Mysticetes produce a great variety of sounds ranging in frequency from as low as 10 Hz to as high as 20 kHz. They have been classed based on their spectrographic features as tonal, frequency-modulated, amplitude-modulated, and pulsive. They have often been categorized based on what they sound like to the human ear (e.g., moan, grunt, screech, and boing). They might occur in rhythmic patterns (song) or as single, non-song sounds. In this chapter, we provide an overview of the sounds made by the various species of mysticetes. We discuss the likely functions of these sounds (e.g., as related to reproduction or foraging). We show long-term changes of some of these sounds over multiple decades and we summarize the demonstrated effects of noise on the acoustic behavior of mysticetes.

摘要

Mysticetes produce a great variety of sounds ranging in frequency from as low as 10 Hz to as high as 20 kHz. They have been classed based on their spectrographic features as tonal, frequency-modulated, amplitude-modulated, and pulsive. They have often been categorized based on what they sound like to the human ear (e.g., moan, grunt, screech, and boing). They might occur in rhythmic patterns (song) or as single, non-song sounds. In this chapter, we provide an overview of the sounds made by the various species of mysticetes. We discuss the likely functions of these sounds (e.g., as related to reproduction or foraging). We show long-term changes of some of these sounds over multiple decades and we summarize the demonstrated effects of noise on the acoustic behavior of mysticetes.
