what for?
Acoustic analysis can be used to determine the health status and mood of the bees.
apidictor patent
frequencies to measure:
- 180-190 Hz ("normal"): healthy bee sound in quiet period (night?)
- ~220-290 Hz ( "warble"): if that sound occurs, queen's rate of egg laying has diminished.
- >3000 Hz ("hiss") : sound occurs by clapping or knocking on the hive.
- short sharp hiss: healthy queen
- sluggish rise in hiss with slow fade: abnormality
interpretation of the sounds
| warble | hiss | interpretion |
|---|---|---|
| yes | sluggish rise and fall, max intensy much less than normal. "at time of issue it has vanished" | swarming activity. possibly noticeable 15 days before swarming. |
| yes | short sharp hiss | age or deformity of the queen |
| yes | on hiss vanishes completly | death or removal of queen |
