What frequency do bees hum at?

Various researchers have reported the range of frequencies of the acoustic signals produced by a honey bee colony are in the range from 100 to 1 kHz [2,18], and that most of the sound have frequencies around 300, 410 and 510 Hz [9].

The buzzing sound we hear is because bees can flap their wings at a pretty impressive 230 beats per second . This rapid wing beat causes the air around the bee to vibrate and that vibration travels to our ear and we interpret that vibration as a buzzing sound.14 Eyl 2020

Bumblebees “can unhinge their wings from their wing muscles and vibrate their bodies,” Ellsworth says, making that buzzing sound you hear when they’re on a flower in the tone of middle C. “It’s the ‘hey’ in ‘Hey Jude ,’ and it causes the flower to explosively release pollen.”
