Madison Thomas 7th period 11-30-17 Research Paper Acoustics Acoustics is a science that deals with the study of sound. It is known to be one of the branches of physics; studying oscillations and sound waves from the lowest to high frequencies. Acoustics is known to be one of the oldest sciences, and dates back to ancient times as people had the need to understand the nature of speech and hearing. The main reason acoustics was discovered and is one of the oldest sciences is because of the need for the knowledge of the sounds of music and musical instruments. Pythagoras, an ancient mathematician, was the first person to ever find out that tone height corresponds to the length of the sting or tube. While Aristotle, Pythagoras apprentice at the time, helped more to explain that an echo is created as the sound reflection from obstacles. Acoustics was sadly forgotten during the Middle-ages of the Earth, but it was happily reborn during the Renaissance period. Acoustics was not reintroduced until an Italian scientist, Leonardo Da Vinci, started to study and reintroduce the idea of acoustics and sound reflections. As …show more content…
The first and easiest way to stop sound is to turn off the source. This method is the simplest, as turning off the radio or stopping air flow in an instrument can be controlled by a human. Another easy way to stop sound is to increase the distance from the source of sound. This can also be controlled by a human, as a person can choose to walk away or outside a space. The person controls the sound attenuation by moving away from the sound and as a result lowering the volume they hear. The final easy way to stop sound waves from traveling is to stop the sound waves from entering your ears. This is the effective method when a person cannot move away from the sound and is used most commonly in hearing protection. These different methods prove stopping sound may seem impossible but it is actually fairly
In “Roars, Snorts, and Infrasounds there are two main ideas: you should not kill elephants for their tusks and ivory and you can tell when elephants are talking and tell them to get away from villages using infrasounds. Many scientists like Katy Payne have very hard jobs; they have to trudge through mud, tolerate the excruciating heat, and have the stomach for the sweat bees crawling all over them. From high platforms scientists observe elephants in their natural habitat. They stay there for hours on end. The scientists spend lots of time listening through ARU’s. An ARU is autonomous recording unit. Payne was one of the first scientists to discover how to communicate with elephants through infrasounds. As a result of hunters of elephants the
Ultrasound Technicians are very valuable in the world of health care. Also known as Diagnostic Medical Sonographer, an Ultrasound Technician uses special machines and equipment that operates on sound waves to determine or diagnose medical problems for patients. There are specializations within this field in which some individuals explore. For instance, areas of specialization includes but not limited to; pregnancy, heart health, gynecology, and abdominal sonography. Although each specializing branch has its own distinctive function, they all involve probing the body to facilitate doctors with diagnoses.
Choosing this field is something that has a profound connection with my personal life. Becoming a Diagnostic Medical sonographer would mean that I have accomplished life long dream. Ever since I was a little, I always wanted to be in the medical field. I have always had a big heart and wanted to help people so when I saw the important role that sonographers play in the medical field, it became clear to me that being a sonographer was exactly what I want to do with my life. In 2007 someone who was very important to me passed away due to gastric cancer. When my grandmother, who was a mother, father, and a friend to me, was diagnosed with gastric cancer my world collapsed. It was devastating news, not only for me but also for the whole family.
Although they lived over four hundred years apart in two completely distinct cultural periods, Leonardo da Vinci and Thomas Alva Edison can be considered the two most paramount inventors in human history due to their substantial contributions to society. To compare these two illustrious figures, it first must be deduced their specific achievements, such as da Vinci’s parachute or Edison’s phonograph, and their effect on civilization, being da Vinci’s inspiration of millions during the Renaissance and Edison’s benefaction to western modernization. Another important constituent that must be examined is each man’s respective eras and how it facilitated, or impeded, scholarly expansion. For instance, da Vinci lived in a pre-scientific age with diminutive technological headway while Edison lived in a more developed and sophisticated scientific time. Nevertheless, both special men were extraordinary thinkers whose
Most people do not realize that a parachute and the Mona Lisa have one common factor—Leonardo da Vinci. His techniques of self-teaching are very impressive and unique from anyone else’s during the Renaissance era. This Renaissance man, Leonardo da Vinci, generously impacted the art and science world by creating new-world inventions, perfecting newly found art techniques, and creating the most famous pieces of art in history.
Sound is created by vibrations that travel in waves, with the longer, more spread out waves being lower pitched sound, and shorter, closer together waves being higher pitched sound. Sound waves travel through the air or water (or whatever is in their way) to reach your ear and vibrate your eardrum, which in turn lets you hear.Sound can not be heard in space because there is no air for it to travel on. Volume is measured in decibels, with a pin drop at about 15 decibels, a 12-gauge shotgun being at about 160 decibels, and a normal conversation at about 65 decibels.
In Navigating through the GCU Learning Management System (LMS) Loud Cloud and the GCU Website. I’m able to familiarize myself with the online school environment in order to be able to complete the assignments that are required. Which will let me know what is needed from me, what’s expected of myself to maintain a high GPA and what’s forthcoming. Having this information that is accessible 24hrs a day is very useful.
What do dinosaurs and super sonic passenger jets have in common? They are both extinct. When the realistic thought of supersonic passenger travel was first introduced in the 1950s, it seemed like a compelling breakthrough in the field of commercial aviation. During this era, American manufacturers created a competitive advantage at the end of the World War II, an advantage that has survived to the present day. For all practical purposes, US technology since 1945 has set the standards for international air operations.
Stuart Hall emphasizes that the popular is constantly evolving. And due to this ever-changing society, the ways in which things are perceived is changing as well. This concept, coined articulation theory, is one of the huge reasons behind artistic expression. Throughout all of history, stories, evidence, and art are forgotten, altered, or misperceived. Because so many important parts of the past are overlooked, artists and writers focus on drawing the attention of modern society to these buried antiquities. However, because the global has changed in such monumental ways, these important ideas are expressed differently. These forms of expression are represented in innovative and thought provoking, yet rather uncomfortable ways. However, the

Scenes of breath-taking Austrian landscapes fill the vivid screen. You immediately recognize the mountains, the valleys, and especially, the singing hills. They flourish with memories of sitting in front of the family television and watching re-run after re-run of the movie that never grew old. The movie, if you haven’t already surmised, is The Sound of Music.
After Isaac Newton algebraically found the speed of sound, he discovered that his answer varied from the answer found in the direct experiment done by William Derham. Newton was 15% off from the observed speed of sound. In an attempt to make fix his error, he took into account that air was composed of more than just oxygen and temperature fluctuated, but he was still off and his reasoning was confusing and illogical. Newton practically lied about his calculated speed of sound. Of the scientists that are taught in schools, Isaac Newton is one of them. Isaac Newton is one of the more well known scientists, while William Derham is not. Other well known scientists include: Albert Einstein and Leonardo Da Vinci, but what about the lesser known scientists.
He must've had something on his processor, forgotten now, but he doesn't have those often. It's very rare for someone like Soundwave to blank out of reality, even dangerous when he isn't paying attention to what is going on around him.
Armed with a red tray and a handful of straws and ketchup, I fly across the concrete battleground of the Gardendale Sonic Drive-In. Despite the myriad of colorful sugar and ice cream adorning my uniform, I smile and thank every customer for choosing Sonic. My coworkers man the grill and take orders over the speaker while I catch the receipts soaring through the air and run 90 miles an hour to each of the 25 stalls.
Many people do not often realize what the most revolutionizing and most important instrument is. In fact, this instrument can be found in every style of music in some way, shape or form. The one instrument that fits this criteria is the drum. According to the Harvard Dictionary of Music, a drum is a generic name for instruments that consists of skin stretched over a frame or vessel and struck with either hands or sticks. Drums are membranous. In other words, a drum has something inside of it, or a "membrane," that gives it its sound (Apel 247). There are many different types of drums, and each drum has its own place in different styles of music. For example, a tympani drum, also referred to as a kettle drum, is mainly found in classical styles of music,
