Blue Whale Balaenoptera musculusīlue whale species profile | Low-frequency sound played at 8x normal speed.Prices and availability of products are subject to change without notice. These sounds are usually made in the context of mating, competition for food or territory, contact calling, or general social communication. Mysticetes (Baleen Whales)īaleen whales generally make low-frequency (0-5kHz) sounds. The loudness of a sound can be seen by the color scale of the sound in the spectrogram, with lighter colors implying louder sounds. Time here is measured in minutes and seconds, in the format mm:ss. Time is shown along the bottom of the graph (the x-axis). ![]() ![]() Frequency is most often measured in hertz (Hz) or kilohertz (kHz). The frequency of the sound is labeled on the vertical or y-axis. Sounds in the Ocean: Fish and InvertebratesĪ spectrogram is a visual way to display sound. Sounds in the Ocean: Environmental and Anthropogenic.Some sounds (in particular from mysticetes/baleen whales) are very low frequency, and you may need high-quality speakers to hear the recording. Note: You can click on any of the photos and spectrograms on this page to view and/or save the full image. ![]() Scientists in the Northeast's Passive Acoustic Research Group and their colleagues have compiled these sounds to provide examples of the variety and breadth of animal sounds. Passive Acoustic recorders can be towed behind a ship, mounted on mobile ocean-going robots, or placed at specific underwater sites and left out for days, months, or even years, capturing that location’s soundscape until the recorder is retrieved. Changes in the rate, pitch, and/or structure of sounds communicate different messages. ![]() Sounds are particularly useful for communication because they can be used to convey a great deal of information quickly and over long distances. They depend on unique adaptations to communicate, locate food, navigate underwater, and/or understand their environment. Many marine animals rely on sound for survival. Underwater sounds provide information about the surrounding environment-or soundscape-such as what marine animals are present or what human activities are taking place. ![]()
