Introduction The acoustic reflex (AR) describes the involuntary contraction of the stapedius tendon in response to high-intensity sound (Emanuel, 2009). An intricate neural network, receiving afferent input from the vestibulocochlear nerve and sending efferent output to the facial nerve, controls contraction (Emanuel, 2009). The reflex is intensity-dependent, as particular intensities cause the contraction. Once contracted, it lessens the vibrations traveling through the stapes footplate as it…
efficiently in a manner in which the patient will understand more completely. After the education session time needs to be set aside for the patient to ask any answers that they may have or not understand. The patient must feel comfortable with the responses to the questions from the nurse that they have asked so they will be ready for the process of choosing and the knowledge required for safe usage of their new hearing…
vision. The setting seems peaceful which connects the viewer of being relaxed and drawn into it. The auditory cue used in this advertisement is a subtle rock-n-roll song which relates to the middle-aged man. Since this is all tied together and our perception makes sense of it, it reaches our expectation values (subconscious). The list of side effects that the voice stated, which is also an auditory cue, makes me continuously aware of the increases in health risks of anyone taking the…
When we look around us we do not even think about it, we check both ways before crossing the street, we admire the sunset early in the morning, or we read a book. But, we never think about how we see things, how does what we see get translated into things that we can understand? It starts in the retina, where the receptor cells are. There are two types of receptor cells, rods and cones, both are only sensitive to visible light. Rods are chiefly responsible for night vision and respond to only…
also known as nerve deafness. Normally, the vibrations from the middle ear create waves in the fluid inside the cochlea. The waves in turn stimulate thousands of delicate hair cells that line the cochlea. Their movement makes nerve impulses in the auditory nerve, which lies just beyond the cochlea and carries the impulses to the…
incorporating all all three learning domains (visual, auditory and kinesthetic) within the instruction period, and as a reinforcement tool during student’s practice/ on task time. Pre assessment results underline and further back this fact, based upon the fact that the skill was introduced only through visual cue giving. Auditory cues revealed to be most effective when accompanied as an aid with visual or kinesthetic cues. Even as a non auditory learner it is a reminder, a reference…
Unfortunately, I was unable to observe a science lesson at my field placement because at the time science wasn’t taught. Instead I evaluated a science lesson form You-Tube for first grade. In the lesson, students learned about the beginning stage of a sound wave. The teacher mainly focused on the eardrum. Students learned through questioning, experimentation, and class discussions. After reviewing the lesson, I have concluded that I think it is effective in teaching students about sound waves…
Noise can cause permanent hearing loss at chronic exposure levels of at least 85 dB or higher for an eight hour period (Peter M. Rabinowitz, Pg.1). The louder the sound, the shorter the time period before NIHL can occur. Sounds of less than 75 decibels, even after long exposure, are unlikely to cause hearing loss (Hearing Health Foundation 2015). Hearing loss that is caused by the noise exposure due to recreational or non-occupational activities is termed socioacusis. Hearing loss due to…
The Noisy Pollutant It 's Saturday morning at 6 AM and you can hear the planter outside blowing leaves and trimming the hedges. Trust it or not, you have recently been victimized person to commotion contamination, and your wellbeing perhaps enduring in view of it. Commotion Pollution is not just an irritation; it is an ecological wellbeing peril. Commotion can be discovered anyplace that life exists, in woods, in the working environment, in homes crosswise over America and even submerged. A…
Observations: On December 6, 2016, Temple University Speech Language and Hearing Center (TUSLHC) offered free hearing screenings to Temple University faculty and students. Three screenings were observed. Each screening included a throughout case history interview, an otoscopic examination, and pure-tone threshold hearing screening. During the case history interviews, the graduate clinicians asked each client a series of questions pertinent to their hearing. The case history included questions,…
