Apidictor
From Infogalactic: the planetary knowledge core
An apidictor is an instrument which measures and records the sound in a beehive. The instrument records the aggregate sound made by the buzzing of the bees' wings. They were thought to be useful for predicting when a colony is preparing to swarm.
E.F. Wood invented and patented the apidictor in 1964. Only 300 are reported to have been sold.
