Effects Of Dichotic Auditory Training On Children With Central Auditory Processing Disorder, Kiley Edwards Stephenson

Doctoral Dissertations

(Central) auditory processing disorder (CAPD) is a condition in which individuals with normal hearing present with difficulties often associated with hearing loss. While there are currently many tests available for the CAPD assessment, there are very few therapies for the remediation of a CAPD. A new therapy program, called Dichotic Auditory Training (DAT), aimed at improving the performance of those individuals with CAPD, was the focus of this study. Eight children between the ages of seven and twelve went through the four week training. The Staggered Spondaic Word (SSW) test, the SCAN-C/A, and a test designed after the DAT …

Review Of Medical Imaging Devices For The Integration Of Medical Technology And Earmold Production And Grant Proposal Development, Michelle L. Saltarrelli

Doctoral Dissertations

The first purpose of this study was to assess the feasibility of a medical device to replace the current method of earmold production. The medical device would be used to scan the external ear (i.e., external auditory canal and pinna), scan the dimensions to an imaging software system, and finally send the three-dimensional image electronically to a milling machine for the production of earmolds and hearing aid shells. Currently, audiologists use an eight step process described by Dillon (2001) which due to the invasive nature of the procedure presents potential complications to both the clinician and client, The potential complications …

Efficacy Of Central Auditory Processing Case History Form Used At The Louisiana Tech University Speech And Hearing Center, Michelle L. Smith

Doctoral Dissertations

Central auditory processing disorder (CAPD) is a deficiency in processing of auditory information. Due to this deficiency, a variety of behaviors can be seen including listening difficulties in background noise, difficulties following oral instruction, and difficulties discriminating and identifying speech sounds. These behaviors result in inattention and academic difficulties. With these characteristics being present in other disorders such as attention deficit/hyperactivity disorder, language/learning deficits, and high functioning autism (i.e., Asperger's syndrome) diagnosis of CAPD becomes complicated.

The Louisiana Tech University Speech and Hearing Center uses a CAPD case history for a child that was adopted from Robert Keith in 2003. …

A Communication Process Training Model For Use By Audiologists In Counseling, Heather Hendrix

Doctoral Dissertations

Audiologists must assume the role of a counselor when providing interpretation of test results to patients and/or family members. A successful audiologist will rely on the knowledge of auditory disorders and rehabilitation and will be willing to form an effective relationship with the patient through communicative counseling. The purpose of this capstone project is to develop a training protocol for audiologists based on a communication process model. This capstone project discusses the process of designing counseling training sessions.

The basic principles of the Adler and Elmhorst (2002) communication process model were used to develop a dialogue and scenarios (role-playing activity) …

Classroom Acoustics And Intervention Strategies To Enhance The Learning Environment, Christal Savage

Doctoral Dissertations

The classroom environment can be an acoustically difficult atmosphere for students to learn effectively, sometimes due in part to poor acoustical properties. Noise and reverberation have a substantial influence on room acoustics and subsequently intelligibility of speech. The American Speech-Language-Hearing Association (ASHA, 1995) developed minimal standards for noise and reverberation in a classroom for the purpose of providing an adequate listening environment. A lack of adherence to these standards may have undesirable consequences, which may lead to poor academic performance.

The purpose of this capstone project is to develop a protocol to measure the acoustical properties of reverberation time and …

A Protocol For Sound Localization Testing With Young And Aging Normal Hearing Subjects, Alison V. Huff

Doctoral Dissertations

An important aspect of processing auditory stimulus is the ability to localize the source of a sound within the environment. Localization has been defined as the ability to determine the direction of sound (Tonning, 1975; Cranford, Boose, & Moore, 1990; Middlebrooks & Green, 1991; Cranford Andres, Piatz, & Reissig, 1993; Lorenzi Gatehouse, & Lever, 1999; Abel, Giguere, Consoli, & Papsin, 2000). Previous researchers have used a variety of test stimuli, test environments, loudspeaker arrays, and ages and numbers of subjects to measure the ability to localize sounds. Despite the obvious need for individuals to identify the specific location of a …

Sound Localization Accuracy In The Blind Population, Mary Arrington Deloach

Doctoral Dissertations

The ability to accurately locate a sound source is crucial in the blind population to orient and mobilize independently in the environment. Sound localization is accomplished by the detection of binaural differences in intensity and time of incoming sound waves along with phase differences and spectral cues. It is dependent on auditory sensitivity and processing. However, localization ability can not be predicted from the audiogram or an auditory processing evaluation.

Auditory information is not received only from objects making sound, but also from objects reflecting sound. Auditory information used in this manner is called echolocation. Echolocation significantly enhances localization in …

Parental Views Of Otitis Media And Antibiotic Treatment, Courtney Leigh Ross

Doctoral Dissertations

Antibiotic resistance is a rapidly growing problem throughout the world. Antibiotic resistance can be due to a number of factors, including unnecessary antibiotic prescriptions, antibiotic misuse, and transmission of resistant bacteria.

Otitis media is the most often diagnosed childhood illness and accounts for the majority of the United States' annual antibiotic prescriptions. Both parents and physicians can contribute to unnecessary antibiotic treatment for otitis media. Understanding parental views of otitis media and antibiotic treatment may help reduce unnecessary antibiotic prescriptions and lead to the subsequent reduction in antibiotic resistance.

The purpose of this capstone project is to develop a questionnaire …
