ABSTRACT:
A sleep apnea syndrome diagnosing device disclosed herein comprises: a snoring sound collector which collects snoring sound; a snoring sound holder which holds the collected snoring sound; a correlation coefficient calculator which divides a time axis of the snoring sound held in the snoring sound holder into plural cycles and which sequentially calculates a correlation coefficient between the snoring sound of one cycle and the snoring sound of a cycle next to the one cycle; and an output section which outputs the correlation coefficient calculated by the correlation coefficient calculator.
