1. A device for monitoring and analyzing breathing sounds, the device comprising:
- at least one microphone placed adjacent a body to be monitored for contactless recording of breathing sounds;
a motion detector to detect motions of said body;
a processor coupled to said microphones and said motion detector for receiving and processing said breathing sounds and concurrent detected motions to detect abnormal breathing events.
