Whale vocalizations are the sounds made by whales to communicate. The word "song" is used in particular to describe the pattern of regular and predictable sounds made by some species of whales (notably the humpback and bowhead whales) in a way that is reminiscent of human singing. Humans produce sound by expelling air through the larynx.
Thunder is the sound caused by lightning. [1][2][3] Depending upon the distance from and nature of the lightning, it can range from a long, low rumble to a sudden, loud crack. The sudden increase in temperature and hence pressure caused by the lightning produces rapid expansion of the air in the path of a lightning bolt. [4]
Train. The Train is the name given to a sound recorded on March 5, 1997, on the Equatorial Pacific Ocean autonomous hydrophone array. The sound rises to a quasi-steady frequency. According to the NOAA, the origin of the sound is most likely generated by a very large iceberg grounded in the Ross Sea, near Cape Adare.
A crossword (or crossword puzzle) is a word game consisting of a grid of black and white squares, into which solvers enter words or phrases ("entries") crossing each other horizontally ("across") and vertically ("down") according to a set of clues.

The balafon (pronounced / ˈ b æ l ə f ɒ n /, or, by analogy with xylophone etc., / ˈ b æ l ə f oʊ n /) is a gourd-resonated xylophone, a type of struck idiophone. [1] It is closely associated with the neighbouring Mandé, Bwaba Bobo, Senoufo and Gur peoples of West Africa, [1] [2] particularly the Guinean branch of the Mandinka ethnic group, [3] but is now found across West Africa from ...
The Sun is said to be extremely noisy, but we can’t hear it since sound doesn’t travel through space. Scientists at the University of Sheffield decided to use vibrations within our star's ...
Shepard tone. A spectrogram of ascending Shepard tones on a linear frequency scale. A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the bass pitch of the tone moving upward or downward, it is referred to as the Shepard scale.
See media help. The vuvuzela / vuːvuːˈzɛlə / is a horn, with an inexpensive injection-moulded plastic shell about 65 centimetres (2 ft) long, which produces a loud monotone note, typically around B♭ 3 [2] (the first B♭ below middle C). [3] Some models are made in two parts to facilitate storage, and this design also allows pitch variation.
