In the night health care active acoustic monitoring is beeing often used. With acoustic monitoring, residents, clients and patients are actively given out and the status of their well-being monitored. 
These systems monitor patients by continuous analysing sounds in different areas. When exceeding a noise threshold in a room, the call to the night care center will be made, where residents can be listened by health care professionals. 

Current systems
The advantage of this system is that multiple sites from a central point is given out and gives an enormous effectiveness. The disadvantage of current systems is that many false alarms come through and require unnecessary response of health care professionals. 
These systems operate on the the basis of a volume threshold (AM1), and, where appropriate added by setting a time delay (AM2), and patient depending adjustments can be made. It is also not known how many care-related sounds such as blowing, snoring, teeth grinding, etc. that do not exceed the volume alarm are being missed. 

With our system (AM3) generic sounds like rain on skylights, passing vehicles, walk across the hall, pulling a toilet can be detected and optionally filtered out. Our solution also works independently and recognises client specific sounds: snoring, breathing, teeth grinding, etc., if desired, and can be passed to the (night)care center. 
A true revolution for healthcare, which more than 50% of false alarms can be filtered out!
