Temporary threshold shift (TTS) was measured in a bottlenose dolphin (Tursiops truncatus) after exposure to 16-s tones at 3 and 20 kHz to examine the effects of exposure frequency on the onset and growth of TTS. Thresholds were measured approximately one-half octave above the exposure frequency using a behavioral response paradigm featuring an adaptive staircase procedure. Preliminary data provide evidence of frequency-specific differences in TTS onset and growth, and increased susceptibility to auditory fatigue after exposure to 3-kHz tones compared to data obtained two years earlier.
