Auditory system

I haven’t realized that the mechanism for us to hear the music is quite different from the languages before. This video reminds me of one of my classmate in middle school, who is born deaf and had the cochlear implant. He could communicate with us but his pronunciation is slightly different from us. It happened almost ten years ago and I am not sure whether the cochlear implant devices have been greatly improved nowadays. According to the video, the modern multi-channel cochlear implant device…

Diseases Affecting the Ears Objective It is universally acknowledge that hearing is not an essential part of communication. Many people are able to communicate and function well in society without difficulty with this impairment. Those who are deaf are able to communicate in sign language. We are able to hear sound thanks to the structure of our ear. Although infants cannot make sense of the meaning of the sound, they hear from their surroundings, they are able to hear them, and later, make…

Introduction The authors first point is that early detection compresses the decision-making process. They argue that because of the mandate, doctors are now the first ones to suspect that a child may or may not be deaf, and this can cause issues because the family is particularly vulnerable to this information which can lead to the parents feeling like they need to make a decision now. This is not conducive for the parents to make rational well-informed decisions. The author argues that the…

Researchers are having a hard time of gathering statistics in the United States on the disease because of its severity ranging from mild to severe. Due to this problem, researchers have been using birth defects tracking systems to gather some results. The system has estimated from less than 1 in 10,000 live births for Microtia, type 1 to type 3, to 5 in 10,000 live births for Anotia. In the 80’s a lot of researchers were trying to figure out if the birth defect is a genetic disease or a…

I want to first start off by saying this was a hearing person that talked about the functions of what an audiogram does. I observed a guested speaker who talked about the audiogram. She gave us information about what audiogram and what she does. An audiogram is a graph that shows the audible threshold for standardized frequencies as measured by an audiometer which as a Y and X axis. The Y axis represents intensity measured by decibels and the X represents the frequency by hertz. The threshold of…

A small clump of hair was recovered from a murder victim who was holding onto the clump of hair. The first step is to determine the color, length, and diameter of the hair found. The shape and color intensity of pigment granules can be different if the hair has been dyed or bleached. Dyed hair has color in the cuticle and cortex; bleaching removes pigment and gives a yellow tint. Then, determine if the hair found is human hair or animal hair by checking the cuticle scale patterns. There are 3…

Misophonia is a brain disorder in which a trigger sound can send a person into extensive irritation or —in extreme cases—even rage. Symptoms typically present themselves in children from the ages of 9 to 13, but it can show both earlier and later in life. Affecting millions of people in the world, misophonia is extremely common and nearly undetectable in most cases. People who have very mild cases often times never go diagnosed; however, it does not usually have a large impact on their everyday…

In the past few years, stories and cases of hearing loss became more and more often. “How and why is this happening?” was the question racing through the minds of people worriedly. Upon hearing this trendy topic, author Jennifer Dignan wrote an article named “Throw Away Your earbuds Now!”, and claims that the reason for hearing loss is answered in this article. This essay is focused and centralized on the subject of how she supports her postulate that the answer to this question is not only in…

Distractions are all around us, and often they can send our head spinning. But is there a possibility much like when a person gets paroxysmal positional vertigo, that all these distractions could throw us off the pathway leading to Christ? In our inner ear we have two labyrinths First the Static labyrinth, which consists of the utricle and Saccule. Second, we have the dynamic labyrinth which consists of three semicircular canals, in this section of our ear there are little hairs called…

Ear surgery, also called otoplasty, helps to improve the shape, position or proportion of the ear. Otoplasty also corrects any defects in the structure of the ear that can be from a birth defect, happen during the body’s development, or from an injury. Ear surgery creates a more natural-looking appearance to the shape of the ear, while improving the balance and proportion of the ears in relationship to the face. Even minor deformities, when reshaped, can have deep-seated, positive bene?ts to…
