Bottlenose dolphins produce a myriad of sounds, some of which can only be heard with sophisticated recording devices.
The SDRP has accelerated the study of dolphin acoustics with the wild dolphins. During health assessments SDRP collaborators have conducted unique acoustic and communication research with wild dolphins.
Because we briefly capture and release dolphins for health assessment studies, we can assess the hearing ability of individual wild dolphins in the same way as is done with human infants.
Researchers also record dolphin sounds, and conduct sound playback experiments to the dolphins to try to learn more about dolphin communication.
Visit Dolphin Sounds to learn more and to hear samples of dolphin sounds.
