Degraded part estimating apparatus, degraded part estimating system and degraded part estimating method

摘要

The deteriorated part estimating device (6) comprises a plurality of microphones (13₁13₃), And a short time Fourier transform unit (FFT) for acquiring the microphone signals (DS1, DS2, DS3) corresponding to each of the microphone signals (DS1, DS2, DS3) and calculating the time series of the short time Fourier transform coefficients corresponding to each of the microphone signals (31), a time series array generating section (32) for generating a time series arrangement for input to the neural network using a time series of short time Fourier transform coefficients, and a neural network, A neural network unit (35) for receiving an input and outputting a degree of deterioration corresponding to the examination target part in the examination target device, and a judgment unit (36) for judging a deterioration point in the examination target device using the deterioration degree.
