Outer ear

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 U.S department of health and Human services further explain that when a noise/sound/frequency is heard, the parts of the ear (inner, middle and outer ear) all play a role in translating sound so we can hear things. Sounds are caused by vibrations in the…

Paelo Manalo Dr. Aida Metzenberg BIOL 241 April 3, 2016 Hear Them Out The first few weeks of pregnancy are the most critical time any complications that can happen to the embryo; most birth defects occur during this time frame. Anotia and Microtia (AM) are birth defects diagnosed when a baby is born. Anotia and Microtia are almost similar diseases. The treatment depends on the severity of the disease and how the ear is formed. The diagnosis for the disease is noticeable at birth however the…

hearing loss in his ear, which occurs when part of the human’s ear system is damaged or doesn’t function properly. it could be noticed when the person is asking everyone to speak slowly and loudly, keep turning the volume of the television and radio up, and will end up avoiding social communications and events. There are three main types of deafness; Conductive deafness is a condition where there is a malfunction in the middle ear (either the ear canal is absent or not open at birth), it starts…

stress inevitable. Interestingly, the ear massage has been proven to be quite effective when it comes to treating various ailments. An ear massage is an easy task which you can perform at the comfort of your home or office. This is a technique that should be done daily so as to provide efficient results in the long-run. Moreover, there are different massage therapies to treat medical conditions that are largely associated with the ear massage. This is why the ear massage should not be…

that travel into the ear, cause vibrations that pass through to the inner ear, and then sent to the brain. Humans…

out from a loud object in all directions and that energy keeps moving through the air until it reaches your ears. That is when you then hear the noise of said loud object. The pinnae (the large outer flaps of your ears), gather all sounds coming from the different directions, they are shaped in a way that allows this. They then go on to channel the energy through into the ear canal. At the end of this ear canal is the eardrum. When the energy, also known as sound waves, hit the eardrum, they…

How does sound travel through the three parts of the ear? There are three parts of the ear in which sound must travel; the outer, middle, and inner ear. Sound does not simply go from the outer ear to the inner ear; it must become four different types of energy in order to pass through. These types of energy are acoustic, mechanical, hydraulic, and electrical. Ears work in a pair to help us localize and discriminate where sounds are coming from in our surroundings. It seems hard to believe but…

An indication that Lucas has an ear infection is that he’s not sleeping well, he hardly eats, and constantly pulling his ear. In children it might be harder to conclude what these symptoms can be exactly since they don’t really speak clearly to actually express what’s bothering them. Chronic otitis media is an inflammation or infection that lies behind the eardrum, it appears and disappears that’s why it’s considered chronic. Some symptoms of otitis media are: sleeplessness, ear pain which…

communicate over long distance in similar ways, but of course have differences since they evolved from different ancestors. Specific to this paper, elephants and whales are discussed; the way their ears, external or internal, are structures and how each section of their ears function to aid in the process of hearing frequencies from conspecifics. Elephants not only use their large ears to capture frequencies of sound, but they also use fatty cushions in the feet pads to detect vibrations by…

This is very similar to the way an inkjet printer sprays ink onto paper. Once the first layer is sprayed, the 3-D printer merely squirts whatever material it is using into more and more layers until the object is complete. It’s remarkable how far the medical field has come since the days of bloodletting and common pneumonia deaths. However, despite the advances that have been made to create modern medicine, there are still areas where technology simply has not kept up with the needs of the…
