Results The purpose of this research was to illustrate and compare the differences in shapes of auditory filters of two individuals. The signal to noise ratio (P/N0) represented in Table 1, is a ratio of the power in the signal (P) over the spectrum level of noise (N0) which remained at 35 decibels except in the notch. The P/N0 is given in decibels and is derived by multiplying the log of this ratio by 20. Figure 1 displays the relationship between these variables and the width of the notch (f/fΔ) for both participants in the study. The figures indicate that as the P/N0 decreases the f/fΔ increase in a very similar trend for both participants in the study. While this trend was seen in both…

The earliest of studies for speech sounds has been studied intensively since the early 1930s. Studies concerning the acquisition of phonemes are used in clinical practice and serve as a guideline to a practicing clinician. The earliest of studies came from 1931 by Wellman, Case, Mengert and Bradbury. Following Wellman’s findings, other researchers found new material and listing different ages in comparison to Wellman’s research. Sander (1972) discusses the various individuals that contributed to…

The experimenters followed their experimentation with analysis of the data obtained. The experimenters first contemplated the applicability of the Probe Comp test signal to biological systems. The experimenters reasoned that the test signal was not an effective description of a biological system because the test signal did not exhibit the noise present in biological systems. While considering the observations of the oscilloscope and biological systems, the experimenters considered which settings…

COME 582-Cellular Communications Assignment 1 Due Monday October 17, in class Notes: You MUST work individually on the assignment. Piazza can be used to ask questions (without requesting a solution) !! Try to work on as many questions as possible. Grade will mostly be based on the effort spent. Problem 1 Cellular Architecture Consider a city of 10 square kilometers. A macrocellular system design divides the city up into square cells of 1 square kilometer, where each cell can accommodate 100…

opposed to Mozart (2007). Combining factors, McDonald (2013) found that participants with higher levels of extraversion performed better in the presence of preferred music than in the presence of silence or pre-selected music. Decibel differences could have contributed to the discrepancies between the hypotheses (R. Rams, personal communication, January 14, 2016). Decibels, a measure of sound, are measured on a logarithmic scale; therefore, a small change in the number of decibels would greatly…

Hearing is measured in decibels, which measures the intensity of sound. When measuring a person’s hearing ability, hearing loss is recorded when the person cannot hear a sound lower than twenty-six decibels. In comparison, profound hearing loss is described when a person cannot hear a sound lower than ninety-five decibels (Clason). According to the Hearing Loss Association of America, twenty percent of Americans, which translates into forty-eight million people have some degree of hearing loss…

healed and is very common, but it may not be the only contributor to your hearing loss. “"I have an audiologist friend at Wichita State University who actually pulls off earphones of students he sees and asks, in the interest of science, if he could measure the output of the signal going into their heads,"...Often he finds students listening at 110 to 120 decibels.” (Baessler) When you are listening to music with headphones or earbuds, it is very easy to not notice how loud the music is. For…

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…

Making the boxes was easily the hardest task physically of this assignment. Each box was chosen for a different reason, for example, the hard foam box was the one that was thought to do the best, due to the air pockets and likeness to a yoga mat but much cheaper and easier to source. There was also the Blanket, this was kind of like a control except we lined it with blankets as they are easy and cheap, and knew that it would somewhat muffle the sound waves from escaping. Styrofoam was one that…

action over time. A wavelength can be measured by trough to trough, or crest to crest. For example, if there is two wavelengths in a single wave, since they repeat and are similar in many ways, the first wavelength’s distance can be measured by taking any point on the first wavelength and measuring the distance until that same point s reached on the corresponding wave. Another pattern of sound is known as a “decibel”, which is the intensity of a sound. The “decibel scale” determines the…
