Fecha de publicación: 11/03/2010 Fuente: WIPO "beekeeper" A method of and system for using sounds produced by bees flying near a beehive entrance enable a beekeeper to assess the operational productivity of the beehive. In a preferred embodiment, the method entails positioning an acoustic pickup device, such as a microphone, at a location to pick up and provide an audio signal representing sounds produced by bees flying around the beehive entrance. The flying bees produce the sounds either while hovering in the vicinity of the beehive or while launching from locations around the beehive entrance to forage for pollen and nectar. The audio signal is analyzed to distinguish the sound of launching flying bees from the sound of ambient background noise.
