INTRODUCTION

N oise is acoustically made up of numerous sound waves with anarchically distributed amplitude and phase ratios, causing an unpleasant sensation1. Noise can be continuous - when there is no variation in terms of sound pressure nor sound spectrum; floating - when it presents variations in terms of acoustic energy in function of time; or impact noise - with acoustic energy peaks lasting for less than a second, at intervals greater than one second2.
Impact noises are usually produced by quick gas expansion, such as that produced by firearms or bomb explosions. These types of sound can reach intensities of 140 dB SPL (sound pressure level) in frequencies around 2 and 3 kHz and, for this reason; they are harmful for human hearing3.

studied ear problems among Army personnel who were exposed to multiple traumas during eight years of war in Iran. Hearing loss, tinnitus, ear discharge, vertigo, tympanic membrane perforation, audiologic findings and the type of trauma were considered. Bone Conduction threshold over 15dB was considered as hearing loss. In the sample population, 21.5% complained of audiologic problems. 94.6% had hearing loss, 83.6% tinnitus without hearing loss, but there was a hearing loss on the audiologic findings. 80% of hearing loss was bilateral, 10.9% only on the right and 9.1% only on the left side. 89% of hearing loss was sensorineural (88% in high frequency). 6.4% of them had tympanic membrane perforation and none had complained of vertigo 32.
AUDIOMETRY
Pure Tone Audiometry (PTA) is the commonest test performed to assess hearing loss following exposure to noise from firearms. Standard technique for assessment of pure tone threshold at individual frequency is by modified Hughson-Westlake method33. Pure tone average is taken as average of pure tone thresholds at 500, 1000, 2000 Hz frequency.
Degrees of hearing impairment as defined by WHO (World Health Organization) is given in table below.

Impact of Hearing Loss

...The Impact of Hearing Loss In today’s society, it is a well-known fact that the onset of hearing loss is occurring at an earlier age in an individual’s lifespan. In addition, the percentage of society who is experiencing hearing loss is rising as well. The culprit behind this major health concern is widely believed to be from external factors such as our overly loud environment. In the following essay, two main points will be addressed. The first will be regarding the long term consequences from a population growing up with premature hearing loss. And the second will be the challenges that will be faced when trying to change the behaviors of listeners. According to Oyler (n.d.), the impact of hearing loss has a large effect on an individual’s social life. What this means is that a person who is hard of hearing may be more socially withdrawn and reclusive than before they experienced hearing loss. This may occur for many reasons such as avoiding awkward interactions where it may be difficult to communicate effectively. Sometimes it may be due to the individual not being able to come to terms with the fact that they may need a hearing aid. Therefore, the individual shuns all interaction that may remind them of this health concern. If the rate of hearing loss increases in society, the quality of life that one may expect may decrease as a result. For example, lack of social interaction may lead to depression, lack of fulfillment, loneliness and many other related concerns. The...

Hearing and Visual Impairment

...Running head: Hearing and Visual Hearing and Visual Impairment Bonnie J. Hatch Grand Canyon University SPE 526 May 19, 2010 Abstract The abstract of this essay will include information on hearing and visual impairments. It will explain the legal definition of both, the impact that hearing and visual impairment have on a person’s development and education achievement, how humans hear and see and the degrees, types and causes of each. The essay will also go into detailed by supplying a lesson plan which will include the objectives/goals, accommodations/modifications, strategies, assessments, activities as well as including brief description of the student by submitting the student’s age, grade, disability strength, and weaknesses. Hearing and Visual Impairments Hearing is a complex process of changing sound waves into the neural signals which can be translated by the brain into sounds. Within the inner ear is the Cochlea, which changes sound waves into neutral signals. The signals are sent to the brain through the auditory nerve. Where the visual impairment is also a complex process, light enters the eye through the pupil and is collected by photoreceptor neurons in the retina. Signals are then sent to a neuron network that then generates electrical impulses which goes to the brain. The legal definition of a hearing impairment is “a full or partial decrease in the ability to detect or understand sounds. It can range from a mild hearing loss to total deafness”...

Audiologists work with patients of all ages, from newborns to elderly. Keywords: Audiology CAREER RESEARCH ESSAY: CAREER DEVELOPMENT Audiology was born out of armed forces rehab programs during and following WWII, as many soldiers sustained injuries to their inner ears from loud noises. The practice was largely influenced by the invention of hearing aids-originally, audiologists could recommend amplification, but could not provide it. The Academy of Doctors of Audiology was formed in 1976, and audiologists moved beyond technician status. The practice then expanded to include both diagnosis and treatment. “Audiologists specialize in balance and hearing disorders. They diagnose hearing, neural, and balance disorders in patients from all age groups and recommend solutions to correct or cope with problems. To diagnose and correct balance and other hearing related problems, audiologists...

A Discussion of the Issues Relative to Genetic Diversity

...A Discussion of the Issues relative to Genetic Diversity an essay by Timothy D. Roxbury A Discussion of the Issues relative to Genetic Diversity Introduction When we discuss genetic diversity, we describe the genetic differences of certain members of a population, whether they are mammal (humanoid or animal), plant or any other type of living organism. Upon first discovery of genetic differences, we notice that the alleles for each diverse characteristic may be placed under one of two categories: high genetic diversity or low genetic diversity. In the case of high genetic diversity, we will find a variety of differing alleles for each characteristic. Conversely, nearly all of the members of a population will have the same alleles when the case of low genetic diversity is considered. The following discussion will take into consideration the concept of genetic diversity, how it is introduced into a population and what, if any, are the resulting factors. The four means of introduction are: • Migration • Mutation • Population Size • Sexual Reproduction In the following synopsis, each means of introduction will be considered separately followed by a conclusion of the assignment. Migration as it relates to Genetic Diversity Migration is defined as the movement of a living organism from one place to another. During the process of migration, the living organism is subject to spread its alleles among other like living beings. This,...

The Architecture of the Mind and Its Relationship to Sight

...The Architecture of the Mind and its Relationship to Sight Our minds are able to engage in an abundance of amazing tasks because of their complex structure. Depending on the architecture of ones brain, their mind is able to perform different functions. In Oliver Sacks’ essay “The Mind’s Eye” he discusses whether or not we can control our own minds. He relates this subject to various individuals’ experiences with blindness. Sacks explains in his essay that a person does not necessarily need to see in the retinal sense in order to use their sight. His ideas relate to those of Juhani Pallasmaa in his essay “The Eyes of the Skin,” in that Pallasmaa believes that sight has become a dominant sense and that we have repressed our other senses. Both authors discuss the ability that the senses posses and how the use and disuse of one of these sense can affect the others. Sight is also a major sense for both authors and they explore how the senses of vision relates to the use of other senses. In this essay I will show how that the “architecture of the mind” is nothing more than the structure of one’s mind and that sight is a major component of this structure, regardless of it being retinal or imaginative, and that when one sense is lost our minds restructure and strengthen the other senses. The mind shares many functions with architecture, such as the processes of observing, designing, constructing, selecting and supervising. The mind conducts these processes with our senses...

Why Does Nihl Occur

...ESSAY 2 + Introduction 

+ What is the extent of the problem?

+ How does NIHL occur? 
NIHL can occur only humans expose themselves to very intense loud sounds for long periods of time. Individuals expose themselves to loud sounds in everyday life, especially during participation in recreational activities such as playing in bands, seeing a very loud live show, shooting weapons, listening to headphones, mowing lawns and using woodworking tools. Sounds that are heard that are less than 75 db, are less likely to cause hearing loss, when sounds that are above 85 db can affect human hearing. If the sounds are louder, the worse it is for hearing and the less time it takes for NIHL to occur. Average db rating for a normal human conversation is 60...

Forbidden Love

...Mark Taylor October 20, 2013 Essay 1 Forbidden Love In reading classic British literature a theme has come across of forbidden love and the perils it holds. Forbidden love harms those who wield it and sometimes it even harms those the love is aimed at. Forbidden love, also known as “fals amor,” is shown in pieces like “Morte Darthur” or “The Franklin’s Tale,” from “The Canterbury Tales.” The forbidden love shown in these tales is always were one person is married and the other is not. “The Franklin’s Tale,” “Morte Darthur,” and “Sir Gawain and the Green Knight” all reveal how forbidden love will end tragically. Each of these works has a married woman who is either loved by another or is in love with another. However, no matter the case the one with the forbidden love is aggrieved in the end because they love cannot become mutual or accepted by others. “The Franklin’s Tale” tells of a woman, Dorigen, and a knight, Arveragus, who marry for love. Arveragus must go to battle for a few years and a nobleman, Arelius, comes to light that loves Dorigen. Arelius and Dorigen make a bet where if Arelius wins Dorigen must become his bride. She agrees confidant in his ability to fail in this task. Arelius succeeds, though, with the help of a sorcerer after two years of despondency. When Arveragus arrives home he finds Dorigen distraught, upon hearing the bet he decides that she must keep her side of the bet, though it pains them both greatly. Upon hearing of Arveragus and Dorigen’s pain...

Developmental Delay Research Paper

...disabilities. Personally, I feel that it would not be fair if we don’t try our best to help these people live the lives they could live. I chose this topic because I have always been close to children and also this is something I will encounter in the future since I would like to be a paediatrician. I will be focusing on developmental delays since I feel they are the most common in children. Developmental delays are very common issues seen prominently in young children, around the ages of three to five, around the world. According to the Centre for Disease Control and Prevention, about 15% of children of the ages three to seventeen years, have one or more developmental disability. These include: ADHD, Autism Spectrum Disorders, Cerebral Palsy, Hearing Loss, Intellectual Disability, Learning Disability, Vision Impairment, and delays of motor skills, speech and language skills, and several more. According to the University of Michigan Health System, a developmental delay is when a child does not reach their developmental milestones at the expected. Additionally, the University says that it is an ongoing major or minor delay in the process of development. Based on this knowledge,...

Choose one overseas market and discuss how macro-environmental factors (otherwise known as PEST – political/legal/regulatory; economic; social/cultural; and technological) would impact Cochlear’s global marketing mix. Introduction Cochlear is a leading global biotechnology company that specialises in the design, manufacturing and supply of Nucleus Cochlear Implant, the Hybrid electro-acoustic implant and Baha bone conduction implant. The company was formed in 1981 with the support of the Australian government to commercialise hearing implants, and today it holds over two thirds of the worldwide hearing implant hearing market (Cochlear, 2013). It is predominantly run in Sweden and Australia, with one of their major offices here at Macquarie University. With sales of $297 million in Americas, $286 million in Europe, the Middle East and Africa and $123 million in the Asia Pacific Cochlear supplies to 100 of countries worldwide, which allows them to use $119.3 million on research and development in 2012.

Effective Communication Based on Culture

...shared by communities affected by deafness. They use sign languages to communicate. Members of this culture, has an impressive way of viewing their condition. They term it as a different human experience rather than disability. Looking at them in the sense of a community or culture, they are often seen as a team of minority. This makes some of these communities to feel like they are ignored by the group that don’t understand their sign language. On the other hand, deaf people face another challenge when it comes to acquiring education. Institutions are primarily of hearing people and therefore, special institutions which are often not enough have to be constructed. So in case a deaf person is among the family of hearing people, they are forced to learn the language so that their sibling can feel included. Therefore, the family members indirectly become members of the deaf culture. Hence, the extent of hearing loss does not define deafness. The best way to define deaf culture therefore, is to identify a social group that a person chooses to belong. As long as other members accept the person in their group. Looking at the history, deaf culture is obtained from schools...

Down Syndrome Essay

...genetic cause of severe learning disabilities in children, occurring in one in every 700 to 800 infants. Increased understanding of Down syndrome and early interventions make a big difference in the lives of both children and adults with Down syndrome. Down syndrome is also known as Trisomy 21 syndrome. Trisomy 21 is due to an extra copy of chromosomes number 21. Instead of having the normal two copies chromosomes number 21, the person with Down syndrome has three copies of chromosomes 21. Meaning normally a fertilized egg has 23 pairs of chromosomes. In most people with Down syndrome, there is an extra copy of chromosome 21. (Rogers, 2007, pg.6) The formal story began in 1866, when a physician named John Langdon Down published an essay in England in which he described a set of children with common features who were distinct from other children with mental retardation. Down was superintendent of an asylum for children with mental retardation in Surrey, England when he made the first distinction between children who were cretins (later to be found to have hypothyroidism) and what he referred to as "Mongoloids." Down based this unfortunate name on his notion that these children looked like people from Mongolia, who were thought then to have an arrested development. This ethnic insult came under fire in the early 1960s from Asian genetic researchers, and the term was dropped from scientific use. Instead, the condition became called "Down's syndrome." In the 1970s, an American...

...relationship to nonverbal activity. Personal–contextual and the static–dynamic dia- lectics. Although nonverbal communication can be highly dynamic, personal space, gestures, and facial expressions are fairly static patterns of specific non- verbal communication codes. Their interpretation will vary depending upon its context and culture that it is being communicated to. The chapter talks about how different the dynamics of intercultural nonverbal communication are across different cultural groups. In this ICC artifact assignment we will examine and look at the topic of The Cochlear implant controversy. The controversy involves the scientific hearing assistance breakthrough device for the deaf community, and whether or not its use and development will be the ultimate removal of and extinction of the deaf community as a culture. The following essay will examine the relevance and truth to this argument and examine the negative and positive manifestations to the Deaf culture from the development and use of the Cochlear Implant itself. The Chapter talks about several research findings about nonverbal communication. Research investigating the universality of nonverbal communication has focused on four areas: (1) the relationship of human behavior to that of primates (particularly chimpanzees) (p. (2) nonverbal communication of sensory-deprived children who are blind or deaf, (3) facial expressions, and (4) universal functions of nonverbal social behavior. Chimpanzees and humans share...

Effective Communicaion

...Explore the importance of developing effective communication skills in nursing. Communication is the base for everything done in everyday life as well as in professional practice. What and how something is said will send a number of messages to the receiver; these messages are sent and received both knowingly and unknowingly (Sully and Dallas, 2005). Nurses evidently deal more with patients than any other health care worker (McCabe and Timmins 2006), therefore it is very important that effective communication skills are developed, as they will be supporting the patients, the relatives and then communicating back to other health care workers. This essay will be looking at the importance of developing effective non verbal communication skills, the effect different levels of communication has on patients, and adapting communication skills where barriers exist. Communication is both verbal and non verbal, Verbal communication is often seen as the most important form of communication (McCabe and Timmins, 2006). However when people are communicating, words make up only seven percent of the message. The other ninety three percent is made up by how the message is said, the tone of the message and body language (Argyle, 1989 cited by McCabe and Timmins, 2006). So from looking at the information Argyle presents, it is clear to see that non verbal communication has much more of an impact than verbal communication. Although what is said will still have to have meaning and be appropriate...
