Patent Images
1. A sleep apnea syndrome diagnosing device, comprising:
- 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.
