Auditory learning

Due to the nature of the condition, individuals with Down syndrome face tremendous difficulties with hearing. Down syndrome occurs due to an extra copy of the twenty-first chromosome causing intellectual and developmental delays as well as abnormal physical characteristics. The etiology of this disorder is genetic due to the addition of the extra chromosome, however causes of this additional chromosome are unknown. Down syndrome affects both sexes and is present from birth. With the highly…

All five of our different senses are important to have for a variety of reasons. They allow us to see, to feel, to hear, to smell, and to taste. There are also a lot of different parts of the body that allow us to experience these senses. If I had to choose which sense to lose though, I would choose to lose my sense of taste. One of our five senses is taste. The primary function of taste is to have us evaluate what we are eating. There are a few different areas that give us the ability to…

Adult Case Study (Ear) What additional historical data would you like to collect? A general history of ear, nose, mouth, and throat including current or recent exposure of respiratory infections should be collected. In order to find out if the vertigo is from a systemic cause, ask key questions like: What other health problems do you have? Are you anxious or nervous? What makes the dizziness worse or what makes the dizziness and ringing in your ear go away? Cardiovascular problems such as…

have a child born with the same birth defect (Hadfield, Microtia: My Family Story). Without a reason though it is difficult to prevent microtia from happening. Aural Atresia, the absence of the external auditory ear canal, is found to accompany the more severe grades of microtia. The external auditory ear canal is not the only part of the ear affected. Aural atresia also affects the middle ear. The middle ear contains three small bones, the ossicles consisting of the incus, stapes and malleus.…

Middle Ear Case 2A A 60 year old female was seen today for an audiological evaluation following the persistence of fluctuating, hearing loss and tinnitus in her right ear over the last year. She also reports occasional dizziness and aural fullness that affects her right ear more than her left ear. She is currently seeking a hearing aid for her right ear but is wondering if anything may be done to correct her hearing loss. Some additional necessary information may be what was she doing when the…

1. The pinna or auricle directs sound waves into the auditory canal. The eardrum vibrates according to frequency. Vibration transmitted to malleus then incus and then stapes of the middle ear. When the stapes vibrate, the membrane of the oval window is pushed in and out. This created the fluid pressure in the perilymph. Pressure waves enter the Scala vestibule then Scala tympani and then round window. This is where the walls become deformed in Scala vestibule and Scala tympani. Pressure…

Trepanation is one of the oldest know surgical techniques. It was practiced in countries all over the world but seems to have originated from places in and around Europe. Trepanning is the process of drilling, grooving, boring and cutting or scraping a hole, usually no bigger than an inch or so, into a person’s head, therefore exposing the dura matter and allowing brain tissue to freely pulsate –increasing blood flow. Figure 1 shows the four methods, 1-scraping 2-grooving 3- boring and cutting…

Otitis externa (OE) is an inflammation or infection of the external auditory canal (EAC), the auricle, or both. There are a few types of OE; acute diffuse OE, acute localized OE, chronic OE, eczematous OE, necrotizing (malignant) OE an Infection that extends into the deeper tissues adjacent to the EAC and Otomycosis an Infection of the ear canal from a fungal species. The acute OE is most common in swimmers while the acute localized OE is associated with infection of a hair follicle. The chronic…

Aim - The aim of this experiment is to find out at what age the ability to hear high frequencies begin to degrade. Hypothesis - As people get older the ability to hear high frequencies is much lower than the ability to hear high frequencies as a child. Background - As people get older, their capability to hear degrades whereas younger people like children, have a much better hearing since adults have experienced loud noises throughout their lives which degrades their hearing a little. The…

Sound is an everyday occurring phenomenon, and sounds are continuously happening in nearly all aspects of ordinary life. In order to for our ears to perceive sound, a number of processes must occur, during which sound energy is converted into mechanical energy (NIDCD, 2013). The outer ear collects the sound; the middle ear transforms the energy of the sound wave into vibrations, and the inner ear then transforms this energy into nerve impulses, which eventually reach the brain (The Human Ear,…
