|Acoustic Monitoring Program: Sounds (examples)|
Low-frequency sound in the ocean can be "viewed" in the form of time versus frequency "spectrograms" (warm colors represent strong energy) or "listened to" if the natural sound is raised to human hearing by "speeding up" the original signals. These sample sounds represent seismic and biological sources, as well as sounds of unknown origin.
