Here are some additional links: Eddie Woods work by Rex Boys. ![]() I'm looking forward to hearing some warbling as we move into spring in summer. I also recorded to hives in the 250 hz frequency and did not hear any warbling. This makes sense as it is still winter here in Portland, Oregon and there should not be any preparations for swarming. Out of about 9 knocks I would get 3-4 strong hisses and more hisses could be detected after further sound amplification on the PC using the free software Audacity (its awesome). I was able to record two different hives in the above 3,000 hz range and the knocks were followed by a nice audible hiss in most cases. This could mean the queen is dead or the hive is preparing to swarm. There is a lot of interesting information in the article by Rex Boys. ![]() Eddie associated the warble with a non-laying queen.

The hiss occurs above 3,000hz after knocking the hive with an open hand. This article by Rex Boys details his invention and theories.Įddie described a 'hiss' and a 'warble' occurring at different frequencies. dedicated to predicting SWARMS! - Įddie Woods lived and studied in England. I worked with James Moore on his iphone App. Using the iphone app n-track and a $5 mic from office depot I was able to filter the audio to required frequency band and listen for the sound indicators. The warble occurs at around 250hz and is an indicator of hive problems.Įddie associated a sharp hiss as a happy hive and associated the warble with a non-laying queen and/or a hive that maybe preparing to swarm. Swarms are a means of bee's reproduction but they drive bee keepers nuts.Įddie described a 'hiss' and a 'warble' occurring at different frequencies. There are tons of beehives in my community and I wanted to get involved so I studied Eddie's work and applied an iphone app. I came across an article about Eddie Woods and his acoustical swarm detection machine, the Apidictor.
