Learn About the History of the Microphone

A microphone is a device for converting acoustic power into electric power with essentially similar wave characteristics. These devices convert sound waves into electrical voltages that are subsequently converted back into sound waves and amplified through speakers. Today, microphones are most often associated with the music and entertainment industries, but the devices date back as far as the 1600s when scientists began seeking out ways in which they could amplify sound. The 1600s 1665: While the word â€Å"microphone† wasn’t used until the 19th century, English physicist and inventor Robert Hooke is credited with developing an acoustic cup and string style phone and is considered a pioneer in the field of transmitting sound across distances. The 1800s 1827: Sir Charles Wheatstone was the first person to coin the phrase microphone. A renowned English physicist and inventor, Wheatstone is best known for inventing the telegraph. His interests were varied, and he devoted some of his time the study of acoustics during the 1820s. Wheatstone was among the first scientists to formally recognize that sound was transmitted by waves through mediums. This knowledge led him to explore ways of transmitting sounds from one place to another, even over long distances. He worked on a device that could amplify weak sounds, which he called a microphone. 1876: Emile Berliner invented what many consider the first modern microphone while working with famed inventor Thomas Edison. Berliner, a German-born American, was best known for his invention of the Gramophone and the gramophone record, which he patented in 1887. After seeing a Bell Company demonstration at the U.S. Centennial Exposition, Berliner was inspired to find ways to improve the newly invented telephone. The Bell Telephone Companys management was impressed with the device he came up with, a telephone voice transmitter, and bought Berliners microphone patent for $50,000. (Berliners original patent was overturned and later credited to Edison.) 1878: Just a couple years after Berliner and Edison created their microphone, David Edward Hughes, a British-American inventor/music professor, developed the first carbon microphone. Hughess microphone was the early prototype for the various carbon microphones still in use today. The 20th Century 1915: The development of the vacuum tube ampliï ¬ er helped improve the volume output for devices, including the microphone. 1916: The condenser microphone, often referred to as a capacitor or an electrostatic microphone, was patented by inventor E.C. Wente while working at Bell Laboratories. Wente had been tasked with improving the audio quality for telephones but his innovations also enhanced the microphone. 1920s: As broadcast radio became one of the premier sources for news and entertainment around the world, the demand for improved microphone technology grew. In response, the RCA Company developed the first ribbon microphone, the PB-31/PB-17, for radio broadcasting. 1928: In Germany, Georg Neumann and Co. was founded and rose to fame for its microphones. Georg Neumann designed the first commercial condenser microphone, nicknamed â€Å"the bottle† because of its shape. 1931: Western Electric marketed its 618 Electrodynamic Transmitter, the ï ¬ rst dynamic microphone. 1957: Raymond A. Litke, an electrical engineer with Educational Media Resources and San Jose State College  invented and filed a patent for the first wireless microphone. It was designed for multimedia applications including television,  radio, and higher education. 1959: The Unidyne III microphone was the first uni-directional device designed to collect sound from the top of the microphone, rather than the side. This set a new level of design for microphones in the future. 1964: Bell Laboratories researchers James West and Gerhard Sessler received patent no. 3,118,022 for the electroacoustic transducer, an electret microphone. The electret microphone offered greater reliability and higher precision at a lower cost and with a smaller size. It revolutionized the microphone industry, with almost one billion units manufactured each year. 1970s: Both dynamic and condenser mics were further enhanced, allowing for a lower sound level sensitivity and a clearer sound recording. A number of miniature mics were also developed during this decade. 1983: Sennheiser developed the first clip-on microphones: one that was a directional mic (MK# 40) and one that was designed for the studio (MKE 2). These microphones are still popular today. 1990s: Neumann introduced the KMS 105, a condenser model designed for live performances, setting a new standard for quality. The 21st Century 2000s: MEMS (Microelectromechanical systems) microphones begin making inroads in portable devices including cell phones, headsets, and laptops. The trend for miniature mics continues with applications such as wearable devices, smart home, and automobile technology, 2010: The Eigenmike was released, a microphone that is composed of several high-quality microphones arranged on the surface of a solid sphere, allowing the sound to be captured from a variety of directions. This allowed for greater control when editing and rendering sound.

While a majority of adults continually struggle to cope with the occurrence Of death, this Story tells a tale of children who have practically become accustomed to it. Beauty provides a distinct look at this urban school setting through her inside view of student emotions, evidence of pain within the kids, and the feelings that she evokes from the audience despite her straightforward tone. (simple) While first reading about Ms. We will write a custom essay sample on Survival Skills In South Central LA or any similar topic only for you Order Now Beauty and her inside story into this previously uncharted territory, sensed as though she was a woman who possessed a very intimate bond with the students. In the story, when describing what occurred on days when the students mourned someone who was killed, Ms. Beauty notes that â€Å"boys lingered over handshakes and looked into my eyes solemnly. Girls threw their arms around me and wordlessly moved away. No one said enough. † (Beauty; par. 5). A majority of her descriptions of students and events, as well as her diction, seem somewhat heartfelt yet a bit plainly stated on the surface; however, the cultural distance between Ms. Beauty and the students seemingly increases the more we observe how she interacts with them. When Ms. Beauty discusses how the kids hugged her, the description actually makes her seem somewhat aloof. The way that the author words the sentence makes it seem as though the children approach her with emotions and she is simply present, receiving the actions. As a teacher, Beauty never necessarily makes a huge effort to help the student’s cope with these devastating loses, except in the case of Dander where Ms. Beauty does display some emotional involvement. On the day of this peculiar interaction between student and teacher, Beauty â€Å"was not prepared for the sight one day f Dander, standing alone behind the stairwell. (Beauty; par. 6). However, even in this case we see her as an outsider looking in: when a counselor arrives after a failed attempt to comfort her student, Ms. Beauty â€Å"watched them go with a mixture of relief and dread. Out of [her] hands. † She obviously had worthy intentions to comfort Dander, but the situation seemed to be bigger than anything she could resolve. Ms. Beats trustworthiness becomes another important factor to focus our attention on and her illustration of events keys us into the devastation that sakes place in South Central Los Angels. The story itself does not appear to include any influence of bias, but the author narrates from a personal point of view and therefore the article contains her opinions and viewpoints on the matter. Ms. Beauty gives credible information because she witnessed all of these hardships and events first-hand; she offers highly trust;rotor information in comparison to, for example, an internet news columnist who would write about different schools in Los Angels. When narrating, she delivers a subjective point of view that would not be attainable from an outside source. The tone throughout the article delivers a sense of authority that is unmatched to anything Vive ever read before, somehow conveying emotion in such a nondescript manner. While describing the tale of events, Beauty utilizes fairly straight forward language. When recounting Dander’s story of false accusation, she gives evidence to the type of misfortune that falls upon the shoulders of young teens in this area. The story of Dander evokes both logic and sympathy because no child should have to suffer this type of harassment and blame, especially not in Dander’s case because he ad such good intentions of standing up for his sister. Pathos lingers throughout this recap of Dander’s accusations When discussing the accusations, the Beauty says that Dander â€Å"was taken into custody, where he was told they already had evidence that he’d killed the boy and were just looking for a confession. The smartest thing he could do, they told him, was to confess, so they could get his sentence down to a few years. If he refused, he would get life. † (Beauty; par. 16). This section of the story really resonated with me, and cannot imagine a person falsely accusing me of murder or coaxed into making reparations for a crime of which did not take part in. Although it appears that Beauty lacks the same cultural background as the students, believe that she could have written her story with more conviction, urging readers to reach out to the hopeless children. Through researching, I found out about multiple organizations and charities that help motivate inner-city kids to graduate high school. When Beauty talked about her â€Å"heavy- footed student who looked too old for ninth grad’ (Beauty; par. 3), it made me realize that what some of these students needed was a ray of hope in heir violence-filled surroundings. One charity called the I Have A Dream Foundation pledges college education funding for kids who graduate high school, and this would be a great thing for Beauty to have introduced into the school. Focusing their efforts into schoolwork and attempting to make something out of their lives might be just the spark that South Central Los Angels would need to eliminate teen violence. Beats emotional involvement with her students is never quite enough; her aloofness, insensitivity, and difference in cultural upbringing make it difficult for her to innocent on a deep level with her students.
