Tinnitus :: Health Hearing Loss Noise Loud Essays

Tinnitus A police officer fires his handgun while target practicing. He forgot to put on his ear muffs and suddenly after the shot, he hears a faint buzzing sound. In this example, over time, the ringing will probably fade for the officer. Almost everyone will experience tinnitus in their lifetime. After all, loud noises are impossible to avoid completely. There is only a problem when the sound from the tinnitus does not stop, or it continues to get louder with time. For many people around the world, the ringing, buzzing, hissing or chirping sounds that make up tinnitus (tin-Night-us; Tin-nit-us) or acoustic trauma never go away (Alliance). There are several definitions of the word tinnitus. Tinnitus Away defines it as "a noise heard in the ear, or the sensation of noise as a ringing that is purely subjective." Hear USA says tinnitus is "a noise heard in the ears." According to Tinnitus.com, Tinnitus was defined in 1999 as a sensory disorder. What does all of this mean? Basically, tinnitus is the perception of sound by an individual when there is no external source of that sound. Sound burst hearing loss is due to damage to the auditory receptors, the hair cells, inside the ear. The vibration of these hair follicles is what allows humans to hear so when they become damaged, the auditory sense is set off, and the resulting noise is the sound heard by millions of tinnitus sufferers. The other damage done to the ear by sound bursts that creates hearing loss is the deflation of the cochlea. This damage is usually caused by prolonged exposure to a continuous loud noise. Acoustic traumas are caused by an explosive sound, sudden and loud, that can cause hearing loss (Goldstein, 2002). The effects of these traumas can fade. However, they do not always go away. A college student who had a fire cracker explode in his hand only fifteen inches from his ear still had a ringing sensation two years after the incident. According to the Internet Armory, sound is physically just a rapid change in air pressure above and below the atmospheric pressure. The decibel, dB, named after Alexander Graham Bell, is used to describe this change in pressure. Zero dB is the threshold of human hearing, and 120 dB is the pain threshold. Decibels increase logarithmically so 10 dB is 10 times as powerful as one dB, and twenty dB is ten times as powerful as that.

2- Define the distinctions between primary, secondary, and tertiary sources in a secondary search Primary source as stated is original data. Primary source is based in facts from the time period involved and have not been filtered through interpretation or evaluation. Therefore, primary sources is considerate the root of original materials on which other research is based, the first formal appearance of results in physical, print or electronic format. Primary sources present original ideas and thoughts, report a discovery, or conduct new information. Secondary sources are considerer less important than primary sources. Secondary Resources are material written after the fact that provides point of views of hindsight. The fact is that are interpretations and evaluations coming of primary sources. Secondary sources are not original materials, but rather opinions on and discussion of evidence in such information. According with the text, secondary search is easy to interpret as a tertiary source as well. Tertiary sources conduct an analysis of material which is a distillation and compilation of primary and secondary sources. Generally, consist in a summary of information provided with own point of view of such materials 3- What problems of secondary data quality must researchers face? How can they deal with them? The fact is that in some cases is vital to aware of the problems that can arise with secondary research so if it is that case the researcher will be able to work with these problems. Secondary search is in many cases the only material that a researcher can find on certain information; therefore, for a researcher this issue can have further problems and consequences putting together a new project as well. The problems of secondary data quality that a researcher must face is; â€Å"verifying and determining the value of the secondary sources the researcher would like to use† (Cooper & Schindler, 2006). Researchers who use secondary sources must make their best efforts to verify the accuracy of the information. On the other, hand, is a fact that all sources need to be cited appropriately in a paper, even if they are only secondary in nature. For example, a researcher who cites an article about a political event should dig further to verify the information. To do this they may need to get primary source data of the politic event. It may not be the primary data to verify secondary data in research, but every effort must be made in order to prove the credibility of the sources being used in any research effectively. Chapter: 7 Discussion Questions 1- How does qualitative research differ from quantitative research? Generally, can be some researchers who feel that one is better than the other. A major difference between the two is that qualitative research is inductive and quantitative research is deductive. Quantitative research differs on numbers or quantities. Quantitative studies have results that are based on numeric analysis and statistics. In many cases, these studies have many participants. Perhaps is not abnormal that has there to be over a thousand people in a quantitative research study. It is good to have a large number of participants because this gives analysis more statistical accurately. Qualitative research studies are based on differences in quality, rather than differences in quantity. Results are in words or pictures rather than numbers. Qualitative studies usually have fewer participants than quantitative studies because the depth of the data collection does not allow for large numbers of participants. It important to remark that both, quantitative and qualitative studies have strengths and weaknesses, a particular strength of quantitative research is that statistical analysis allows for generalization to others. The goal of quantitative research is to choose a sample that closely resembles the population. Qualitative research does not seek to choose samples that are representative of populations and this make a considerable difference in both. 2- How do data from qualitative research differ from data in quantitative research? Data from qualitative research and quantitative research differs in many ways. When conducting research there will be a time when you have to decide between the use of qualitative and quantitative research. Understanding the differences in data that is gathered from these resources will help you decide what type of research you will need to use. â€Å"Material subtracted from qualitative research can contain different uses because the researcher can use as many knowledge as searcher can during research to adjust the data extracted from the next participant† (Cooper & Schindler, 2006, Ch. 8). Although, this event influences the details of the data obtained by the research effectively, allowing data and research to condense through obtained information properly. In quantitative research identical data is â€Å"desired from all participants, so evolution of methodology is not acceptable† (Cooper & Schindler, 2006, Ch. 8). Quantitative requires specific data to be retrieved at all time, and qualitative research allows for change. This difference also impacts the way that data from these research methods will be interpreted and analyzed. 5- Assume you are a manufacturer of small kitchen electrics, like Hamilton Beach/Proctor Silex, and you want to determine if some innovative designs with unusual shapes colors developed for the European market could be successful marketed in the U.S. market. What qualitative research would you recommend, and why? For this event, is good idea to suggest a focus group so doing that may collect information from a wide variety of participants regarding specific question (Henderson, 2009). Is important that to be sure that it has a good cross-section of people to be in the group and that their observations are honest and not biased in any way. This task may be difficult, but necessary to give it an honest try. In addition, by affirming theories to compile trough what people say and do, qualitative research is not based accusing of imposing theories upon participants. Is therefore, by maintaining detailed records of what its said and of what happens qualitative research does not limit the complexity of social life to anybody can manipulated equations. â€Å"Rather than skating on the surface of everyday life, its close contact and detailed recording allows the research to glimpse beneath the polished rhetoric, or the plausible deceits; it is able to take more time to focus upon the smaller yet powerful processes which other methods gloss over or ignore† (Schostak, 2009).
