Hedgehogs are in decline all over Europe. These prickly little fellas are faced with so many threats – in their rural habitats, in our gardens, and on our roads. But new research about hedgehog hearing could help us protect these adorable creatures from going extinct.

As part of our Science of Sound miniseries, we speak to Dr Sophie Lund Rasmussen, a scientist who has dedicated her life to hedgehog research and conservation. Also known as Dr Hedgehog, she’s a research fellow at the University of Oxford, and assistant professor at the University of Copenhagen.

Sophie tells us all about hedgehogs – what she loves about them, and how we can do our bit to help them thrive. She also explains her recent study on ultrasound, which she hopes could significantly reduce encounters between hedgehogs and cars.
