A portable electrophysiological data collection system was used to assess hearing in a captive population of bottlenose dolphins by recording auditory evoked potentials (AEPs). The AEP system used a transducer embedded in a suction cup to deliver amplitude modulated tones to the dolphin through the lower jaw. Evoked potentials were recorded noninvasively using surface electrodes. Adaptive procedures allowed hearing thresholds to be estimated from 10 to 150 kHz in a single ear in about 45 min… CONTINUE READING
