Auditory masking

I want to first start off by saying this was a hearing person that talked about the functions of what an audiogram does. I observed a guested speaker who talked about the audiogram. She gave us information about what audiogram and what she does. An audiogram is a graph that shows the audible threshold for standardized frequencies as measured by an audiometer which as a Y and X axis. The Y axis represents intensity measured by decibels and the X represents the frequency by hertz. The threshold of…

A small clump of hair was recovered from a murder victim who was holding onto the clump of hair. The first step is to determine the color, length, and diameter of the hair found. The shape and color intensity of pigment granules can be different if the hair has been dyed or bleached. Dyed hair has color in the cuticle and cortex; bleaching removes pigment and gives a yellow tint. Then, determine if the hair found is human hair or animal hair by checking the cuticle scale patterns. There are 3…

Misophonia is a brain disorder in which a trigger sound can send a person into extensive irritation or —in extreme cases—even rage. Symptoms typically present themselves in children from the ages of 9 to 13, but it can show both earlier and later in life. Affecting millions of people in the world, misophonia is extremely common and nearly undetectable in most cases. People who have very mild cases often times never go diagnosed; however, it does not usually have a large impact on their everyday…

In the past few years, stories and cases of hearing loss became more and more often. “How and why is this happening?” was the question racing through the minds of people worriedly. 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…

Distractions are all around us, and often they can send our head spinning. But is there a possibility much 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…

The eardrum further vibrates the hammer, anvil, and stirrup. The stirrup vibrations cause the oval window to vibrate which causes the fluid in the cochlea to vibrate. The fluid bends the hair cells which then send signals to the brain through the auditory nerve. The brain receives the signals and processes the information that allows people to hear sounds. All of the parts of the ear are held responsible for people to…

becoming a hearing screening and further my interest in audiology. Firstly, as a Newborn Hearing Screener, I perform newborn hearing test on newborns within the first 24 to 48 hours of birth. The test procedure that is used is an Automated ABR (Auditory Brainstem Response) that measures the brain nerve responds to sound. A click sound…

Ear surgery, also called otoplasty, helps to improve the shape, position or proportion of the ear. Otoplasty also corrects any defects in the structure of the ear that can be from a birth defect, happen during the body’s development, or from an injury. Ear surgery creates a more natural-looking appearance to the shape of the ear, while improving the balance and proportion of the ears in relationship to the face. Even minor deformities, when reshaped, can have deep-seated, positive bene?ts to…

Hearing loss in teenagers is up 30 percent from the 1980s and 1990s. While in-ear headphones were first introduced in the 1980s, they didn’t become widely popular until the early 2000s when the iPod came out. “Many experts believe it [increased percent of hearing loss] is due... to the increased use in headphones” (American Osteopathic Association). This is a plausible explanation seeing as music seems to be more available and used more often. Hearing loss due to exposure is a growing concern.…

There are unique auditory processes that are very important to help the listener deal with simultaneous, often competing audio signals or sources such as competing speakers or musical instruments/instrumental sections within an orchestra. To be able to distinguish the individual sounds and more importantly, the individual superimposed vibrations travelling to the listener, the auditory system, and the architecturally designed environments, have specific methods that allow the listeners ears to…
