Key Findings
- In a study at Aarhus University, bats faced noise that hindered their echolocation but didn't rely more on vision
- Bats increased their echolocation call volume in noisy conditions, showing a consistent Lombard response
- Despite noise and light, bats didn't change their echolocation strategy, suggesting a hard-wired behavior
