Vuvuzela
The vuvuzela is a horn with an inexpensive injection-moulded plastic shell about long, which produces a loud monotone note typically around B♭ 3 (the first B♭ below middle C). Some models are made in two parts to facilitate storage, and this design also allows pitch variation. Many types of vuvuzela, made by several manufacturers, may produce various intensity and frequency outputs. The intensity of these outputs depends on the blowing technique and pressure exerted. The indoor noise level caused the U.S. NCAA to permanently ban them after the 7 February 1987 Division I Men's Ice Hockey game between the Brown Bears and the Rensselaer Polytechnic Institute Engineers. The noise was so extreme that Brown formally complained and "The RPI Rule" was universally adopted. The vuvuzela is commonly used at football matches in South Africa, and it has become a symbol of South African football as the stadiums are filled with its sound. The intensity of the sound caught the atte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brass Instrument
A brass instrument is a musical instrument that produces sound by Sympathetic resonance, sympathetic vibration of air in a tubular resonator in sympathy with the vibration of the player's lips. The term ''labrosone'', from Latin elements meaning "lip" and "sound", is also used for the group, since instruments employing this "lip reed" method of sound production can be made from other materials like wood or animal horn, particularly early or traditional instruments such as the cornett, alphorn or shofar. There are several factors involved in producing different Pitch of brass instruments, pitches on a brass instrument. Slide (wind instrument), Slides, Brass instrument valve, valves, Crook (music), crooks (though they are rarely used today), or Key (instrument), keys are used to change vibratory length of tubing, thus changing the available harmonic series (music), harmonic series, while the player's embouchure, lip tension and air flow serve to select the specific harmonic produ ...

Decibel
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a Power, root-power, and field quantities, power or root-power quantity on a logarithmic scale. Two signals whose level (logarithmic quantity), levels differ by one decibel have a power ratio of 101/10 (approximately ) or root-power ratio of 101/20 (approximately ). The strict original usage above only expresses a relative change. However, the word decibel has since also been used for expressing an Absolute scale, absolute value that is relative to some fixed reference value, in which case the dB symbol is often suffixed with letter codes that indicate the reference value. For example, for the reference value of 1 volt, a common suffix is "#Voltage, V" (e.g., "20 dBV"). As it originated from a need to express power ratios, two principal types of scaling of the decibel are used to provide consistency depending on whether the scaling refer ...

Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Kaizer Chiefs F
Kaiser ( ; ) is the title historically used by German and Austrian emperors. In German, the title in principle applies to rulers anywhere in the world above the rank of king (). In English, the word ''kaiser'' is mainly applied to the emperors of the unified German Empire (1871–1918) and the emperors of the Austrian Empire (1804–1918). During the First World War, anti-German sentiment was at its zenith; the term ''kaiser''—especially as applied to Wilhelm II, German Emperor—thus gained considerable negative connotations in English-speaking countries. Especially in Central Europe, between northern Italy and southern Poland, between western Austria and western Ukraine and in Bavaria, Emperor Franz Joseph I of Austria, Franz Joseph I is still associated with (the emperor) today. As a result of his long reign from 1848 to 1916 and the associated Golden Age before the First World War, this title often has still a very high historical respect in this geographical area. Etym ...

Bokoni
Bokoni (meaning 'land of the people from the north') was a pre-colonial, agro-pastoral society found in northwestern and southern parts of present-day Mpumalanga province, South Africa. Iconic to this area are stone-walled sites, found in a variety of shapes and forms. Bokoni sites also exhibit specialized farming and long-distance trading with other groups in surrounding regions. Bokoni saw occupation in varying forms between approximately 1500 and 1820 A.D. Etymology Bokone translates to "northern region", and with the class 2 prefix it takes the meaning "people from the north'. In spite of inaccuracies surrounding the term 'Koni' (having been used to describe an incorrect background as Nguni in a modern ethnolinguistic sense), it is still used in reference to the communities associated with Bokoni. For comparison, in the same way that Bokoni relates to the Koni, "Bopedi" refers to the area or society of the Pedi people. Description Settlement It is thought in recen ...

Sepedi Language
Sepedi, also known as Northern Sotho, is one of South Africa’s twelve official languages and belongs to the Bantu language family, specifically the Sotho-Tswana group. The language is spoken mainly in Limpopo Province, and to a lesser extent in Gauteng, Mpumalanga, and North West''.'' Sepedi refers to the ''dialect'' spoken by the Pedi people.

Nguni Languages
The Nguni languages are a group of Bantu languages spoken in southern Africa (mainly South Africa, Zimbabwe and Eswatini) by the Nguni people. Nguni languages include Xhosa, Tsonga, Ndebele, and Swati. The appellation "Nguni" derives from their ancestor called Mnguni type. ''Ngoni'' (see below) is an older, or a shifted, variant. It is sometimes argued that the use of ''Nguni'' as a generic label suggests a historical monolithic unity of the people in question, where in fact the situation may have been more complex. The linguistic use of the label (referring to a subgrouping of Bantu) is relatively stable. From an English editorial perspective, the articles "a" and "an" are both used with "Nguni", but "a Nguni" is more frequent and more correct especially if "Nguni" is pronounced as it is suggested (). Classification Within a subset of Southern Bantu, the label "Nguni" is used both genetically (in the linguistic sense) and typologically (quite apart from any histor ...

Winslow Homer
Winslow Homer (February 24, 1836 – September 29, 1910) was an American landscape painter and illustrator, best known for his marine subjects. He is considered one of the foremost painters of 19th-century America and a preeminent figure in American art in general. Largely self-taught, Homer began his career working as a commercial illustrator. He subsequently took up oil painting and produced major studio works characterized by the weight and density he exploited from the medium. He also worked extensively in watercolor, creating a fluid and prolific oeuvre, primarily chronicling his working vacations. Early life Homer was born in Boston, Massachusetts, on February 24, 1836, the second of three sons of Charles Savage Homer and Henrietta Maria Benson Homer, both from long lines of New Englanders. His mother was a gifted amateur watercolorist and Homer's first teacher. She and her son had a close relationship throughout their lives. Homer took on many of her traits, includi ...

Fenway Park
Fenway Park is a ballpark located in Boston, Massachusetts, less than one mile from Kenmore Square. Since 1912, it has been the home field of Major League Baseball's (MLB) Boston Red Sox. While the stadium was built in 1912, it was substantially rebuilt in 1934, and underwent major renovations and modifications in the 21st century. It is the List of current Major League Baseball stadiums, oldest active ballpark in MLB. Because of its age and constrained location in Boston's dense Fenway–Kenmore, Fenway–Kenmore neighborhood, the park has many quirky features, including "The Triangle", Pesky's Pole, and the Green Monster in left field. It is the fifth-smallest among MLB ballparks by seating capacity, second-smallest by total capacity, and one of nine that cannot accommodate at least 40,000 spectators. Fenway has hosted the World Series eleven times, with the Red Sox winning six of them and the Atlanta Braves, Boston Braves winning one. Besides baseball games, it has also bee ...
