It is abundantly clear from: o measurements of hearing in the laboratory, o sound output characteristics made in the field and in the laboratory, and o auditory morphology o that there are major differences in auditory capabilities across marine mammal species (e.g., Wartzok & Ketten, 1999). o Most previous assessments of acoustic effects failed to account for differences in functional hearing bandwidth among marine mammal groups and did not recognize that the ‘nominal’ audiogram might be a relatively poor predictor of how the auditory system responds to relatively strong exposures.Marine Mammal Hearing• [Southall, 2007] delineated five groups of functional hearing in marine mammals and developed a generalized frequency-weighting (called “M-weighting”) function for each. • The five groups and the associated designators are: – (1) mysticetes (baleen whales), designated as “low-frequency” cetaceans (Mlf); – (2) some odontocetes (toothed whales) designated as “mid-frequency” cetaceans (Mmf); – (3) odontocetes specialized for using high frequencies, i.e., porpoises, river dolphins, Kogia, and the genus Cephalorhynchus (Mhf); – (4) pinnipeds, (seals, sea lions and walruses) listening in water (Mpw); and – (5) pinnipeds listening in air (Mpa).
