[6] [7] The sperm whale uses echolocation and vocalization with source level as loud as 236 decibels (re 1 μPa m) underwater, [8] [9] the loudest of any animal. [10] It has the largest brain on Earth, more than five times heavier than a human's. Sperm whales can live 70 years or more. [11] [12] [13]
Although the theory is no longer consistent with experimental data, the paper itself served as a significant inspiration for studies in odontocete bioacoustics and in the experimental approach to testing the hypothesis a number of significant findings were made, including the loudest sound pressures ever measured from any animal (from sperm ...
Sperm whales, Sharma said, also use a two-level combination of features to form codas, and codas are then sequenced together as the whales communicate. The lower level has similarities to letters ...
Scientists studying the sperm whales that live around the Caribbean island of Dominica have described for the first time the basic elements of how they might be talking to each other, in an effort ...
Blue whales stop producing foraging D calls once a mid-frequency sonar is activated, even though the sonar frequency range (1–8 kHz) far exceeds their sound production range (25–100 Hz). [2] Moreover, there is evidence that blue whales stop producing foraging D calls once a mid-frequency sonar is activated, even though the sonar frequency ...
Researchers of chatty creatures like bats, bees, songbirds and whales gather many hours of sound or video recordings and then plug that data into AI language models, the way we might with tools ...
The final unit is a long (28.5 ± 1.6 s) tone that sweeps from 108 to 104.7 Hz. [11] The blue whale call recorded off Madagascar, a two‐unit phrase, [12] starts with 5–7 pulses with a center frequency of 35.1 ± 0.7 Hz and duration of 4.4 ± 0.5 s followed by a 35 ± 0 Hz tone lasting 10.9 ± 1.1 s.

Project CETI is an international initiative to understand the acoustic communication of sperm whales using advances in artificial intelligence. [1] [2] The project has an interdisciplinary scientific board including marine biologists, artificial intelligence researchers, roboticists, theoretical computer scientists, and linguists.
