How does deep-sea sound like?

Deep-sea sound is characterized by low-frequency, long-wavelength noises that can travel vast distances underwater. It includes natural sounds from marine life, such as whale calls and the clicks of sonar from dolphins, as well as geological noises like underwater earthquakes and volcanic activity. The environment is often described as eerily quiet, with occasional deep rumbles or distant echoes, creating a unique acoustic landscape that differs significantly from sounds found in shallower waters.
