  • Mastery Of Sounds

    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 concept of mastery of sounds, along with also offering criticism to the findings other researchers. There are misconceptions in the concept of age acquisition. Researchers may use percentages or may have a certain criteria to consider when a child has successfully acquired a sound. Through the use of cross-sectional studies, researchers gathered data on the sounds acquired from a group of children in groups similar in age. In Wellman’s findings, a percentage of 75% or greater was used as a scale in which children produced the consonant accurately (Sander, 1972). Wellman presents the acquisition of sounds ranging from three years of age to 6 years of age. Four consonants are not listed with an age in Wellman’s consonant mastery, the sounds without age are, /θ/, /dʒ/, /ʃ/, /ð/. There was no data recorded for the previously listed sounds. Wellman’s norms served as a foundation for other studies that were later performed. Mastery of a sound is generally defined when a child has…

  • Oscilloscope Response Paper

    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…

  • Noise Induced Hearing Loss Essay

    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…

  • Hearing Observation Paper

    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…

  • The Benefits Of Cochlear Implants

    person takes for granted (FIRST YEARS). Hearing loss can be classified as: normal, mild, moderate, severe, or profound (L. Melnick, personal communication, December 12, 2015). A normal to slight hearing loss falls in between the range of -10 to 25 decibels. From about 26 decibels to about 55 decibels is the range of a mild to moderate hearing loss. 70 decibels to 90 decibels marks severe hearing loss. Anything beyond 90 decibels and classified as a profound hearing loss (L. Melnick, personal…

  • Synophysiology Of Knowing

    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…

  • The Influence Of Music On The Brain

    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…

  • NRC: Noise Reduction Coefficient

    soundproofing materials which can be found at every day home improvement stores will be tested for their abilities to absorb sound at different frequencies. The sound source will be placed in the box and measured externally for sound transmission. The different materials will then be lined along the interior of the box individually and tested for their respective levels of transmission at three different frequencies. This is done because the sound of different frequencies passes through…

  • Music And Hearing Loss

    ways music can harm health. The journals did not mention any other specific ways that music can harm health other than hearing impairment, which makes the argument weaker. They provided evidence and a case study that supported their chosen side of the argument. The main problem with the journal research of Fleming is the research that proved people’s hearing is impaired when listening to music for long periods of time and at certain levels did not specify at what rate hearing would be lost. The…

  • Museum Observation Essay

    the rest of the building I measured the intensity of the sounds in the exhibition rooms, café, restaurant and halls, using an Iphone application called Decibel 10th. The average intensity of the sound in the exhibition rooms was 60 to 63 decibels, which is also the average of a normal conversation. As expected, the café was the loudest with a measure of 73 decibels and as for the halls and the restaurant, both came up at an average of 65 decibels. I took my first measurements on a Thursday…
