Hearing allows us to do our everyday activities and improves our lives. It enables us to communicate, socialize, and interact in our environment. Good hearing also helps to keep us safe, warning us of dangers or alerting us to someone else’s distress. Hearing is necessary for us to be able to participate in life more fully. Our hearing provides us with a huge source of information; some of it is known to us and some we don’t even notice but when combined, this information gives us the opportunity to be aware and interact in our world. Hearing helps us live our everyday lives without limitations. Some everyday situations where are hearing is important are at work, at social occasions, learning, and for our own safety.
Our ears are intricate pieces of work and there is a lot to the anatomy and physiology of how the ear. The visible or external part of the ear has more of an action like funnel, amplifying sound waves to be captured and easily directed in the ear canal. The Pinna has an interesting role allowing the canal to receive low sound frequencies by reflecting off of the Pinna. The interesting observation about the Pinna is that not only does it act as a reflector for low frequency but acts as a filter for High frequencies to not destroy the ear drum. (http://en.wikipedia.org/wiki/Pinna_(anatomy))
The Tragus is the small piece of skin that covers the ear canal. Its name came from the Greek term of a goat because of the hair that grows off of it resembled a goat’s beard. The hair off of this does have a use though as it collects sound from behind. Below the tragus is the Ear Lobe which does not have any major function for the body but it is the area that people pierce to have earrings. Sometime people have allergic reaction...

Hearing allows us to take in noises from the surrounding environment and gives us a sense of where things are in relation to us. All those little folds on the outside of the ear, called the tonotopic organization, make it so sound waves in the air are directed to the ear canal, where they can be further processed. Once in the ear, the sound waves vibrate the ear drum, which tell the ear exactly what frequency it is sensing. The vibration of the ear drum is not quite enough to send a signal to the brain, so it needs to be amplified, which is where the three tiny bones in the ear come into play. The malleus or hammer, incus or anvil, and stapes or stirrup amplify this sound and send it to the cochlea. The cochlea conducts the sound signal through a fluid with a higher inertia than air, so this is why the signal from the ear drum needs to be amplified. It is much harder to move the fluid than it is to move the air. The cochlea basically takes these physical vibrations and turns them into electrical impulses that can be sent to the brain. This is...
There are many everyday devises that we hearing people take for granted, among these are telephones, smoke alarms, doorbells, and alarm clocks. When we look at how members of the deaf community use these everyday items we must consider that members within the community have very different communication needs, abilities, and preferences. Hard-of-hearing people for example can use a standard telephone with the addition of a headset or amplifier, while some hard-of-hearing people may prefer a TTY deaf persons rely on it, or a relay service to communicate as we (hearing people) would on a telephone.
First, one must understand the distinction between hearing and listening. Hearing is simply the reception of sound waves by the ears. This may happen unconsciously, as is usually the case with soft background noise such as the whoosh of air through heating ducts or the distant murmur of an electric clothes dryer. Sometimes hearing is done semi-consciously; for instance, the roar of a piece of construction equipment might momentarily draw one's attention. Conscious hearing, or listening, involves a nearly full degree of mental concentration. A familiar i...
I carried out the exercise while I was in school. I am an office aid, so I have multiple encounters with people both on the phone and in person. I felt that this would be an ideal situation in order to simulate an accurate experience someone with hearing loss. As my day began, I sat in a calculus class with my other classmates. I found it very difficult to understand what the professor was saying, especially because there were people talking all around me. The following period is when I am an office aid, and at the beginning of the period I answered multiple phone calls. Throughout these discussions, I had to repeditly ask the person on the other end of the phone to repeat themselves or speak louder. I became frustrated because I still could not hear them clearly, so I transferred them to the secretary’s desk so she could answer their
Most people are familiar with the word "music", however they barely consider the definition of it. After carefully think, everyone has their own opinions on this term and it is hard to have an uniform criterion of music sounds. According to the text book, Michael B. Bakan states five propositions to define the music. The first one is about the tone and the second one talks about the music is organized in some way. The next two are claims that music is human organized and a product of human intention and perception. The last proposition argues music cannot separate from Western culture. Among these propositions, I think the music is a product of human intention and perception is most interesting and worth to discuss. So I assert that the most
Especially for infants and children, loss of hearing at such a young age can be detrimental for a developing child (Williams & Jacobs, 2009). The first two years of life are the most important as they hold critical milestones of language acquisition (Zumach, Chenault, Anteunis, and Gerrits, 2011). If these milestones are not met, then the subsequent ones will be harder and take longer to learn. The loss of hearing in young individuals can alter the perception of words and sounds, and this can lead to a difficulty in learning language (Williams & Jacobs, 2009). For example, the child will not be able to determine the difference between similar sounds, which negatively affects speech perception, which then leads to the inability to interpret and acquire language later on (Williams & Jacobs,
Specific Purpose: To help people to understand what Audism is and that the lack of an ability to hear does not mean they are incapable of performing tasks.
A hearing loss can present many obstacles in one's life. I have faced many issues throughout my life, many of which affected me deeply. When I first realized that I was hearing-impaired, I didn't know what it meant. As I grew older, I came to understand why I was different from everyone. It was hard to like myself or feel good about myself because I was often teased. However, I started to change my attitude and see that wearing hearing aids was no different than people wearing glasses to see.
For any individual who either avidly listens to or performs music, it is understood that many melodies have amazing effects on both our emotions and our perception. To address the effects of music on the brain, it seems most logical to initially map the auditory and neural pathways of sound. In the case of humans, the mechanism responsible for receiving and transmitting sound to the brain are the ears. Briefly stated, the outer ear (or pinna) 'catches' and amplifies sound by funneling it into the ear canal. Interestingly, the outer ear serves only to boost high frequency sound components (1). The resonance provided by the outer ear also serves in amplifying a higher range of frequencies corresponding to the top octave of the piano key board. The air pressure wave travels through the ear canal to ultimately reach and vibrate the timpanic membrane (i.e.-- the eardrum). At this particular juncture, the pressure wave energy of sound is translated into mechanical energy via the middle ear. Here, three small bones, the ossicles, vibrate in succession to produce a unique pattern of movements that embodies the frequencies contained in every sound we are capable of hearing. The middle ear is also an important component in what music we actually keep out of our 'head'. The muscles grasping the ossicles can contract to prevent as much as two thirds of the sound from entering the inner ear. (1, 2)

Living in a world with no sound whatsoever is a reality to millions of people worldwide, regardless of age, race, gender, and socioeconomic status. Approximately 5% or 360 million people of the world’s population have deafness or hearing loss, according to the World Health Organization. Deafness can be either acquired or congenital depending on several factors, including genetics and health of the individual. Congenital deafness is the loss of hearing present at birth. Being born deaf has many consequences, both positive and negative. According to the American Speech-Language Hearing Association, over 50% of congenital deafness is due to hereditary and genetic issues. However, non-genetic factors can cause deafness in an individual at birth as well. Disease and illness while in utero of either the mother or child can cause the child to become deaf...
Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
The External or Outer Ear - comprises of the auricle or pinna which is the fleshy part of the outer ear. It is cup-shaped and collects and amplifies sound waves which then passes along the ear canal to the ear drum or tympanic membrane. The rim of the auricle is called the helix and the inferior portion is called the lobule. The external auditory canal is a carved tube and contains a few hair and ceruminous glands which are specialized sebaceous or oil glands. These secrete ear wax or cerumen. Both the hairs and the cerumen help prevent dust and foreign objects from entering the ear. A number of people produce large amounts of cerumen, and this sometimes cause the build up to be impacted and can bri...
Hearing is known to be an automatic function of the body. According to the dictionary, hearing is, “the faculty or sense by which sound is perceived; the act of perceiving sound,” (“hearing…”). Hearing is a physical and involuntary act; therefore, unless one is born with a specific form of deafness, everyone has the natural ability to hear sounds. Sounds constantly surround us in our everyday environments, and because we are so accustomed to hearing certain sounds we sometimes don’t acknowledge them at all (or “listen” to them). The dictionary definition of listening is, “to give attention with the ear; attend closely for the purpose of hearing,” (“listening…”). This differs from hearing in that this is a voluntary action, and we have control over what we choose to listen to. As stated by William Seiler and Melissa Beall, “You don’t have to work at hearing; it just happens… Listening, on the other hand, is active and requires energy and desire,” (145).
