subject experienced a 7-dB MTTS after exposure to a 10-kHz tone of 192 dB re 1 µPa. Both<br />
subjects had MTTSs of 6–12 dB following 20-kHz tones at levels between 197 to 201 dB re 1 µPa.<br />
Neither subject experienced an MTTS after exposure to 0.4 kHz tones up to 193 dB re 1 µPa.<br />
Deviations in the whales’ trained behaviors were observed following exposures that ranged<br />
from 180-196 dB re 1 µPa at all four exposure frequencies.<br />
