INTRODUCTION
Throughout the history of civilizations man tried to establish his own way to express himself and represent his ideas to others. These ways, which are defined as languages, supported the ability to communicate, providing one of the most essential instincts needed by mankind.
For not over than few tens of meters, man’s sheer voice formed the first and simplest humanist wireless communication scheme, where the frequencies produced from the man's throat vibrates the surrounding air molecules and spread to reach the receiver's ear.
Man discovered that converting his throat vibrations, and hence his out-coming speech, into a corresponding electrical form could serve in carrying his voice on a conductor and transferring it for a distance determined by the conductor's length. The construction of the conducting mesh that joins the scattered geographical parts of the world formed what is known by the wired communication, which is still effective up to the moment, and in fact constitutes a very important scheme of communication.

Wireless is a methodical account of the early development of wireless telegraphy and the inventors who made it possible. Sungook Hong examines several early significant inventions, including Hertzian waves and optics, the galvanometer, transatlantic signaling, Marconi's secret-box, Fleming's air-blast key and double transformation system, Lodge's syntonic transmitter and receiver, the Edison effect, the thermionic valve, and the audion and continuous wave. Wireless fills the gap created by Hugh Aitken, who described at length the early development of wireless communication, but who did not attempt "to probe the substance and context of scientific and engineering practice in the early years of wireless" (p. x). Sungook Hong seeks to fill this gap by offering an exhaustive analysis of the theoretical and experimental engineering and scientific practices of the early days of wireless; by examining the borderland between science and technology; depicting the transformation of scientific effects into technological artifacts; and showing how the race for scientific and engineering accomplishment fuels the politic of the corporate institution. While the author succeeds in fulfilling these goals, the thesis, it seems, is to affirm Guglielmo Marconi's place in history as the father of wireless telegraphy.
Language is our power and expression is our freedom. Through a puff of air, we are able to communicate and influence the environments that surround us. Over the course of time humans have evolved, but by the means of language, humans have matured into humanity. The possibility of thought and emotions such as empathy show the ability to think with complexity. A crucial element that helps Suzanne K. Langer’s illustrate the essence of humanity throughout her essay “Language and Thought.” Langer thoroughly depicts what sets humans apart from the rest of the animal kingdom by explicitly stating “The line between man and beast […] is the language line” (120). Consequently, this implies that if a person is declined the freedom of language they are hardly considered human. Many people around the globe have had their voices silenced due to corrupt governments and the oppression of their culture. These individuals are subjected to the devastating effects of the loss of language, which in turn, translates to the loss of power. Language is our foundation for hopes and opportunity, for with out it a person is shell of possibility that is subjected to a passive existence.
“And in her ears the little Seashells, the thimble radios tamped tight, and an electronic ocean of sound, of music and talk and music and talk coming in, coming in on the shore of her unsleeping mind.” (Bradbury 76)
Humans have been using written language to communicate ideas with one another since as early as 3200 BCE in Mesopotamia. Since then, every great civilization has had a written language, each with its own unique characteristics. However, it was the writin...
The most important thing when interacting with other human beings is being able to communicate one another. People’s first mechanical way of communicating was with the invention of the telegraph, which was at first run by gas. It wasn’t until 1836, when Samuel F.B Morse, Alfred Vail, and Joseph Henry invented Morse code that our civilization had would be able to electronically communicate. Soon after, the first telephone was invented by Alexander Graham Bell which allowed people to vocally converse electronically from miles away. The invention of the telephone was then modified and eventually converted into a mobile cellular phone by Martin Cooper in...
Amplifying a person’s voice is a sufficient way of transmitting effective communication from a source to a receiver. Since the development of the carbon microphone, the progression of voice clarity via broadcasting systems has become much more efficient. The carbon microphone is also often referred to as the button microphone or carbon transmitter (“History of Microphones”). Although this specific microphone was not primarily the first voice enhancer ever created, it was ultimately one of the most significant. The carbon microphone was said to have been created between 1876 and 1877. Who exactly came up with this intricate invention is relatively undefined; some sources give all credit to a musically and intellectually talented collegiate professor and inventor named David Edward Hughes (Worrall 3). Others deem credit to a historically well-known inventor by the name of Thomas Alva Edison (Wills). Nonetheless, further sources acknowledge Emile Berliner for this patent of “one of the first ever created and by far the most usable” devices of all time (Shechmeister). Berliner is said to have invented this button microphone sometime in 1876. Later, his patent was refused by the Supreme Court, so the credit was sold to Thomas Edison (Shechmeister). As it turns out in many sources, Hughes actually created the first carbon transmitter microphone, but refused to patent it. Instead, seeing as how he was already a well-known, successful inventor, Hughes simply “reported his invention to the Royal Society in London on 8 May, and made it and its details available to the general public on 9 June” (Worrall). Since the designs of this invention we...
The origin and history of simultaneous communication are one of the most interesting phenomenons in the world of communication. This based on the fact that simultaneous communication essentially began as a channel of directing someone to something without the use of a particular language. In this, simultaneous language became widely in the any communication process that entailed more than two languages (Gaiba, 1998). It is realized that modern simultaneous interpretation utilizes sophisticated sound equipment for the enhancement of communication, proving simultaneous interpretations historical antecedents. Simultaneous co...

In 1877 Thomas A. Edison invented a machine called the phonograph, the name coming from two greek words, “phonē” meaning sound and “graphē” meaning write. This machine had the power to record and playback any sound. was caused from the work of the telephone and telegraph, and was originally made as an accessory so the speaker can say something once without have to repeat anything. This led to the first recorded human voice, Edison reciting “Mary had a little lamb”.
Language is a part of our everyday lives, and we can describe the meaning of language in many ways. As suggested in Gee and Hayes (2011, p.6 ) people can view language as something in our minds or something existing in our world in the form of speech, audio recordings, and writings or we can view language as a way of communicating with a group of people. Language can be used to express our emotions, make sense of our mental and abstract thoughts and assists us in communicating with others around us. Language is of vital importance for children to enable them to succeed in school and everyday life. Everyone uses both oral and written language. Language developed as a common ability amongst human beings with the change
Cell phones have immensely changed the way people communicate today. A cell phone can be all a person need for interaction. From a cell phone, a person can make calls, send text messages, emails, and send and also receive directions, buy things online, do online banking, listen to music and much more. Since someone can do everything with one device, there is no longer a need to go around with multiple devices about. Greek hydraulic semaphore systems were used as early as the 4th century. The hydraulic semaphores, which functioned with water filled containers and visual signals, functioned as optical telegraphs. However, they could only apply a very limited range of pre-determined messages, and as with all such visual telegraphs could only be deployed during good visibility conditions. Experiments on communication using electricity was carried out in 1729 but was not successful. The experiment was proposed by William Fothergill Cooke. In 1837, William invented a practical electric telegraph which entered commercial use in 1838 (J. B. Calvert, May 2004). The first telephone was invented in 1878 by Alexander Graham Bell. He experimented with a ‘phonautograph’, it is a machine shaped like a pen that can draw shapes of sound waves on smoked glass by tracing vibrations.
Despite the short amount of time since the introduction of the smartphone, the rapid development of the software and technology has had a tremendous effect on the everyday life of society today. The concept of communicating through a telephone was developed in the 1870s. Devices to transmit speech electrically were designed by Elisha Gray and Alexander Graham Bell, but Bell's design was patented first. On March 10, 1876, Alexander Graham Bell achieved one of his greatest successes in the making of the telephone. This brought upon a major change in communication and gave leeway to the improvement of the telephone in the days to come (Bellis, 2013b).

Headphone is the “electro-acoustic transducer for converting electric signals into sounds.” There are electronic devices shown in fig.1 and fig.2 that have similar function as headphone. However, it is not reasonable to call them headphones in modern society. In order to distinguish the headphone in this paper from other similar electronic devices, the headphone refers to the one that is held over the ear.
