The Fossil Forum In a new study, scientists at the Smithsonian's National Museum of Natural History did just that. Sperm whales ( Physeter macrocephalus, Linnaeus, 1758) are one of the deepest diving toothed whales that produce sounds with extreme loudness greater than 180 dB re 1 Pa, have exceptional frequency discrimination abilities and an estimated best hearing sensitivity from 0.1 to 30 kHz with frequencies of 2-4 and 10-16 kHz close to maximum energy [ They typically shatter to pieces in the mine. They have a pad of fat to enhance these vibrations for the tiny ear bones (tiny relative to the massive size of the whale). Captcha failed to load. On the other hand, toothed whales use fast, high-pitched clicks and whistles that have different frequencies depending on the individual whale, dolphin, or porpoise that is communicating.
