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 ...
Every toothed whale except the sperm whale has two sets of phonic lips and is thus capable of making two sounds independently. [29] Once the air has passed the phonic lips it enters the vestibular sac. From there, the air may be recycled back into the lower part of the nasal complex, ready to be used for sound creation again, or passed out ...
Like other whales, the male fin whale has been observed to make long, loud, low-frequency sounds. [19] Most sounds are frequency-modulated (FM) down-swept infrasonic pulses from 16 to 40 hertz frequency (the range of sounds that most humans can hear falls between 20 hertz and 20 kilohertz).
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 ...
As early as 1965, marine biologist and bioacoustics researcher William N. Tavolga referred to the fact that sperm whales clicks had been often called "'carpenter' sounds." [1] A later naval technical report in 1980 notes that "sperm whale click trains are called "'carpenter fish' sounds by Navy sonar-men."
[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.
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 ...
