Some indirect evidence exists for multiple sonar signal generators in odontocetes. Direct evidence was collected from two bottlenose dolphins by simultaneously measuring and digitizing internal nasal cavity pressure, nasal tissue motion, and acoustic pressure. Small catheters measured pneumatic pressure changes at the same depth within each bony nasal passage. A high‐speed video endoscopy system revealed tissue motion at both pairs of phonic lips while two hydrophones measured acoustic pressure… CONTINUE READING
