Flipper was a tv show in the 60s about a dolphin and his humans. There is this sound that flipper supposedly makes out of water that is unlike any other dolphin sound I have heard (I have studied underwater acoustics of pelagic dolphins for a long time). I have always wondered if this is a sound that dolphins may make in the air? Or perhaps they can be trained to make this sound? Or perhaps this sound is synthetic/fake?
Does anyone know if this is a real sound that dolphins make?
