...Harmonic Hearing Co. was founded in 1974 by former professor of Audiology, Otis Wren. Based in Plano, Texas, the company manufactured hearing aids, and, while smaller than many of the major players in the hearing aid industry, was successful and profitable throughout its history. This was indicative of the industry- the large, publicly traded companies, such as Great Nordic, Starkey, and Siemens, often reported gross margins around 60%, and net profit margins between 10-15% (Stevenson 2). Technology in hearing aids was ever evolving, however, forcing companies to invest heavily in R&D to take advantage of the most current technology. Never was this more important than within the last decade- with baby boomers reaching retirement, the “graying of America” was sure to lead to a sales boom across the hearing aid industry. With this strong history and expected growth in mind, Harriet Burns (CEO, 2011) and Richard Irvine (Chief Designer, 2011), were excited by Wren’s offer to sell the company to them. Wren proposed a selling price of 14 times the 2010 net income, or $25.2 million. Both Burns and Irvine agreed the price was fair, but they were faced with a situation- how to raise the capital needed to purchase Harmonic Hearing. Wren gave Burns three months to complete the transaction, creating a deadline of January 2011. To further complicate the situation, Harmonic was in the midst of developing a cutting-edge hearing aid that promised strong sales. To get the product to market...

...Physiology of Pitch Perception Hearing is one of the most important functions in an individual’s life. Hearing helps an individual in socializing, working, interacting with others, communicating and can even help in relaxing. Hearing helps people fulfill their lives during daily living. It is a wonderful aspect of life that most people get to experience. However, pitch plays an important and key role in helping with the hearing process. The ear helps determine the frequency content of an auditory stimulus and perception of pitch is determined in the brain. Hearing has different physical aspects, pitch perceptions and different ways to lose hearing. Physical Aspects of Sound Sound can be defined in many ways. It is defined through...

...| 3/5/2012 | | Mechanical Engineering Dynamics lab report.UFMEWL-10-2Vassos Tapakoudes | AIR TRACK Executive summary Demonstrate the patterns and relationships that stiffness and resonant frequencies follow under different circumstances on an air track. Stiffness is a measure of the resistance of a material to deformation under applied force. Resonant frequencies are the frequencies that a system appears to oscillate at greater amplitudes. Content Introduction pg.2 Theoretical calculations and background information pg.2 Experimental design and procedure pg.4 Analysis result and conclusion pg.7 Reflection to other experiment pg.9 Introduction The purpose of this dynamic Lab is to measure the stiffness and resonant frequencies of a coupled oscillator on an air track. Four experiments will be taken in order to see the behaviour and performance of the rubbers connecting the trolleys. Calculate theoretical results by using background information. Comparisons of theoretical and experimental results will be done to see errors and find conclusions. Resonant frequencies are the frequencies that a system oscillates at greater amplitudes. This type of oscillations is what makes systems to vibrate many times. On the other hand, stiffness is a measurement of the ability a material have to extend without deformation. Low stiffness can result in failure of a system and high stiffness is required in the design of systems that deformation...

...Experiment 7 – October 9, 2012 RLC Resonance Purpose Study resonance in a series resistor-inductor-capacitor (RLC) circuit by examining the current through the circuit as a function of the frequency of the applied voltage. Theory The amplitude of the AC current (I0) in series RLC circuit depends on the amplitude of the applied voltage (V0) and the impedance (Z). Where XL =ωL (inductive reactance), XC = 1/ωC (capacitave reactance), R (resistance), angular frequency ω = 2πf (f is linear frequency) and is the phase angle between the current (i) and voltage (v) pf the source. Impedance depends on frequency so the current varies with frequency. The current will be maximum when the circuit is driven at its resonance frequency, ωres = 2πfres = 1 / √LC. At resonance, XL = XC, Zmin = R, I0 = Imax = V0/ R, = 0. The current (i) and voltage (v) are in phase and Vr = V0. Three characteristics of resonance include: Vr reaches maximum value VRmax (at ω ≠ ωres VR < VRmax), the voltage v and voltage vR are in phase in which their peaks (V0 and Vr) are lined up, and the trace of vr and v in xy-plot is a straight line.

...Raising Children the Second Time Around Being a grand-parent today can no longer be considered a traditional role. Long gone are the days when we spoiled our grand-children and sent them “home” with mommy and daddy. With both social (neglect, child abuse, drugs and jail) and economic (lower wages, higher expenses) pitfalls of today more and more grand-children are being raised solely by their grand-parents. According to the 2010, Census there are over four and a half million children raised in grand-families. My role as a grand-mother, to Piper Reanne, was drastically changed from spoiler and nurturer to that of the parent in the fall of 2005. After financial hardships, incidents of neglect and other safety concerns, my daughter and I sat down to discuss me becoming Piper’s “primary” caregiver. After contacting the Clerk of the Court, we wrote the Caregiver Authorization, which is nothing more than a notarized letter, filed a copy with the court and Piper moved into my home. The long forgotten sound of a child laughing, a full on belly laugh, once again filled my home. My days of sleeping in late, getting up and going wherever and whenever I wanted were a thing of the past. I had to adjust back to packing a bag before going anywhere and doing everything for two. Our lives moved forward. In the fall of 2007, Piper was taken, by her mother without permission from her paternal grand-parents while they were on a shopping trip to Wal-Mart. While...

...The influences of music in a child's life. Music comes in all shapes and forms. When most people think of music they think of what you hear on the radio but music is all around us. From a young age we have learned what music is, from hearing the sounds of our mothers voice, to hearing pots and pans bang in the kitchen while dinner is being prepared. When I looked up the definition of music it said "The art of arranging sounds in time so as to produce a continuous, unified, and evocative composition, as through melody, harmony, rhythm, and timbre." Which means that music can pretty much be made out of everything we can get our hands on. How does this effect children, you may ask? How does it not effect children! Some benefits of music are it Stimulates the brain, "Music simply stimulates parts of the brain that are related to reading, math, and emotional development.", improve memory "Further research has shown that participation in music at an early age can help improve a child's learning ability and memory by stimulating different patterns of brain development," helps them socially by teaching them how to work together (in a band, choir, ect.) is a confidence builder, teaches patience, teaches discipline, fosters creativity and so much more. It is a shock to me that due to budget cuts, music class is the first to be cut in most schools. In my opinion music class should be just as important as math science or English. "Schools with music programs have significantly...

...Capella University MBA6010 – Professional Effectiveness: Strength, Impact, and Reposition Professor Pamela Solberg-Tapper Assignment u06a2 – Professional Challenge – Coaching Analysis Final Paper By Dawn Patterson October 1, 2010 I. Overview In summarizing my learning from this course about the coaching and feedback process, I learned the most about myself during the classmate phase of the coaching process. Many things were illuminated over the course of the coaching sessions with my classmates and coworker. Turns out that the concern I brought to the forefront to receive coaching and direction on was one of many symptoms related to a greater issue that wasn’t as easily identifiable as other indicators had suggested. What I believed to be a problem with managing a stressful work environment really was an issue with effective communication. The coaching process is comprised of three elements; planning, conducting the discussion(s), and evaluating. In the planning phase I developed a short-term plan to help the coachee achieve their expressed goal. The next phase of the process, conducting the discussion entailed the actual delivery of the feedback. Lastly, the evaluation phase provided an opportunity to track the progress and adoption of the prescribed approach to train and develop the coachee. The evaluation phase also created an opportunity for the coachee to share feedback with the coach on the effectiveness of the coach’s delivery...

...There is a radio commercial that many of you will remember. “When E. F. Hutton speaks, people listen.” This morning we have to think about the question, when God talks, do we listen? It’s a serious question, and one that we always hope the answer for is a resounding, “yes!” Today is Transfiguration Sunday, the last Sunday before Lent. We celebrate this now precisely as a reminder that the one who leads us through the coming season of penitence and preparation is preparing us to participate in such glory with him both now and at his second coming. Hear the recounting of these events from Matthew: After six days Jesus took with him Peter, James and John the brother of James, and led them up a high mountain by themselves. There he was transfigured before them. His face shone like the sun, and his clothes became as white as the light. Just then there appeared before them Moses and Elijah, talking with Jesus. Peter said to Jesus, “Lord, it is good for us to be here. If you wish, I will put up three shelters—one for you, one for Moses and one for Elijah.” While he was still speaking, a bright cloud covered them, and a voice from the cloud said, “This is my Son, whom I love; with him I am well pleased. Listen to him!” When the disciples heard this, they fell facedown to the ground, terrified. 7 But Jesus came and touched them. “Get up,” he said. “Don’t be afraid.” When they looked up, they saw no one except Jesus. As they were coming down the mountain, Jesus...

...VARK ASSESMENT There are several ways to determine what an individual’s learning style is. For a student to perform at their best it is helpful to know what learning style works best for them and to understand their particular learning style. The VARK module is one of the most common models used today. It was developed by Neil Fleming in 1987 as a way to assist students in learning more about their individual learning styles (Cherry, 2012). VARK stands for visual, Aural, Read/Write, and Kinesthetic. A student can have a single learning style or multiple learning styles. If the student has multiple learning styles their learning preference would be called multimodal. The majority of learners fall under the multimodal as much as 60% of any population (Fleming, 2011). Educators can use the module as well they can use it teach more effectively. With it they can gain a better appreciation of how they process information which is what they use to teach. They can use their findings to develop teaching methods that can reach a broader student population encouraging their students to learn (Marcy, 2001). The VARK assessment was used to asses a student who is currently enrolled in college classes. The student was assessed for this paper and was found to have a multimodal (AK) learning preference meaning more than one learning preference. A multimodal learning can have several different combinations of styles. In this case the student scores showed Visual: 4, Aural:...
