This research paper will cover sound. It will cover what sound is, how sound waves are created, Parts of a sound wave, Ears, Jobs, and the speed of sound. There will be pictures, equations, and illustrations to help explain the research. sound is an amazing gift from God, and it is important to know what it is. Sound is differing waves of pressure, or vibrations, made by molecules moving back and forth. There are 3 main points of sound: Quality, Amplitude, and Frequency and Pitch. Quality is how well it sounds. Amplitude will be addressed later. Frequency is how often a vibration occurs. Frequency is referred to as Hertz (HZ). Pitch is how high or low sounds are, but is not loudness, though that is a part of sound as well. Frequency and pitch go side by side. If the frequency is high, the pitch is high, if the frequency is low, the pitch is low.
The volume, or loudness, of sound is measured in decibels. It is named after Alexander Graham Bell, the creator of the telephone. It was in the beginning just bels, and went from 0 bels to 13 bels, but was not precise enough, so decibels were created. Decibels are a tenth of a bel, and ranges from 0 decibels to 130 decibels. The next point of sound is how sound wave are formed, and what the parts of the sound wave are. The …show more content…
Well wait a minute, what about stuff like speaking? It does not go behind the speaker. And it is confusing, until realizing how people speak. Speaking starts when our voice box (Larynx) vibrates. If someone could set a voice box on a table and vibrate it, it would go out in all directions, because nothing is blocking the sound waves. But the voice box is inside the body. Its surrounded. So those sound waves that were not pointed up just bounce around the esphogas? until they end up going up throat and into the mouth, where the tongue and lips form them into words and they go out of the mouth and into the

Singing Learning Theory

...Learning Styles Definition This approach to learning emphasizes the fact that individuals perceive and process information in very different ways. The learning styles theory implies that how much individuals learn has more to do with whether the educational experience is geared toward their particular style of learning than whether or not they are “smart.” In fact, educators should not ask, “Is this student smart?” but rather “How is this student smart?” Discussion The concept of learning styles is rooted in the classification of psychological types. The learning styles theory is based on research demonstrating that, as the result of heredity, upbringing, and current environmental demands, different individuals have a tendency to both perceive and process information differently. The different ways of doing so are generally classified as: 1. Concrete and abstract perceivers–Concrete perceivers absorb information through direct experience, by doing, acting, sensing, and feeling. Abstract perceivers, however, take in information through analysis, observation, and thinking. 2. Active and reflective processors–Active processors make sense of an experience by immediately using the new information. Reflective processors make sense of an experience by reflecting on and thinking about it. Traditional schooling tends to favor abstract perceiving and reflective processing. Other kinds of learning aren’t rewarded and reflected in curriculum, instruction, and assessment nearly...

In spite of the great importance of theory-building and theory testing within your field of specialization, there is no generally accepted conception of what a theory is. Because your dissertation must contribute to theory, you must have a clear understanding of the variety of conceptions of theory, types of theories, and ways of contributing to theory and be able to justify how, exactly, your study contributes to theory. Part 1 Using Gelso (2006), Harlow (2009), Stam, H. (2007, 2010), Wacker (1999), and five additional peer-reviewed articles from your specialization, discuss scholarly views on the nature and types of theory. Compare and contrast at least three views of what constitutes a theory, including the view you will use in Part 3 of this question. Be sure to distinguish theory from related concepts, such as hypothesis, paradigm, model, and concept. Part 2 Using Ellis & Levy (2008), Harlow, E. (2009), and five additional peer-reviewed articles, review the scholarly literature on the relationship between theory and research and the ways research (quantitative and qualitative) can contribute to theory. Discuss at least three ways research can contribute to theory. Part 3 Pick a theory (in one of the views of what constitutes a theory that you identified in Part 1) of...

Audit Research After Sarbanes-Oxley Evaluation

...EVALUATION OF REASEARCH PAPER Title: Audit Research after Sarbanes-Oxley Author: Mark L. DeFond and Jere R. Francis A. Describe the research problem or question. Evaluate the importance of the research question to audit practice. This paper attempts to stimulate research into some of the important questions implicitly raised by SOX regarding the audit profession’s potential failings. Enron’s failure and the accounting scandals at Worldcom and other companies provide compelling evidence that auditing matters and is important. However, it is unclear that whether auditing was sufficiently “broken” in the first place to warrant the radical reforms and changes effected by the SOX. The disconnection is large between the scientific evidence on audit quality and institutional changes premised on the assumption that auditing is broken. This research gives us the direction which we need to collect scientific evidence to guide public policy-making in audit. B. Explain the author’s approach to solving the problem. The authors discuss the following areas and give some suggestions for future research in each of them: 1. Why auditing matters now more than ever 2. Institutions that affect auditing 3. Engagement-specific characteristics that affect audit quality 4. The role of auditing and corporate governance 5. Audit quality and other accounting firm characteristics C. Describe the major findings of the research. 1. The criticism embodied in SOX is usually intense, and appears...

...About Dyslexia & Reading Problems Developmental dyslexia is a condition related to poor reading. Children with dyslexia have difficulty learning to read due to one or more information processing problems such as visual perceptual or auditory perceptual deficits. Many but not all children with dyslexia have difficulty with reversals of numbers, letters or words. New research points the way to specific methods of instruction that can help anyone learn to read well no matter what the underlying problem may be. Following the links will provide interesting new information as well as extremely effective solutions for all types of reading problems including developmental dyslexia. What is dyslexia? Children who have an average or above IQ and are reading 1 1/2 grades or more below grade level may be dyslexic. True dyslexia affects about 3 to 6 percent of the population yet in some parts of the country up to 50% of the students are not reading at grade level. This means that the reason for most children not reading at grade level is ineffective reading instruction. The dyslexic child often suffers from having a specific learning disability as well as being exposed to ineffective instruction. Children may have dyslexia or a learning disability if they have one or more of the following symptoms: * Letter or word reversals when reading. (Such as was/saw, b/d, p/q). * Letter or word reversals when writing. * Difficulty repeating what is said to them. * Poor handwriting...

...1 Introduction Sound as an information channel has distinct advantages over other methods of communication, making it widely-used for warnings and alerts in various contexts and environments. Auditory warning signals in user environments are, more often than not, very simple, monotone sounds. In application, they are often annoying and difficult for users to recognize and understand (Block et al., 1999; Ulfvengren, 2006) During recent time there has been an increasing interest to investigate new and more complex nonspeech sounds to convey information in critical situations (Stevens et al., 2006; Ulfvengren, 2006; McKeown, 2005). The Sonic studio, part of the Interactive Institute in Sweden, is a research unit focusing on applied research within sound, interactivity and new technology. Sound for information-delivery is a recently started research project at the studio. One particular focus is to explore alternative methods to design warning signals for user environments. So far, a literature study has been carried to with the aim to investigate the progress which has taken place within this branch of sound design research, identify issues related to this type of research, and to point out some new potential ways to design warning signals. The objective of this paper has been to present and discuss the important findings of this study. 2 Speech and non-speech sounds A common approach in auditory display research today is to distinguish between speech and non-speech...
