Abstract:
1. Apparatus for detection of human falls, comprising: an acceleration detector, for detecting vibration events, the acceleration detector attached to a floor, and configured to sense low amplitude vibrations with accelerations up to 2 g; a microphone, for placing in association with said acceleration detector for detection of sound events, and a classification unit comprising an acceleration input for input of data relating to said vibration events from said acceleration detector and a sound input for input of data relating to said sound events from said microphone, the unit configured to classify separate events from said microphone and said acceleration detector respectively as concurrent events from said microphone and said acceleration detector, thereby to determine whether a human fall is indicated, wherein said microphone has a frequency range of substantially 20-16000 and an S/N ratio in excess of 58 dB.
