Evidence of a Lombard response in migrating humpback whales (Megaptera novaeangliae) [PDF]
The Journal of the Acoustical Society of America, 2014 The Lombard reflex is an increase in the subject's vocal levels in response to increased noise levels. This functions to maintain an adequate signal-to-noise ratio at the position of the receiver when noise levels vary. While it has been demonstrated in a small number of mammals and birds including some whales, it has not yet been shown to occur in one
