Summary
Scientists found that hedgehogs can hear sounds at much higher frequencies than humans, which may help in protecting them from dangers and understanding their communication. Researchers discovered this by testing how hedgehogs respond to different high-pitched sounds. The findings could lead to new ways to keep hedgehogs safe from hazards like cars and other machinery.
Key Facts
- Hedgehogs can hear up to 85kHz, much higher than the human limit of 20kHz.
- This high-pitched hearing ability could help hedgehogs communicate in ways humans cannot hear.
- The findings might help create sound devices to steer hedgehogs away from dangerous machines like cars and lawnmowers.
- Scientists conducted the research by playing sounds to hedgehogs and measuring their brain reactions.
- Hedgehogs are classified as near-threatened due to the risk of road collisions and other hazards.
- This research opens possibilities to use targeted sounds to protect hedgehogs without affecting humans or pets.
