Why then is it largely left off lists of the world's loudest animals?According to Wahlberg, "the way we hear sound is not only related to its intensity, but also its duration." Far back on the side of the head, and low down, near the angle of either whale's jaw, if you narrowly search, you will at last see a lashless eye, which you would fancy to be a young colt's eye; so out of all proportion is it to the magnitude of the head.Now, from this peculiar sideway position of the whale's eyes, it is plain that he can never see an object which is exactly ahead, no more than he can one exactly astern. It lasts only 100 microseconds, while blue whale calls last from 10 to 30 seconds.Whales are not the only contenders for the loudest animals. The ear has no external leaf whatever; and into the hole itself you can hardly insert a quill, so wondrously minute is it. Yes whales do have ears that are specially designed for being able to listen to sounds underwater.. While its calls are claimed to be louder than a jet engine at take-off, clocking in at an impressive 188 decibels (dB), the sperm whale is actually louder: its communicative clicks have been measured at 230 dB.Looked at side by side, the numbers seem pretty conclusive, but decibels, which measure sound pressure, are not the only way to measure loudness.In fact, loudness is subjective, dependent on how humans perceive it. But it is an impressive din nonetheless for a creature so small.However, when it comes to loudness relative to size, another tiny aquatic animal takes the title.This record raises another important point about loudness. In short, he is what the fishermen technically call a "grey-headed whale. The sound is amplified by their hollow abdomen. It is lodged a little behind the eye. Thunder And Lightning.Chapter 128 - The Pequod Meets The Rachel.Chapter 131 - The Pequod Meets The Delight. We engage our partners as we develop regulations and management plans that encourage recovery, foster healthy fisheries, reduce the risk of entanglements, create whale-safe shipping practices, and reduce ocean noise. "For instance, rather surprisingly, the largest Australian cicadas have yet to have to have their song amplitudes measured," says Popple.
So long as a man's eyes are open in the light, the act of seeing is involuntary; that is, he cannot then help mechanically seeing whatever objects are before him. ".So the sperm whale is still ahead. But far more terrible is it to behold, when fathoms down in the sea, you see some sulky whale, floating there suspended, with his prodigious jaw, some fifteen feet long, hanging straight down at right-angles with his body, for all the world like a ship's jib-boom. In a word, you would have two backs, so to speak; but, at the same time, also, two fronts (side fronts): for what is it that makes the front of a man--what, indeed, but his eyes?Moreover, while in most other animals that I can now think of, the eyes are so planted as imperceptibly to blend their visual power, so as to produce one picture and not two to the brain; the peculiar position of the whale's eyes, effectually divided as they are by many cubic feet of solid head, which towers between them like a great mountain separating two lakes in valleys; this, of course, must wholly separate the impressions which each independent organ imparts. The Sperm whale is known as the deepest diving marine mammal in the world.. Not at all.--Why then do you try to "enlarge" your mind? While the ear of the former has an external opening, that of the latter is entirely and evenly covered over with a membrane, so as to be quite imperceptible from without.Is it not curious, that so vast a being as the whale should see the world through so small an eye, and hear the thunder through an ear which is smaller than a hare's? But if his eyes were broad as the lens of Herschel's great telescope; and his ears capacious as the porches of cathedrals; would that make him any longer of sight, or sharper of hearing? "Blue whales call at 20 Hz and sperm whales at around 10 kHz," says Wahlberg. Commercial whaling from 1800 to the 1980s greatly decreased sperm whale population w… There are generally forty-two teeth in all; in old whales, much worn down, but undecayed; nor filled after our artificial fashion. Here, now, are two great whales, laying their heads together; let us join them, and lay together our own.Of the grand order of folio leviathans, the Sperm Whale and the Right Whale are by far the most noteworthy. This whale is not dead; he is only dispirited; out of sorts, perhaps; hypochondriac; and so supine, that the hinges of his jaw have relaxed, leaving him there in that ungainly sort of plight, a reproach to all his tribe, who must, no doubt, imprecate lock-jaws upon him.In most cases this lower jaw--being easily unhinged by a practised artist--is disengaged and hoisted on deck for the purpose of extracting the ivory teeth, and furnishing a supply of that hard white whalebone with which the fishermen fashion all sorts of curious articles, including canes, umbrella-stocks, and handles to riding-whips.With a long, weary hoist the jaw is dragged on board, as if it were an anchor; and when the proper time comes--some few days after the other work--Queequeg, Daggoo, and Tashtego, being all accomplished dentists, are set to drawing teeth.

Both are massive enough in all conscience; but there is a certain mathematical symmetry in the Sperm Whale's which the Right Whale's sadly lacks. The whale ear is acoustically isolated from the skull by air-filled sinus pockets, which allow for greater directional hearing underwater.
