The eye is one of the significant special sensory organs that is responsible for vision. Through observation, we handled a cow’s eye and discerned our findings to our knowledge of a human’s eye. A cow’s eye has similarities, such as the overall layers of the eye like the sclera, choroid, and retina layer, to that of a human’s eye. Also the structures and organs contained within these layers. Also, we discovered many other anatomical structures that are much the same to a human's eye during the…

Pop filters When recording vocalists, you will most definitely need to place a pop filter between the singer and vocal mic. A pop filter will cut down on the mini-explosions of air that happen when a singer says “B” or “P”. Don’t ever leave this job for a compressor down the line. Pop filters also serve the secret purpose of blocking all spit spray from reaching your prized vocal mic. It is not uncommon to find studios stacking two pop filters depending on the singers style. Here are a couple of…

you to consider. To clarify some of your questions, the abbreviation of dB stands for decibels, which is how acoustic power is measured. Since the human ear can’t hear all the sounds that may be measured by a sound level meter or dosimeter, we will often add weighting, called A-weighting, to relate the results more accurately to the human ear. When dBs are averaged among the hours of an employee’s 8-hour workday, we call it the 8-hour time-weighted average. We can also calculate a time-weighted…

wax blocking the ear canals. Hearing loss can have all different stages of how bad it is. People who have a hard time following speech would be considered mild hearing loss. Moderate deafness would be difficulty following speech without a hearing aid. People who rely on lip reading when even having a hearing aid it would be considered severely deaf.

What did they measure? They measured the relationship between cognitive decline and hearing loss over time. c. How did they form their groups at baseline? Baseline for this study was a “cohort consisted of participants without prevalent cognitive impairment who underwent audiometric testing…

In this passage, Julian Henriques, the author of Sonic Bodies: Reggae Sound Systems, Performance Techniques, and Ways of Knowing, main idea was to open the reader’s mind to the fact that there are several different forms of sound that can be taken into different contexts. He describes how sound effects not only your auditory system, but the other senses as well. Your body becomes a part of the sound such as you can feel the vibrations within your cells from the music or sound. No matter what you…

intermittent rustling of paper. These sounds are familiar in every classroom across the country and it is very easy to block out noises and concentrate on the task at hand, unless someone were to have misophonia. I was fine in this setting until my traitorous ears pinpointed my trigger noise out of the room. A person without Misophonia would have just dismissed the noise as nothing more than simple classroom sounds that cannot be prevented. I could not help but be annoyed after I isolated a…

Upon hearing this trendy topic, author Jennifer Dignan wrote an article named “Throw Away Your earbuds Now!”, and claims that the reason for hearing loss is answered in this article. This essay is focused and centralized on the subject of how she supports her postulate that the answer to this question is not only in…

like when a person gets paroxysmal positional vertigo, that all these distractions could throw us off the pathway leading to Christ? In our inner ear we have two labyrinths First the Static labyrinth, which consists of the utricle and Saccule. Second, we have the dynamic labyrinth which consists of three semicircular canals, in this section of our ear there are little hairs called stereocilia, on top of the hairs we have a liquid called cupola. When the cupola moves across the stereocilia it…
