I’m very excited to finally share our new PNAS paper! 🦇 🔈🧪 We show that freely flying, echolocating bats aim both ears at prey, sacrificing some binaural level cues to create a narrow acoustic field of view, boosting weak target echoes and increasing clutter rejection. www.pnas.org/doi/10.1073/...

Happy to share our new paper is now published! 🎉 We developed a non-invasive method to model animal hearing using 3D photogrammetry and showed it on bats 🦇 and a pig. It even allowed us to capture the 3D mesh of an alive and awake bat and model its hearing! 🔉 Article: doi.org/10.1111/2041... 🧪

3D photogrammetry as a low‐cost and non‐invasive method for acoustic modelling of animal hearing
Sound localization is important for all eared animals and the spatio-spectral cues for localization are described through the head-related transfer function (HRTF). Current state-of-the-art for ob...

Exciting. Tomorrow we will have a Python workshop with our bioacoustics research group that I helped organize. Anyone have some last minute advice what I definitely should mention? #Python #Bioacoustics

Happy to share the first article I was part of :) Have you ever wondered how velocity influences echolocation behavior of aerial hawking bats? We found when accounting for flight velocity the investigated species probed their environment in an equal manner. authors.elsevier.com/c/1kXK9_LsQS...

Velocity as an overlooked driver in the echolocation behavior of aerial hawking vespertilionid bats
Moving animals must gather information at sufficient rates, detail, and range relative to their velocity while filtering this information to that esse…

4 scientists wait for a bat to decide to feed so we can take video and audio recordings ... its a process 🤣
