摘要： In an apnea detecting apparatus, a respiratory pace analyzer determines a respiratory pace of a user based on an ambient noise (including a breathing sound, a snore, and the like of the user) generated in a surrounding area and on information of a posture of the user in determining whether or not the user suffers from the apnea syndrome. Then, an apnea time extracting unit in the apnea detecting apparatus determines whether or not a silent time is included in a time period during which the user is estimated to be breathing based on the respiratory pace and the silent time in the ambient noise.
