Extract intracorporeal sounds (such as low-frequency-range heart sounds or breath sounds) by not only reducing steady noise (such as low-frequency-range environmental sounds or noise) but also reducing unexpected noise (such as high-frequency-range cries or speaking voices). This keeps up the intracorporeal sounds (such as low-frequency-range heart sounds or breath sounds), while reducing the unexpected noise (such as high-frequency-range cries or speaking voices), using an improved adaptive filter unit and an improved nonlinear filter unit. Here, a reduction level of the unexpected noise (such as high-frequency-range cries or speaking voices) and a level of keeping up the intracorporeal sounds (such as low-frequency-range heart sounds or breath sounds) are quantitatively calculated.
