patients lungs and heart before the stethoscope was invented? How they made accurate diagnosis without the essential stethoscope all healthcare workers use today? Before the early 1800’s physicians didn’t have a tool to do this. They would place their ear next to the patient's chest and back to hear the sounds of the body specifically the heart and lungs. The creation of the stethoscope changed the way physicians performed examinations, listened, diagnosed, and treated patients. The definition…

children is the condition otitis media with effusion, or also known as glue ear. Hearing loss typically occurs in part of the outer ear if it is congested. This then causes the sound waves incapable of reaching the middle or inner section of the ear. A conductive hearing loss can transpire in the outer or middle ear region containing poor conduction of sound along the channels leading primarily to the inner part of the ear. Due to this, sound is not focused well and is spread in a weaker and…

Sound travels through matter, which is a solid, liquid or gas. Sound travels in longitudinal waves. There is also a vibration that starts on an object, and this causes a vibration on all the molecules. When these molecules vibrate, they cause all of the other surrounding molecules to vibrate. This vibration will spread from molecule to molecule causing sound to travel. 1. What is a wave? A wave is a chain of vibrating molecules. In general, a wave transfers energy from one place to another. 2.…

early life, whereas [hearing loss] was found to be related.” The only certain reason that a child’s language would continue to be affected by otitis media past early childhood is if the middle ear problems persist as the child grows. In these children, reading will still be impaired as long as the middle ear…

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…

also known as central auditory processing disorder (CAPD) is a Phonology language condition where the child is having difficulties differentiating different sounds. The child has difficulties processing what they hear because their brains and their ears don’t synchronize properly. The child usually has normal hearing but struggles with sounds, particular if there are other noises in the background. The main issue is that the child has problems understanding the sound of what he is hearing, not…

vibrations traveling through the stapes footplate as it pulls the stapes away from the oval window, decreasing the energy to the cochlea and compliance (Emanuel, 2009). Furthermore, it is a bilateral phenomenon as stimulation in one ear evokes an AR in the opposite ear as well, involving contralateral and…

My voice has always been a powerful part of my existence. I can shout when my soul has been shattered by wrong doers. My opinions have never been stifled by fear of hearing myself stand upon my convictions. I’m not shy, reserved, nor is my back adorned with a “welcome mat” to be walked upon. The very fiber of my being disregards feminist that have struggled for me to be heard. I choose my voice to be silenced. Unfortunately, embedded in my heart is a missed opportunity to educate an ignorant…

thing I can hear is the busy chit chat of foreigners and the clicking of all of the suitcases. It reminds me of a clock ticking in my ear; a clock that’s telling me “it’s almost time”. I walk up to my Dad and hug him, I smell his intense cologne off of his shirt; Im looking at him and he’s talking to me but everything is muffled as if someone shoved cotton in my ears.
