Industrial Noise and its Effects on Hearing
Audition plays many important roles in our daily lives. From sound, we can identify and locate an object. Also, spoken language and its auditory reception have become an extremely important means of communication. A deficit in the ability to hear have tremendous effects on a person physically and mentally. Hearing loss caused by occupational noise is one of our biggest industrial diseases. It is a disease that has been recognized since the Industrial Revolution. According to Sataloff and Sataloff (1987) about 35 million Americans suffer from hearing loss, and of those, eight million suffer from occupational hearing loss. Because of the sheer number of people and our neglect of the subject, almost every American may be affected directly or indirectly.
It has certainly been technologically possible for many years to eradicate the problem of occupational hearing loss, but a delay has been caused by legislative, economic, and political resistance. Also, because hearing loss does not impede your earning power as much as vision loss would, it has taken the back burner as far as industrial perceptual diseases are concerned. Because of the new laws on worker's compensation an estimated 20 billion dollars might have to be paid out to those inflicted, which would make it the number one environmental and medical-legal problem in the United States (Harris, 1979).
Exposure to excessive noise for a sufficiently long period of time can result in the destruction and eventual loss of the organ of Corti. Harris (1979) has divided the effects of industrial noise on hearing into three categories. The first is acoustic trauma, the immediate organic damage to the ear from excessive sound energy, i...

Many suspect that they were with Washington only to maximize the hate on both sides of the battle. They went against Washington’s orders to not be the aggressors. Soon large units of British and American soldiers were sent to settle what should have been small battles. The French however were prepared to fight back and even had the Indians as allies to help with upcoming battles. In July, Braddock’s army which consisted of over 2000 British soldiers rode west with George Washington and came upon 250 plus French soldiers with over 600 Indians allies. Nearly 1000 British were killed, unlike George Washington who was unhurt during the battle was soon promoted to commander of the Virginia army for his bravery. (Roark 146)

Childcare programs for six to twelve month infants would be structured differently from a behaviorist and an attachment theorist. Based on each theory and its ideas their programs would be shaped with the child’s best interest in mind but fitted to suit their beliefs and principles. Attachment theorists have a negative view on childcare programs. Their program would encourage that of main caregivers found at home and look to grow other attachments and relationships with others. Behaviorists have a neutral stance when it comes to placing children in childcare. Their program would develop reinforcement theories and practices for children so their behavior can become classically conditioned for future events that may rise. Each program would be designated differently and would vary on the hours spent in daycare, the peer-to-peer interactions, and the developmental skills the theorist would implement.

Although level noise do not reach OSHA level (occupational safety & health administration) that causes noise-induced hearing loss, the paediatric nurse in the unit are exposed to continuous moderate noise levels that may causing impairment (Berens, 2008). In addition, these noise exposures may result in abnormalities in the stress response as well as in sleep patterns. (Berens, 2008). If working long shifts weekly and being exposed to noise it will have an effect on hearing loss. The loss of hearing depends on how loud the sound is and the length the person is exposed to sound. Exposure to high level of noise and sound can cause deafness. During or after being exposed to loud noise can leave a ringing sound in the ear. Noise will interfere with communication which could lead to misunderstanding of orders. This could lead to a higher risk of accidents when communication is

Hearing loss is a major global public health issue. Hearnet (2017) defines hearing loss as “a disability that occurs when one or more parts of the ear and/or the parts of the brain that make up the hearing pathway do not function normally” (para. 1). There are many different types of hearing loss, which can have multiple causes, giving each individual experiencing the issue a unique hearing loss case. These types include Auditory Processing Disorders, when the brain has problems processing sound information; Conductive Hearing Loss, a problem with the outer or middle ear which prevents sound making its way to the inner ear; and Sensorineural Hearing Loss, when the Cochlea or auditory nerve is damaged and cannot
The Russian harlequin in Joseph Conrad’s Heart of Darkness expresses a common habit amongst sailors to smoke when he exclaims to Marlow, “Smoke? Where’s a sailor that does not smoke?” (132), correspondingly, in today’s world it is common for daily surroundings to include loud, obnoxious sounds that can potentially damage ones hearing permanently. This type of hearing disability is frequently referred to as N.I.H.L (Noise-Induced Hearing Loss). “N.I.H.L can be caused by a one-time exposure to an intense ‘impulse’ sound such as an explosion, or by continuous exposure to loud sounds over an extended period of time, such as noise generated in a woodworking shop” (“Noise-Indu...
The past twenty years have seen rise to a new burgeoning scientific field: genetically modified foods. During the plant breeding process, geneticists interfere with the reproduction and modify the genes of the new seedling by introducing a fragment of DNA from another organism that possesses the desired trait. With genetic modification, scientists can increase the pest, herbicide, cold, and drought tolerance so that the crop can survive in harsher climates. In some cases, the nutritional value can even be increased (Ulrich 9). Despite the obvious benefits of more nutritious foods and crops that are hardier and more resistant to harsher climates, there are some concerns surrounding GM foods. Each new alteration can cause an unforeseen allergic reaction, negate the effects of antibiotics, or potentially cause some adverse effects to the environment (Falkner 101). Every newly developed GM food must be tested on a case by case basis as there is no universal method that determines the safety of all modified components. As a result, long term effects of ingesting food with altered material are unknown.
Among hospitalized patients around the world, Clostridium difficile is the primary source of infectious diarrhea. Previously, continuously unbalanced intestinal microbiota, usually due to antimicrobials, was deemed a precondition of developing the infection. However, recently, there have been alterations in the biology from virtually infecting the elderly population exclusively, wherein the microbiota in their guts have been interrupted by antimicrobials, to currently infecting individuals within of all age groups displaying no recent antimicrobial use. Furthermore, recent reports have confirmed critical occurrences among groups previously assumed to be of minimal risk—pregnant women, children, and individuals with no previous exposure to antimicrobials, for instance. Unfortunately, this Gram-positive, toxin-producing anaerobic bacterium is estimated to cost US critical care facilities $800 million per year at present, suggesting the need for effective measures to eliminate this nosocomial infection (Yakob, Riley, Paterson, & Clements, 2013).

According to the National Highway Traffic Safety Administration, Lysergic acid diethylamide (LSD) is categorized as a hallucinogen, psychedelic, and a psychotomimetic. LSD is not as commonly used like nicotine and heroin but is still prevalent in the world today. This drug has been around for many years taking users to different worlds and giving a whole new sight on the world around us. Despite the fact LSD is an illegal drug, without it certain movies, songs, and art would not be around that many people know and love today. Many drugs do not have much of a benefitting effect, but LSD does have a few, along with some bad effects as well. Ever since the creation of LSD, scientists have been gaining knowledge of the effects it has on the human body and also the effects on society once it was released to the public.
In the U.S, women live longer than men, 81 years on average for women versus 76 for men, and recent studies reveal a troubling trend. Hearing loss is a hidden disability and many times it is not obvious to others or to the person who has it. The onset of hearing loss is not always noticed and usually progresses slowly over time. Little by little the sounds of the world and the speech of loved ones and friends become difficult to differentiate and understand. There is a tendency to believe that others are not speaking clearly or are speaking in a soft voice. As hearing worsens, the hearing-impaired individual is likely to develop feelings of depression and of being isolated socially. She may gradually stop going to meetings, the theater, movies, places of worship, parties or out to restaurants with friend...
For this assignment, our class was instructed to spend two to three days with impaired hearing. To do this, I obtained some regular green foam ear plugs and wore them while going about my daily routine. The plugs gave me a decent 30dB loss in my “mid” and “upper” frequencies. At first, I did not see how it would be possible to walk around with ear plugs in all day. I started to think what my other instructors would think, but being an audio arts and acoustics major, most hardly batted an eye. Truthfully, I thought I would put my plugs in when I wanted to jot notes down for my journal, but that was not the case. My ears became acclimated to the loss and I could keep them in for most the day. The purpose of this exercise was to reinforce the point our professor had been teaching us all semester; living with hearing impairment is possible, but incredibly challenging.
