“The Bomb Plot message” was a dispatch from Tokyo to its Consulate in Honolulu that the United States intercepted on September 24, 1941. This “strictly secret” message issued instructions to report gridded locations and detailed information on all ships in the waters of Pearl Harbor. The message was translated in Washington on October 9 by Colonel Rufus C. Bratton who found it significant as no previous Japanese intercepts requested or reported gridded positions of ships in the harbor. Bratton shared the message with his chief, General Miles, who interpreted the evidence through the confirmation bias lens and failed to analyze it as anything other than routine Japanese traffic regarding U.S. Naval movements. Still, Bratton routed the message to high levels of the War Department where it garnered very little
The Liberty Bell is a symbol of American independence and is located in Philadelphia, Pennsylvania. The government paid around 100 pounds for the bell (A&E Television Networks). It was once rung in the tower of the Pennsylvania State House, which is now called the Independence Hall. This bell was used to call the lawmakers to meeting and the people of the town to hear the reading of the news. Isaac Norris is the person that ordered for a bell in 1751, and on the first ring the bell cracked. Once it was cracked, John Pass and John Stow melted it down and casted a new one right in Philadelphia. (U.S. Department of the Interior) Both of their last names are on the bell after doing the new cast on the bell. (Liberty Bell Facts)
In Frankenstein and The Bride of Frankenstein, sound is used as an effect to scare people and create a “spooky” feeling. They used the sounds of a storm with rain and thunder, the sound of footsteps coming up from behind people, and other noises like creaky stairs, floors, and doors. This created that “haunted” or “spooky” feeling that would be used over and over again in horror films for decades. When they used sound effects, it was to emphasize that something was either happening or about to happen.
Loud noises a common cause of hearing. Constant exposure to loud noises such as noises made by drilling equipments and very loud music, causes the gradual damage of the hair cells in cochlea. Exposure to thunderous noise of explosions can cause sudden hearing loss.

...orthy (2012) completed a narrative review. This article was not classified as a systematic nor integrative, although the research was comprehensive. Edworthy (2012) completed a review including many of the traditional medical literature databases such as PubMed and Web of Knowledge. She additionally searched in the PsychINFO and human factor journals. Her strategy was to examine the available research specific to auditory alarm response time. Fifty eight articles were cited in this review. This article represented a comprehensive narrative by an expert in the specialty area. The author had twenty-five years experience as a researcher and designer in the area of audible alarms. Her findings suggested a significant improvement in response to alarms when greater emphasis is placed on the alarm design (Edworthy, 2012). She recommended standardization of alarms.

To begin with, the Invention that Alexander Graham Bell is most remembered for is the telephone. I will explain the idea, how it works, and the story behind it. First, the harmonic telephone was just an idea till about the year 1874 when Mr. Bell started work on the phone to send multiple telegraph messages at one time. This device would take a telegraph line to transfer the human voice from one place to another. For this job he hired a man named Thomas A. Watson, electrical designer. Second, the way this machine works is that the transmitter was in one room with metal strings attached to the device. Which looked like a cone connected to metal strings. Those strings would stretch out of the room to a different room. In the other room the receiver was there this looked like an 8 ounce cup of water. These two things were the transmitter and receiver of the first telephone from 1876. Thirdly, the story behind the telephone made it even more special that Mr. Bell actually made the telephone in Canada and was never an American citizen yet got the protection of invention by the United States of America. This story all started when Alexander was in his room working on the phone and his partner...
For Whom The Bell Tolls by Ernest Hemingway takes place during the Spanish Civil War, which devastated the nation of Spain from 1936 to 1939. The conflict started after an attempted coup d'état by a group of Spanish generals against the regime of the Second Spanish Republic, under the leadership of Manuel Azaña. The Nationalist coup was supported by the conservative Spanish Confederation of the Autonomous Right, Carlist monarchists, and the Fascist Falange. The events of the story center around Robert Jordan, an American volunteer for the Republican guerilla band. Jordan and the guerilla band attempt to defend Spain from the nationalist coup and preserve their way of life. However, the Republicans are unsuccessful because the Nationalists achieve victory, overthrow the government, and General Francisco Franco becomes dictator of Spain. The actions of people like Robert Jordan reveal that Spain was worth the overwhelming price to fight because the guerillas want to preserve and protect their ideals and way of life.

“The Bells,” a poem written by Edgar Allan Poe, conveys a cheerful tone through distinct sounds and repetition of words. A deeply onomatopoeic poem, “The Bells” progresses after every stanza. Primarily, the alliteration, assonance, and onomatopoeia in the poem produce a happy tone; but, towards the end of the poem, the sound devices help establish a gloomier tone. In each stanza, the bells are made of a different metal substance. In the first stanza, the bells are described as silver. In this case, the bells are pleasant, precious, and strong. Moreover, the bells portray the stages in life. The first stanza explains a man’s happy childhood. The golden bells in the second stanza are an example of a man’s love life through marriage. The brazen bells in the third stanza depict the terror of a human’s life through aging, and the iron bells in the fourth stanza show the mourning and death of a human. To fulfill the sense of excitement and happiness throughout the first stanza, Poe uses repeating words and consonants, long vowels, and imitation of sounds. The alliteration, assonance, and onomatopoeia all contribute to the joyful and merry tone of “The Bells.”
On March 10th, 1876, a revolutionary invention was created by Alexander Graham Bell. The telephone was invented to send vibrations from one receiver to another electrically (History.com ‘Speech Transmitted by Telephone’ accessed on March 11, 2014), and due to Alexander Graham Bell accidentally discovering that he could hear the sound of a ‘clock spring twanging’ (Marry Bellis, ‘The History of the Telephone’ accessed on March 11, 2014), that was possible. The invention of the telephone permitted new levels of communication, allowed families connect around the world, and improved military systems, but also served negative consequences, such as breached privacy. If two people wanted to have a conversation, they would have to write letters back and forth, but with the telephone they were able to pick up the receiver, dial the number, and be connected in a matter of minutes. Telephones enabled long-distance communication, which allowed families to converse despite their location. Military officials and soldiers were also able to stay in touch through field telephones as well as keep contact with the president. Although telephones were originally placed in general stores or other major city locations and homes/neighborhoods that were wired (Elon.edu ‘World Changes Due to the Telephone’ accessed on April 2, 2014), telephones became commonly used in homes in the early twentieth century when telephones began to connect internationally.
