Edgar Villchur
Edgar Marion Villchur (28 May 1917 – 17 October 2011) was an American inventor, educator, and writer widely known for his 1954 invention of the acoustic suspension loudspeaker which revolutionized the field of high-fidelity equipment. A speaker Villchur developed, the AR-3, is exhibited at The Smithsonian Institution's Information Age Exhibit in Washington, DC. Villchur's speaker systems provided improved bass response while reducing the speaker's cabinet size. Acoustic Research, Inc. (AR), of which he was president from 1954 to 1967, manufactured high-fidelity loudspeakers, turntables, and other stereo components of his design, and demonstrated their quality through "live vs. recorded" concerts. The company's market share grew to 32 percent by 1966. After leaving AR, Villchur researched hearing aid technology, developing the multichannel compression hearing aid, which became the industry standard for hearing aids. Background Villchur received his bachelor's and master ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Consumer Reports
Consumer Reports (CR), formerly Consumers Union (CU), is an American nonprofit consumer organization dedicated to independent product testing, investigative journalism, consumer-oriented research, public education, and consumer advocacy. Founded in 1936, CR was created to serve as a source of information that consumers could use to help assess the safety and performance of products. Since that time, CR has continued its testing and analysis of products and services, and attempted to advocate for the consumer in legislative and rule-making areas. Among the reforms in which CR played a role were the advent of seat belt laws, exposure of the dangers of cigarettes, and more recently, the enhancement of consumer finance protection and the increase of consumer access to quality health care. The organization has also expanded its reach to a suite of digital platforms. Consumer Reports Advocacy frequently supports left-wing environmental causes, including heightened regulations on auto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Consumers Union
A consumer is a person or a group who intends to order, or uses purchased goods, products, or services primarily for personal, social, family, household and similar needs, who is not directly related to entrepreneurial or business activities. The term most commonly refers to a person who purchases goods and services for personal use. Consumer rights “Consumers, by definition, include us all," said President John F. Kennedy, offering his definition to the United States Congress on March 15, 1962. This speech became the basis for the creation of World Consumer Rights Day, now celebrated on March 15. In his speech : John Fitzgerald Kennedy outlined the integral responsibility to consumers from their respective governments to help exercise consumers' rights, including: *The right to safety: To be protected against the marketing of goods that are hazardous to health or life. *The right to be informed: To be protected against fraudulent, deceitful, or grossly misleading informatio ...

FM Radio
FM broadcasting is a method of radio broadcasting using frequency modulation (FM). Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to provide high fidelity sound over broadcast radio. FM broadcasting is capable of higher fidelity—that is, more accurate reproduction of the original program sound—than other broadcasting technologies, such as AM broadcasting. It is also less susceptible to common forms of interference, reducing static and popping sounds often heard on AM. Therefore, FM is used for most broadcasts of music or general audio (in the audio spectrum). FM radio stations use the very high frequency range of radio frequencies. Broadcast bands Throughout the world, the FM broadcast band falls within the VHF part of the radio spectrum. Usually 87.5 to 108.0 MHz is used, or some portion thereof, with few exceptions: * In the former Soviet republics, and some former Eastern Bloc countries, the older 65.8–74 MHz band ...

Edwin Howard Armstrong
Edwin Howard Armstrong (December 18, 1890 – February 1, 1954) was an American electrical engineer and inventor, who developed FM (frequency modulation) radio and the superheterodyne receiver system. He held 42 patents and received numerous awards, including the first Medal of Honor awarded by the Institute of Radio Engineers (now IEEE), the French Legion of Honor, the 1941 Franklin Medal and the 1942 Edison Medal. He was inducted into the National Inventors Hall of Fame and included in the International Telecommunication Union's roster of great inventors.

Royalties
A royalty payment is a payment made by one party to another that owns a particular asset, for the right to ongoing use of that asset. Royalties are typically agreed upon as a percentage of gross or net revenues derived from the use of an asset or a fixed price per unit sold of an item of such, but there are also other modes and metrics of compensation.Guidelines for Evaluation of Transfer of Technology Agreements, United Nations, New York, 1979 A royalty interest is the right to collect a stream of future royalty payments. A license agreement defines the terms under which a resource or property are licensed by one party to another, either without restriction or subject to a limitation on term, business or geographic territory, type of product, etc. License agreements can be regulated, particularly where a government is the resource owner, or they can be private contracts that follow a general structure. However, certain types of franchise agreements have comparable provisions. N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KLH (company)
KLH Audio is an American audio electronics company based in Noblesville, Indiana. Originally founded in 1957 as KLH Research and Development Corporation in Cambridge, Massachusetts, the company takes its name from the initials of its founders: Henry Kloss, Malcolm S. Low, and Josef Anton Hofmann. History The original aim of the company was to design and produce loudspeakers in speaker enclosures. KLH had sales of $17 million, employed over 500 people and sold over 30,000 speakers a year before it was sold to Singer Corporation in 1964.

Sound Reproduction
Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects. The two main classes of sound recording technology are analog recording and digital recording. Sound recording is the transcription of invisible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves. Acoustic analog recording is achieved by a microphone diaphragm that senses changes in atmospheric pressure caused by acoustic sound waves and records them as a mechanical representation of the sound waves on a medium such as a phonograph record (in which a stylus cuts grooves on a record). In magnetic tape recording, the sound waves vibrate the microphone diaphragm and are converted into a varying electric current, which is then converted to a v ...

Henry Kloss
Henry Kloss (February 21, 1929 – January 31, 2002) was a prominent American audio engineer and entrepreneur who helped advance high fidelity loudspeaker and radio receiver technology beginning in the 1950s. Kloss (pronounced with a long o, like "close") was an undergraduate student in physics at the Massachusetts Institute of Technology (class of 1953), but never received a degree. He was responsible for a number of innovations, including, in part, the acoustic suspension loudspeaker and the high fidelity cassette deck. In 2000, Kloss was one of the first inductees into the Consumer Electronics Association's Hall of Fame. He earned an Emmy Award for his development of a projection television system, the Advent VideoBeam 1000. Career During the course of his half-century career, Kloss founded or co-founded several significant audio and video equipment manufacturing companies, most of which were located in Cambridge, Massachusetts, at least during the period he was directly asso ...
