Roger Payne
Roger Searle Payne (born January 29, 1935) is an American biologist and environmentalist famous for the 1967 discovery (with Scott McVay) of whale song among humpback whales. Payne later became an important figure in the worldwide campaign to end commercial whaling. History Payne was born in New York, New York, and received his BA degree at Harvard University and his Ph.D. at Cornell. He spent the early years of his career studying echolocation in bats (and how their food, moths, avoid them) and auditory localization in owls. Desiring to work with something more directly linked to conservation he later focused his research on whales where, together with researcher Scott McVay, in 1967 they discovered the complex sonic arrangements performed by the male humpback whales during the breeding season. These findings were published in the article ''Songs of humpback whales'' in 1971. Payne describes the whale songs as "exuberant, uninterrupted rivers of sound" with long repeated "th ...

Songs Of The Humpback Whale (album)
''Songs of the Humpback Whale'' is a 1970 album produced by bio-acoustician Roger Payne. It publicly demonstrated for the first time the elaborate whale vocalizations of humpback whales. Selling over 100,000 copies, it became the bestselling environmental album in history, and its sales benefited the Wildlife Conservation Society's Whale Fund, of which Payne was Scientific Director, and which sought to conserve whales through research and public education. By raising awareness of the intelligence and culture of whales, the album helped spawn a worldwide ”Save The Whales” movement, leading to the 1972 United Nations Conference on the Human Environment ten-year global moratorium on commercial whaling (observed by all but a few nations). Background Roger Payne had a background in bat and owl echolocation, but his interest in whale vocalizations came about by chance. In the late 1960s he heard on the radio that a dead whale had washed up on Revere Beach (near Tufts University wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York City
New York, often called New York City or NYC, is the List of United States cities by population, most populous city in the United States. With a 2020 population of 8,804,190 distributed over , New York City is also the List of United States cities by population density, most densely populated major city in the United States, and is more than twice as populous as second-place Los Angeles. New York City lies at the southern tip of New York (state), New York State, and constitutes the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the world by urban area, urban landmass. With over 20.1 million people in its metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, New York is one of the world's most populous Megacity, megacities, and over 58 million people live within of the city.

Sound Localization
Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or intensity difference) between the ears, and spectral information. These cues are also used by other animals, such as birds and reptiles, but there may be differences in usage, and there are also localization cues which are absent in the human auditory system, such as the effects of ear movements. Animals with the ability to localize sound have a clear evolutionary advantage. How sound reaches the brain Sound is the perceptual result of mechanical vibrations traveling through a medium such as air or water. Through the mechanisms of compression and rarefaction, sound waves travel through the air, bounce off the pinna and concha of the exte ...

National Geographic (magazine)
''National Geographic'' (formerly the ''National Geographic Magazine'', sometimes branded as NAT GEO) is a popular American monthly magazine published by National Geographic Partners. Known for its photojournalism, it is one of the most widely read magazines of all time. The magazine was founded in 1888 as a scholarly journal, nine months after the establishment of the society, but is now a popular magazine. In 1905, it began including pictures, a style for which it became well-known. Its first color photos appeared in the 1910s. During the Cold War, the magazine committed itself to present a balanced view of the physical and human geography of countries beyond the Iron Curtain. Later, the magazine became outspoken on environmental issues. Since 2019, controlling interest has been held by The Walt Disney Company. Topics of features generally concern geography, history, nature, science, and world culture. The magazine is well known for its distinctive appearance: a thick squa ...

Flexi Disc
The flexi disc (also known as a phonosheet, Sonosheet or Soundsheet, a trademark) is a phonograph record made of a thin, flexible vinyl sheet with a molded-in spiral stylus groove, and is designed to be playable on a normal phonograph turntable. Flexible records were commercially introduced as the Eva-tone Soundsheet in 1962. They were very popular among children and teenagers and mass-produced by the state publisher in the Soviet government. History Before the advent of the compact disc, flexi discs were sometimes used as a means to include sound with printed material such as magazines and music instruction books. A flexi disc could be moulded with speech or music and bound into the text with a perforated seam, at very little cost and without any requirement for a hard binding. One problem with using the thinner vinyl was that the stylus's weight, combined with the flexi disc's low mass, would sometimes cause the disc to stop spinning on the turntable and become held in place b ...
