🎧 Reading the Mood of the Hive

About this simulation

Beekeepers and researchers increasingly use microphones and accelerometers clipped inside a hive to track colony state without opening it. This simulation shows a simplified hive cutaway alongside a synthetic "sensor readout" — a scrolling waveform and a frequency-bar spectrum — that respond to the same underlying agitation level as the bees themselves. It is a model built to make the correlations intuitive, not a claim that bees experience mood the way humans do.

How it works

• Buzz frequency — a resting broodnest hum sits roughly around 200–250Hz; disturbance, queenlessness signals and pre-swarm congestion tend to push the dominant frequency and its harmonics higher, toward 300–500Hz.
• Sound level & vibration — wingbeat activity and wall-tapping/fanning increase both airborne sound and comb vibration together as more bees move faster and more erratically.
• Bee movement — orbit speed and jitter around the comb scale with the agitation value, and at high agitation a stream of bees pours out of the entrance, echoing a real swarm exodus.
• Real bioacoustic monitoring research (e.g. Bencsik & Newton's hive vibration studies, and pre-swarm "piping"/"quacking" sounds from queens) shows these signals correlate with colony state, but they are indirect proxies — not a direct read of insect emotion.

Controls

• Colony state preset — jumps straight to a modelled calm, alert, pre-swarm or swarming state.
• Agitation override — fine-tune the underlying 0–100 agitation value directly.
• Auto environmental drift — lets agitation wander slowly on its own, like ambient weather and forage changes would in a real colony.
• ⚡ Tap the hive — injects a short disturbance spike (like a knock or a passing vehicle) that decays back to baseline, similar to how real accelerometer traces show transient spikes.

Did you know?

Some precision-apiculture systems flag likely swarm preparation purely from acoustic and vibration trends — a rising, broadening frequency band plus a temperature and weight signature — days before a beekeeper would otherwise notice a crowded hive.
