The hum inside beehives are being recorded to try to keep an ear on the insects' health.
Special devices, which monitor the sounds the bees make when they're working and resting, are being put in hives across Scotland.
Bees are thought to make different sounds depending on what they're doing and how they're feeling.
So it's hoped the new recordings can help tell us what the bees are up to and if they're well or not.
Scientists will also use the information to investigate why numbers of bees and pollinating insects in the UK are falling.
Although bees don't have ears, the hum is thought to be very important to the co-ordination of hive activity.
