Essay on how headphones changed the world

A very popular consumer item was the phonograph. It was first invented in 1877 but it was so expensive it took a while for the homes in america to get ahold of it , by the time of the 1920’s 7 million homes had their hands on one but they were still pretty expensive. The phonograph was a music recorder and to the people of america it was important because that's where most of their music came from either that other radio. It was referred to by many names like “talking machine” or “music machines” or its proper word “phonograph”. The most popular phonograph was called the “victor victrola”. Its inventors were Thomas Edison, Emile Berliner,Eldridge R. Johnson. The newer version of the phonograph that was produced in the 1920’s didn’t have

The history of music players dates back to November 21, 1877 when Thomas Alva Edison invented a device for recording sounds and then playing it back called the Gramophone. It was patented on February 19, 1878. The Gramophone looked like a cylinder that was smaller at one end and bigger at the other. Even today, at the annual Grammy Awards the awards that are given out are miniature versions of Edison’s invention.

Heffernan also illustrates how headphones work, stating, “when an audio current passes through the device’s voice coil, it creates an alternating magnetic field that moves a stiff, light diaphragm” (Heffernan, 2011). Describing the history of headphones and how the technology works portrays Heffernan as a reasonable author with a deep understanding of her subject matter, which earns the trust and respect of the audience.

Revealed Object and Speaker Credibility: Headphones are a pair of listening devices with speakers that are most commonly used to listen to music. The reason why this invention exists is because it helps you block out any distractions/noise from you and it prevents others from hearing what you hear.

The Navy caught wind of Baldwin’s invention, and headphones became commonplace for military workers and soldiers. Following World War II, headphones were designed for music consumption, which later led to the Walkman, the formation of Sony, and the headphones of modern times (Heffernan, 2011). Heffernan also provides an explanation of how headphones work, stating “when an audio current passes through the device’s voice coil, it creates an alternating magnetic field that moves a stiff, light diaphragm” (Heffernan, 2011). Describing the history of headphones and how the technology works portrays Heffernan as a credible author with a deep understanding of her subject matter, which earns the trust and respect of the audience.

Repeatedly, Heffernan mentions the hearing loss, and even states that young people are in danger of “. . . not having hummingbird attention spans, but going deaf.” By this, she is implying that the younger generations, which are typically thought of to have hyperactivity in the brain, may actually be going deaf. Seeing as how the audience of the article is young adults, it is apparent that the author is trying to scare them away from using headphones. By scaring the audience, she is further persuading them to think negatively of

“In 1913, Edwin Armstrong invented a special circuit that made long-range radio transmission of voice and music practical” (American). This technological advancement made it convenient to use the radio as means of delivering the news. Whether you lived in a rural countryside or in a packed city, you were able to get the news. Able to broadcast weather reports, sports news, and entertainment to thousands of Americans, the radio proved to be an invaluable resource.

We all want to be more productive because an increase in productivity leads to better grades. Now who doesn’t want better grades? According to the New York Times, many people use music to make a repetitive job more interesting or energetic. Some of the more melodious music out there can help release much higher amounts of dopamine which is a neurotransmitter that helps control the brain's reward and pleasure centers. By rewarding the mind we allow our mind to be happy which increases our focus and keeps us in the present moment. Business Insider tells us which songs help us the most. Many different songs have the power of benefitting us such as songs we enjoy and even music without lyrics. Songs that we enjoy make us feel better and like mentioned before, when we feel good we have more of a tendency to finish our work more efficiently. Music without any lyrics help us because the absence of words is less distracting. According to a Cambridge study, “speech distracts about 48% of office workers”. So next time you get off track or distracted, try listening to some music.

In his life Alexander Graham Bell invented a number of wide ranging inventions. Starting from a labor saving de-husker in his youth to the famous telephone to the predecessor of radio and fiber optic communications--the photophone and also a metal detector. His impact on science is permanently honored by naming the unit of sound intensity the bel (more commonly used as a decibel.) Everyone’s life is still affected strongly by the giant leap that Mr. Bell took when he decided to help deaf students

Headphones are a necessity for many people in today’s society. Headphones allow a person to listen to music without disturbing others; therefore people are listening to music all day while they eat, sleep, or work. In Derek Thompson’s essay, “How Headphones Changed the World”, Thompson addresses the problem of why workers use headphones even if studies have shown that it interferes with their productivity levels. Thompson effectively uses precise language and organizes his essay in a way that shows a breakdown of his thoughts on this topic. These two elements make the essay easy to understand, which enhances the audience’s reading experience.

Thomas Edison was the first to record sound while he was experimenting with his new telegraphing device ("Earliest Recordings Ever Made."). He did this by accidently running an indented tin foil under the telegraph's stylus ("Earliest Recordings Ever Made."). By the end of the year, he had successfully

     Back in Boston, Bell and Watson continued to work on the harmonic telegraph, but still with the telephone in mind. By accident on a June day in 1875, an intermittent transmitter produced a steady current and transmitted sound, when Watson tightened or loosened a particular screw it produced a sound that would vary in pitch. Bell had proof of his 1874 idea; he quickly

Music elicits an emotional and cognitive response in all who listen to it. It is powerful at the individual level because “it can induce multiple responses – physiological, movement, mood, emotional, cognitive, and behavioral” (Francis, 2008,
