Eardrum Essays

The ear has external, middle, and inner portions. The outer ear is called the pinna and is made of ridged cartilage covered by skin. Sound funnels through the pinna into the external auditory canal, a short tube that at the eardrum (tympanic membrane). Sound causes the eardrum and its tiny attached bones in the middle portion of the ear to vibrate, and the vibrations are conducted to the nearby cochlea. The spiral-shaped cochlea is part of the inner ear; it transforms sound into nerve impulses that

Perforated Eardrum The eardrum is a thin membrane found inside the ear, which detects sound vibrations and helps transmit them to the brain. It also plays an important role in protecting the inner ear from bacteria and other foreign objects. A perforated eardrum (or perforated ear drum) occurs when this membrane is torn or damaged, leading to reduced hearing and possible ear infection. Symptoms of a burst eardrum must not be ignored and medical attention must be sought to protect your hearing and

Hearing loss is not always a genetic disease. Causes of deafness can rapidly (ly) travel (v) from ear infections, trauma, loud noise, some medication, birth defects, heredity, and aging. In this paper I will be discussing a few of these types of these causes. [3] Unfortunately hearing loss affects young and old people and even dogs. [2] Concerning pets, I have learned that these diseases can affect pets too. [6] Hearing loss is imperfect (adj). Hearing loss at birth is called congenital

order to prevent damage to the eardrum. The outer ear also channels sound waves that reach the ear through the ear canal to the eardrum of the middle ear. Because of the length of the ear canal, it is capable of amplifying sounds with frequencies of approximately 3000 Hz. As sound travels through the outer ear, the sound is still in the form of a pressure wave, with an alternating pattern of high and low pressure regions. It is not until the sound reaches the eardrum at the interface of the outer

speaker is. Curious yet? I will teach you about these 2 main topics, how sound works, and how speakers work. Speakers create sound waves, but what is sound? Inside the ear, there is a thin cone-shaped membrane called the eardrum (encyclopedia britannica n.d.) When the eardrum vibrates, your brain translates it to a sound (Harris, Tom 2001). The most common vibration is rapid changes in air pressure. Sound is created when an object vibrates in the air. The air particles around the object moves, and

Ear Infection in Babies Symptoms The easiest way to tell if there is ear infection in babies (or any other illness) is by observing a change in his mood. If the baby starts crying more than usual, then be on the lookout for any problem. If he also develops a fever (slight or high), you have a bigger clue. Ear infections also follows a common cold or even a sinus infection, so keep that in mind also. You might also notice the below indicated symptoms: • Your baby pulls, or tugs at his ears. This might

Did you know that horror filmmakers use infrared sound to induce anxiety, sorrow, and heart palpitations? How do they achieve this effect you might ask? Well this is mostly due to a lesser known field of science called psychoacoustics, the study of audiology and sound perception. Although you may not realize it now, psychoacoustics actually affects most people in their day to day lives, whether it’s via music listening or watching a movie, you’re almost always subject to the effects of psychoacoustics

drugs before I was born and during her pregnancy. Therefore, I was born without an eardrum. My mother did not pay much attention to me, so it went unnoticed until I started third grade. Surgery was scheduled the following summer to build a new eardrum. Prior to the surgery, I spent the first few years learning to read the teachers lips and studying at home. Even though surgery went well, later in life the new eardrum they created would not hold and it deteriorated. Throughout my life, I never thought

a) The common cold Common cold is simply known as a cold, is a viral diseases that affects the upper respiratory tract primarily the nose. Common cold also affect the sinuses, bronchial tubes and the ear. Colds usually last for about a week. Mild colds can last up to three days whereas severe colds can last up to two weeks. Colds are caused by viruses. More than 200 different viruses can cause a cold. There are two groups of viruses, rhinoviruses and coronaviruses. These are the two very common virus

directions; he could not breathe, there were iron bands tightening around his cheat; his eyeballs were being forced back into his head; his eardrums were being pushed deeper into his skull” (60). In this sentence, the author exaggerates the feeling of Harry that “iron bands tightening around his cheat”, “his eyeballs were being forced back into his head”, and “his eardrums were being pushed deeper into his skull”. These physical actions is impossible happen on Harry, but the author writes in this way can

in this passage. There was a sharp smell of alcohol. A clank as the ear doctor opened his sterilizer. I saw the needle in his hand it looked as long as a ruler in my school pencil box and tensed…. He slid the needle in my ear and punctured my eardrum with it. The pain was beyond anything I have ever felt since...” (King 11). This use of imagery, in this case, is used to make the audience sympathetic towards young Stephen, but at the same time it is used to put the reader in his place. This

Part one, the transmitter and part two the receiver. The Transmitter of a telephone, lies behind the mouthpiece of the phone. Like the human ear, the transmitter has an 14 eardrum. The eardrum of the telephone is a thin, round metal disk called a diaphragm. When a person talks into the telephone, the sound waves strike the diaphragm and makes it vibrate. Behind the diaphragm lies a small cup filled with tiny grains of carbon. The

Ears Popping When Swallowing Are your ears popping when swallowing? This may be an annoying problem, but it is usually not a serious one. Unless you have actually damaged your eardrums due to barotrauma, then ear popping may just be due to your body trying to relieve pressure in your ears when you swallow or yawn. You see, sometimes, there is a pressure difference between the outside of your ear drum and the eustachian tube inside. This phenomenon occurs when you are flying or climbing high altitudes

Earwax - yes, ear wax is a sign of healthy ears What is earwax and why is it so important? Have you ever wondered why the formation of earwax in the ear, ear wax and what actually is? We have collected some of the facts that will teach you more about earwax. Ear wax is a mixture of liquids formed by glands on the outside of the ear canal. These liquids mixed with dust and dead skin cells to form it as you get up when you clean your ears. Earwax has three important functions for your ears: -Earwax

In the animal kingdom, a species’ sole goal of existence is to survive and pass on its genes through reproduction and further populate the planet with it’s own kind. The act of mating between a male and female is how most species biologically create life and it’s pivotal to ensure their own species will continue existence. How two animals from the same species mate is as unique as each individual. With there being millions of different organisms on one planet, this creates millions of different ways

A CT scan, CT standing for computed tomography, uses X-Rays from many different angels to make a detailed picture of the structures inside the body. It allows doctors to see what is happening inside the body without having to cut somebody open. A CT scan is taken in a donut shaped ring and a bed, the bed gets rolled into the scanner. An MRI, standing for magnetic resonance imagining, use strong magnetic fields to make photos of the organs in a person's body without cutting the body open. An MRI

build up from various ear infections I’ve had tubes put in and taken out too many times to count. After twenty ear related surgeries,one of which being a skin graft to reconstruct my left eardrum after it didn’t heal on its own once the tubes were removed, I gave up counting. Due to the reconstruction of the eardrum and the large amount of scarring from tubes, I now have permanent conductive hearing loss on top of the temporary conductive hearing loss due to occasional excess wax during bad infections

When I was born I was missing a nerve that connected my right eardrum to my brain. I have no hearing on my right side. I am half deaf. It is hard for me to hear what people are saying, and also understand it. As i grew older i told my friends and classmates about it. At first they did not believe that I was half deaf. Because of their doubt, people were always whispering in my bad ear. After they did so, they would look at me expectantly. I just stare back with a blank face. Now that i have gotten

Malala Yousafzai was only 16 years old when she was shot for speaking up for the 31 million girls around the world who cannot get an education. Yousafzai was shot October 9, 2012. A famous saying of hers was, “Let us pick up our books and our pens, they are the most powerful weapons.” A men approached the bus Yousafzai was riding in and asked, “Who is Malala?” After that she did not seem to remember what happened next, however her friend described the scene. Two hours had passed until a helicopter

Rudy shows us that he is a hateful man. In 1942, he was beaten up by four policemen while running around as a zoot-suiter in his teens. He was left with a fractured eardrum and couldn’t hear from both ears. His Uncle Abraham told him, “That to hate is to waste energy and you mess with man upstairs” (Smith 3). Rudy says, “But I had an insane hatred for white policemen” (Smith 3). After being beaten up by the white police officers, he developed his hate towards the policemen even though he doesn’t
