People find the whole idea of ear stretching to be gross and pointless. Ear stretching is not understood by older generations because of the terminology used when referring to ear stretching, the process of getting them to a specific size, and the whole idea of someone wanting to have giant holes in their ears. Older generations cannot seem to wrap their…

plotted by the curve that is normal hearing in dB (HL). She then went on to tell us that audiometer is a devise that helps to tell how good your hearing really is by putting on headphones and then making sounds in different level on both sides of the ears, and you have to put your hand up if you can hear them. On the headphone there are marks with two different colors the right is red and the left is blue when you hear the sound you are to raise your hand to indicate that you can hear the…

Conjunctiva: It is a mucous membrane which covers the under surface of the eye lids and is reflected form the eyelids to cover the anterior part of the eyeball up to the margin of the cornea.

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 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. For profoundly deaf people may possible communicate by lip reading and sign language. This disorder occurs when the inner ear or auditory…

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…
