| Beskrivelse |
Sound Spectrum of a Humpback Whale (Megaptera novaeangliae). English: "In the example[s] shown here, time increases up the page and frequency increases to the right. Using spectrograms, a trained analyst can determine the nature of the received sound (in most cases)."
Français : Spectre sonore d'une baleine à bosse (Megaptera novaeangliae). Description originale: "Dans les exemples montrés ici, la fréquence augmente vers la droite. A l'aide de spectrogrammes, un analyste confirmé peut déterminer la nature du son reçu (dans la plupart des cas)."
