Classification: CPC A  H | IPC A  H

Claim 1:
2. A method of receiving and processing at least one auscultatory sound signal from a corresponding at least one auscultatory sound-or-vibration sensor as recited in claim 1, wherein the operation of determining whether or not said corresponding at least one auscultatory sound-or-vibration sensor is functioning properly comprises:
a. capturing said corresponding at least one auscultatory sound signal over a period of time;
b. calculating a Short Time Fourier Transform (STFT) for each of a plurality of windows of data within said period of time; and
c. calculating a corresponding average power corresponding to each of said plurality of frequency components from each of said plurality of windows of data, wherein the determination of whether or not said corresponding at least one auscultatory sound-or-vibration sensor is functioning properly is responsive to a comparison of said corresponding average power corresponding to each of said plurality of frequency components with at least one corresponding threshold.
