Laboratory based experiments, without bees, have demonstrated that the transmission of vibrations in foundation and built comb and through the timber frame and brood box are complex and evolve through the life of a colony.
Accelerometers placed in the comb, on the wooden frame of the comb and on the wall of the brood box can all provide useful vibrational data.
We have demonstrated that accelerometers provide measurements that originate both from acoustic noise and vibration signals.
The contribution of each component changes with sensor location.
A brood box with accelerometers situated on frames and combs and in the brood box wall has been populated with bees and has been constantly monitored throughout the 2014 swarming season.
