Work on beluga whale hearing in which either a 32 or 45 kHz tone was presented prior to a loud 32 kHz tone showed that either warning tone caused the whale to dampen its hearing in anticipation of the loud sound. This response was quickly learned within a single day but took three days to extinguish when the loud sound was removed. This work, presented at the recent SMM meeting in San Francisco, is now available as a publication in the Journal of Comparative Physiology A. DOI.
