It's Raining Men: The Physics Of How Sound Works

473 Words2 Pages

Intro:
Speakers, the magical electronics that let you enjoy your favorite music. Such as “It’s Raining Men”. Without speakers, you won’t be able to enjoy your video games, your music, or talk to your friends through the web. How do these magical equipments actually work? It might surprise you how simple the mechanics of a speaker is. Curious yet? I will teach you about these 2 main topics, how sound works, and how speakers work.
Speakers create sound waves, but what is sound? Inside the ear, there is a thin cone-shaped membrane called the eardrum (encyclopedia britannica n.d.) When the eardrum vibrates, your brain translates it to a sound (Harris, Tom 2001). The most common vibration is rapid changes in air pressure. Sound is created when an object vibrates in the air. The air particles around the object moves, and it creates a chain reaction where the object vibrates the air around it, and the air particles around the air particles vibrate, and so on (Harris, Tom. 2001). …show more content…

This creates a drop in pressure that makes air particles move in. This creates a irregular pressure in the air called rarefaction, but air particles move in to regulate the pressure. (Harris, Tom. 2001). Sound varies because of sound-wave frequency and air-pressure level. Sound-wave frequency is simply the speed of the fluctuation of air-pressure. The faster fluctuation, the higher pitch. Air-pressure is the sound’s amplitude which determines the volume of the sound. The greater amplitude makes the eardrum vibrate more, so we translate the vibration as a higher volume (Harris, Tom.

Lead them to point out that sound is made when there is a vibration. 3 Explain that the frequency of a sound is a measure of the number of vibrations or waves per second. 4 Explain that a sound with a high frequency will make a high-pitched sound, and one with a low frequency will make a low-pitched sound. 5 Explain that pitch is a measure of how

In the short story, “A sound of Thunder”, Ray Bradbury used figurative language to make a bigger impact on the story. When Eckels goes into the office he sees and hears, “... A sound like a gigantic bonfire burning all of Time, all the years and all the parchment calendars- all the hours piled high and set aflame.” The author, Ray Bradbury, wanted his audience to have a specific image set in the audience’s head. By using a simile he help the reader imagine how Eckle’s is going to get to the past.

When the glottis opens, the air explodes though the vocal folds, and that is the beginning of the first sound wave. To determine the loudness of the sound, it depends on the strength that you push through the larynx (Deirdre Michael,

The Awakening by Kate Chopin ends with the protagonist reliving old memories and eventually entering the ocean to drown herself. However, this ending does not feel like an ending for this character, instead it feels like a new beginning of awakening. This effect happens through the use of indicative diction, symbolic imagery, and alluring sound. This ending is seen as a new beginning or awakening for the protagonist through indicative diction. The protagonist claims that her children were like “antagonists,” plotting against her and put her in “soul’s slavery.”

“The Sound of Thunder” takes place in modern america. The protagonist, Eckels goes to a safari tour to take him to a safari in the past, to kill a tyrannosaurus rex. The safari company is very cautious about not changing the past. Eckels accidentally walks off the path made by the safari; his tour guide is furious with him. They later figure out that Eckels accidentally stepped on, and killed a butterfly; this changed the future for the worse.

As curious creatures, we are always determined to fulfill our fascination. This inner drive pushes us to disregard boundaries, allowing us to make discoveries. However, sometimes we push the limitations and get entangled with things we shouldn’t be. In the short story, A Sound of Thunder by Ray Bradbury, we are introduced to the character, Eckles, who is offered an opportunity to travel back in time. However, there is a rule he must obey, he must remain on the path to prevent the disruption of natural order.

There are many theories that explain what causes future events to happen. Is it destiny? Is it coincidence? Or is it the so-called “butterfly effect”? A proposition to end this debate is explained in the short story “A Sound of Thunder'' by the author Ray Bradbury.

Trinity Moore Mrs. Humphrey AP English 1/31/18 Short Story Anthology Assessment The short story novel A Sound of Thunder, written by Ray Bradbury, is filled with stories about adventure, space, loneliness, and more. What I interpreted from the book was that Bradbury used these stories to explain that humans have or will begin to isolate themselves from each other and earth itself. Beginning with the first story, “The Fog Horn,” This story is one of the most bitter stories in the entire book. Bradbury uses the words lonely, cry, deep, and alone many times throughout the story to make sure the reader understands that he wants the tone of this to be depressing.

Sound affects how the viewer perceives the reality created in a film. There are many tactics the sound designer can implement for the director to completely change how the visuals of a scene are interpreted or to enhance the interpretation that already exists due to visuals alone. The sound editor and sound designers for films use tools such as dialogue, loudness, pitch, narration, music, and silence to influence the perception of the audience. Even in the silent film era, musical accompaniment played an integral part of the mood created by the movie. Sounds are integral to establishing the audience’s perception of a film’s world.

The speed of sound is the distance travelled per unit time by a sound wave. The speed of sound is 331 m/s. The second concept that I used was the concept of wavelength. A wavelength is the distance between two points that are next to each other and are the same points in a wave. To find the wavelength one has to use the formula λ

The mechanical vibrations transmitted through a medium; solid, liquid or a gas generates a sound wave. The sound is an energy, which deflects the particles of a medium in the same direction, and itself travel as a longitudinal waveform with areas of compression and rarefactions. The image generated by ultrasound is essentially based on similar principle by means of a machine, which includes an ultrasound transducer and a screen. The transducer contains a piezoelectric crystal made up of lead zirconite, which generates an ultrasound beam on applying an electrical current to the transducer. These signals travel through a medium in the body and after striking with various tissues, return back to the transducer.

The purpose of this lab was to observe the phenomenon of resonance in an open ended cylindrical tube and use resonance to determine the velocity of sound in air at regular temperatures. A hypothesis for this lab was that if the frequency of the tuning fork increased, then the length of the tube to achieve resonance will increase because of the high amplitude of the vibration. The resonance of the open-closed tube was found through these steps. First, the tube was filled with water with an inner tube inside the outer tube. The water temperature was measured.
