Underwater playback schematic. In the playback paradigm, the sound source is played from an underwater Lubell Labs™ LL16 speaker 0.5–1.0 m from the dolphin’s head to ensure appropriate playback sound levels to the subjects. The sounds are initiated when the target dolphin self-separates from conspecifics and crosses the playback line. Swim direction is indicated with the arrow.
