что в качестве удара используют импульсное ультразвуковое (УЗ) излучение,
