초록

The whistle sounds of three Beluga whales Delphinapterus leucas were recorded four times, for an hour each time, in2016 and analyzed to obtain the most stable and basic acoustic characteristics of the whales in captivity. This studyinvestigated the whistle characteristics of beluga whales and the relationship between whistle sounds and behavior tounderstand the meaning of the whistle sounds. The whistles were classified into six types (flat, ascending, descending,hump, dip, and wavy type) by their frequency contour and shape. The most common type was the ascendingtype, accounting for>30% of total whistles. The fundamental frequency of whistles was 2.0-8.6 kHz. Four types ofbehavior were related with the sounds of beluga whales (aggressive, submissive, affiliative, sexual behavior). A flatwhistle was the most recorded in the group and an aggressive act was observed in association with the flat whistle. Adip whistle were recorded more when submissive acts were observed.
