Bluetooth Headset Specifications And Its Possible Effects On Hearing Loss, Kristi Ann Anderson

Doctoral Dissertations

The purpose of this study was to determine Bluetooth headset specifications and its potential effects on hearing loss. The following research questions were assessed: (1) what is the maximum peak output of various Bluetooth headsets coupled to a cellular phone; (2) what is the average output of various Bluetooth headsets coupled to a cellular phone; and (3) what is the frequency response of various Bluetooth headsets coupled to a cellular phone? Sixteen Bluetooth headset devices of various manufacturers were used for this study. Bluetooth headsets used for this study were determined by consumer demands and lack of output specifications provided …

Effect Of Parallel Talk On The Language And Interactional Skills Of Preschoolers With Cochlear Implants And Hearing Aids, Sharon A. Raver, Jonna Bobzien, Corrin Richels, Peggy Hester, Anne Michalek, Nicole Anthony

Communication Disorders & Special Education Faculty Publications

Children with profound congenital hearing loss often do not have the same prelinguistic opportunities for social and verbal interaction as their peers with typical hearing [14]. Consequently, language and social skills may be challenging for this group, even after they are provided with amplification or a cochlear implant. This pilot study examined the effectiveness of using a parallel talk intervention to increase the language and interactional skills of three preschoolers with deafnesss. Results revealed that all participants increased verbal turn-taking and that two of the three increased initiated and responded vocal/verbal comments, and initiated and responded nonverbal responses during a …

Effects Of Degree And Configuration Of Hearing Loss On The Contribution Of High- And Low-Frequency Speech Information To Bilateral Speech Understanding, Benjamin W. Y. Hornsby, Earl E. Johnson, Erin Picou

ETSU Faculty Works

Objectives: The purpose of this study was to examine the effects of degree and configuration of hearing loss on the use of, and benefit from, information in amplified high- and low-frequency speech presented in background noise.

Design: Sixty-two adults with a wide range of high- and low-frequency sensorineural hearing loss (5 to 115+ dB HL) participated in the study. To examine the contribution of speech information in different frequency regions, speech understanding in noise was assessed in multiple low- and high-pass filter conditions, as well as a band-pass (713 to 3534 Hz) and wideband (143 to 8976 Hz) condition. To …

Sound Pressure Levels Within The Ear Canal Of Ipod Users, Lawrence E. Bridge

Doctoral Dissertations

Portable listening devices, specifically iPods are becoming more and more popular among teens and young adults. According to Apple's quarterly financial results in March 2008, total iPod sales reached close to 152,000,000 since their release in January 2001 (Apple, 2008). Because nearly 15 million individuals suffer from noise induced hearing loss, listening levels of individuals using iPods are of main concern to audiologists. The purpose of this dissertation is to determine (1) average listening levels of males and females, as well as experienced and inexperienced iPod users and (2) if a certain groups of individuals are at more of a …

Hearing Health In Utah Special Olympics Athletes Compared To Special Olympics Athletes Worldwide: A Prevalence Study In Individuals With Intellectual Disabilities, Lisa Moses Mullins

Theses and Dissertations

The Special Olympics Healthy Athletes initiative promotes wellness of the athletes with intellectual disabilities and education for medical professionals. Healthy Athletes has created a hearing screening program, Healthy Hearing, to help athletes with intellectual disabilities get the otological and audiological care they need. This program promotes a healthy hearing lifestyle and educates medical professionals regarding the need of health care for the intellectually disabled population. The physiologic, otologic, and audiologic abnormalities often occurring in the intellectually disabled population bring special attention for the need to determine the prevalence rate of hearing loss among the athletes participating in Special Olympics events. …

Hearing Loss And Retarded Cochlear Development In Mice Lacking Type 2 Iodothyronine Deiodinase, Lily Ng, Richard J. Goodyear, Chad A. Woods, Mark J. Schneider

Dartmouth Scholarship

The later stages of cochlear differentiation and the developmental onset of hearing require thyroid hormone. Although thyroid hormone receptors (TRs) are a prerequisite for this process, it is likely that other factors modify TR activity during cochlear development. The mouse cochlea expresses type 2 deiodinase (D2), an enzyme that converts thyroxine, the main form of thyroid hormone in the circulation, into 3,5,3'-triiodothyronine (T3) the major ligand for TRs. Here, we show that D2-deficient mice have circulating thyroid hormone levels that would normally be adequate to allow hearing to develop but they exhibit an auditory phenotype similar to that caused by …

Effects Of Occupational Ultrasonic Noise Exposure On Hearing Of Dental Hygienists: A Pilot Study, Jennifer Dunning Wilson, Michele Leonardi Darby, Susan L. Tolle, Joseph C. Sever Jr.

Dental Hygiene Faculty Publications

Purpose. The purpose of this case-control study was to determine whether long-term ultrasonic noise exposure via the dental office environment is related to dental hygienists' hearing status.

Methods. Registered dental hygienists (N - 698) who live in the Hampon Roads areas of Virginia were mailed a Dental Hygiene Word History Questionnaire to determine who would meet the inclusion criteria and would be willing to participate in the study. Consenting subjects were categorized into one of two groups, according to ultrasonic sealer usage rate, and matched on age. Persons with known hearing loss due to infection, disease, or congenital defect were …
