Ear

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, 1996). Sounds are made from the molecules in the air…

gifts from God to the oppressed and shunned. Deafness consists for two reasons; conductive hearing loss and sensorineural hearing loss. Conductive hearing loss occurs when sounds cannot make it to the inner ear, sensorineural hearing loss take place when the cells or nerves in the inner ear cannot receive or transfer sounds to the individual (Atkin). Both types can be present at birth or develop throughout one’s life. History proves that the deaf community can confront many barriers…

structures of the ear comprises of the external ear, the center ear and the inward ear. During the time spent listening to misfortune there is a winding formed bone in the inward ear called the cochlea, which is lined with little hair cells. Sound waves are transmitted by the external ear, through the center ear, to the internal ear. In the internal ear, the sound wave weight moves the hair cells, which then send messages to the mind, through the sensory system, about the sounds heard by the…

one that’s right for you: 1. When purchasing a ballistic helmet, the top of your head should touch the crown pad 2. Check that the helmet is level from front to back 3. Count the number of pads. There should be 7. 4. The portion of your ear at and above the ear canal must be covered 5. Check the pads for tears and compressibility 6. Check for frayed or loose stitching on the…

permissible noise exposure levels. This helpful chart shows exposure levels of common equipment and activities (The University of Vermont 2015). See Figure 1. Typically, sounds in the range of 85-105 dB cause metabolic and chemical disturbances in the inner ear that might lead to…

Grijalva, a lot of her patients seem to go in because they cannot hear well and it’s all due to occlusion of the middle ear because of ear wax. Although it sounds like an easy fix, I do not know if I would be comfortable with the sight of an ear canal full of cerumen and cu tip fibers. Her suggestion for this problem is to tell her patients not to use cu tips to clean their ears since they actually do the opposite of that, they only help push back the cerumen instead of cleaning it out. Talking…

When there are sound wave get into the ear, the sound wave then will pass through the canal to the eardrum. At the eardrum, the sound wave are mechanically transmitted to the inner ear and amplified. In the inner ear there will be a cochlear where this cochlear consist of three different canals. At the middle canal of the cochlear is the organ of hearing where this part consist…

cochlear implant? If so, you may be eligible for social security benefits, if you meet certain requirements. A cochlear implant is a device used to aid in the function of the inner ear by sending signals to the brain. In situations where the inner ear is damaged this electronic device actually replaces the function of the inner ear, giving patients a better chance to hear and communicate with others. The cochlear implant is intended for those who are considered profoundly deaf. The implant…

sound as the ear drums move from the sound pressure. Then, this vibration is transformed into electrical impulses, which are sent to the brain. The transformation of the electrical impulse occurs inside the outer, the middle and the inner parts of the ears. The outer ear is called the external sound-gathering part of the ear. Its function is to gather sound energy and focuses it on the eardrum. The middle ear, an air-filled chamber serves as an amplifier of vibration. The inner ear is where the…

little muffled due to my luxurious ears. I hear them walking down the hallway now, and I hear the sound of my leash jingling in my mom’s hand. We are walking down the side of the road now, and I hear all sorts of animals scattering in the leaves and trees. I love listening to these beautiful sounds, I wish my parents could hear as wonderfully as I can. It’s not as great as you would imagine though, you think that all these cars are loud up close and make your ears ring, but they are 2 to 4…
