Whale Vocalization
Whales use a variety of sounds for animal communication, communication and sensation. The mechanisms used to produce sound vary from one family of cetaceans to another. Marine mammals, including whales, dolphins, and porpoises, are much more dependent on sound than land mammals due to the limited effectiveness of other senses in water. Visual perception, Sight is less effective for marine mammals because of the way particulates in the ocean scatter light. Olfaction, Smell is also limited, as molecules diffuse more slowly in water than in air, which makes smelling less effective. However, the speed of sound is roughly four times greater in water than in the atmosphere at sea level. As sea mammals are so dependent on hearing to communicate and feed, environmentalists and cetology, cetologists are concerned that they are being harmed by the increased ambient noise in the world's oceans caused by ships, sonar and marine Reflection seismology, seismic surveys. The word "song" is use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humpback Whale
The humpback whale (''Megaptera novaeangliae'') is a species of baleen whale. It is a rorqual (a member of the family Balaenopteridae) and is the monotypic taxon, only species in the genus ''Megaptera''. Adults range in length from and weigh up to . The humpback has a distinctive body shape, with long pectoral fins and tubercles on its head. It is known for Cetacean surfacing behaviour, breaching and other distinctive surface behaviors, making it popular with whale watching, whale watchers. Males produce a complex Whale sound, song that typically lasts from 4 to 33 minutes. Found in oceans and list of seas, seas around the world, humpback whales typically animal migration, migrate between feeding areas towards the poles and breeding areas near the equator. They feed in Polar region, polar waters and migrate to tropics, tropical or subtropical waters to breed and give birth. Their diet consists mostly of krill and small fish, and they usually Bubble-net feeding, use bubbles to c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Rothenberg
David Rothenberg (born 1962) is a professor of philosophy and music at the New Jersey Institute of Technology, with a special interest in animal sounds as music. He is also a composer and jazz musician whose books and recordings reflect a longtime interest in understanding other species such as singing insects by making music with them. Life and work Rothenberg graduated from Harvard and took his PhD from Boston University. Looking back at his high school years in the 1970s, Rothenberg told Claudia Dreifus of ''The New York Times'', "I was influenced by saxophonist Paul Winter's ''Common Ground'' album, which had his own compositions with whale and bird sounds mixed in. That got me interested in using music to learn more about the natural world." As an undergraduate at Harvard, Rothenberg created his own major to combine music with communication. He traveled in Europe after graduation, playing jazz clarinet. Listening to the recorded song of a hermit thrush, he heard s ...

Paul Winter
Paul Winter (born August 31, 1939) is an American saxophonist, composer, and bandleader. He is a pioneer of world music and earth music, which interweaves the voices of the wild with instrumental voices from classical, jazz and world music. The music is often improvised and recorded in nature to reflect the qualities brought into play by the environment. Early life Winter was born in Altoona, Pennsylvania, United States. He studied piano and clarinet, then fell in love with saxophone in the fourth grade. He started the Little German Band with his schoolmates when he was twelve, then a Dixieland band, and a nine-piece dance band known as The Silver Liners. He became enthralled by big bands and bebop bands of the 1950s. After graduating from Altoona Area High School in 1957, he spent the summer on a tour of state fairs in the Midwest with the conductor and members of the Ringling Brothers Circus Band.

George Crumb
George Henry Crumb Jr. (24 October 1929 – 6 February 2022) was an American composer of avant-garde contemporary classical music. Early in his life he rejected the widespread modernist usage of serialism, developing a highly personal musical language which "range in mood from peaceful to nightmarish". Crumb's compositions are known for pushing the limits of technical prowess by way of frequent use of extended techniques. The unusual timbres he employs evoke a surrealist atmosphere which portray emotions of considerable intensity with vast and sometimes haunting soundscapes. His few large-scale works include '' Echoes of Time and the River'' (1967), which won the 1968 Pulitzer Prize for Music, and '' Star-Child'' (1977), which won the 2001 Grammy Award for Best Contemporary Classical Composition; however, his output consists of mostly music for chamber ensembles or solo instrumentalists. Among his best known compositions are '' Black Angels'' (1970), a striking commentary o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrophones
A hydrophone () is a microphone designed for underwater use, for recording or listening to underwater sound. Most hydrophones contains a piezoelectric transducer that generates an electric potential when subjected to a pressure change, such as a sound wave. A hydrophone can also detect airborne sounds but is insensitive of them because it is designed to match the acoustic impedance of water, a denser fluid than air. Sound travels 4.3 times faster in water than in air, and a sound wave in water exerts a pressure 60 times more than what is exerted by a wave of the same amplitude in air. Similarly, a standard microphone can be buried in the ground, or immersed in water if it is put in a waterproof container but will give poor performance because of the similarly-bad acoustic impedance match. History The first hydrophones consisted of a tube with a thin membrane covering the submerged end and the observer's ear of the equipment. The design of effective hydrophones must take into ...

Roger Payne
Roger Searle Payne (January 29, 1935 – June 10, 2023) was an American biologist and environmentalist famous for his 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. Early life Payne was born on January 29, 1935, in Manhattan, New York City, to Elizabeth (née Searle) and Edward Benedict Payne. His mother was a music teacher and his father an electrical engineer. Payne graduated from Horace Mann School in 1952. He later received his BA degree at Harvard University and his Ph.D. at Cornell University. Career Payne 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. He and fellow researcher Scott McVay in 1967 discovered the complex sonic arrangements performed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
