Comparison Of The Modal Frequency Levels Of Nonsmoking And Cigarette Smoking White Females Between The Ages Of Forty And Fifty Years, Janis Mae Kaufman

Dissertations and Theses

Acoustical analyses have been utilized to ascertain the functional status of the laryngeal mechanism for clinical management of communication disorders. In particular, the modal frequency level (MFL), defined as the fundamental frequency most often used by an individual in the act of spontaneous speech, is one measurement used to determine if a person's pitch level is adequate. Two other pitch measurements used in the voice assessment are the maximum frequency range (MFR) and the optimum pitch level (OPL). Information is needed to provide guidelines for pitch levels as part of the voice evaluation for adult females of different ages. It …

High Frequency Acoustic Reflexes In Cochlea-Impaired And Normal Ears, Karen Elizabeth Jones

Dissertations and Theses

The acoustic reflex refers to the contraction of a middle ear muscle in response to sound. The contraction causes a stiffening of the middle ear system and, consequently, the flow of acoustic energy to the cochlea is impeded. By measuring the change in admittance in the auditory system during sound stimulation it is possible to indirectly monitor the middle ear muscle contractions. Such measurements provide useful information regarding the integrity of the auditory system and the location of the auditory pathology.

In subjects with normal hearing sensitivity, the acoustic reflex is typically elicited at a sensation level of between 85 …

A Comparison Of Two Vocabulary Tests Used With Normal And Delayed Preschool Children, Lynn Safadi

Dissertations and Theses

The purpose of this study was to determine if a difference exists between mean standard scores of the Peabody Picture Vocabulary Test - Revised (PPVT-R) (Dunn and Dunn, 1981) and the Expressive One-Word Picture Vocabulary Test (EOWPVT) (Gardner, 1979) for children in several diagnostic categories. The subjects used in this study were 45 preschool children ranging in age from 36 to 47 months. These subjects were divided into groups of normal, expressively language-delayed (ELD) and normal children with a history of expressive language delay (HELD).

Intelligibility Of Spondees Via Bone Conduction At Elevated Presentation Levels, Pamela S. Ritchie

Dissertations and Theses

Speech reception threshold testing by bone conduction is very useful in diagnostic audiometry. However, there are little data regarding the CID W-1 spondee word lists used with the Radioear B-71 and B-72 and Pracitronic KH 70 bone conduction vibrators at higher presentation levels for testing hearing impaired clients. Data are needed in order that results of speech reception thresholds using the CID W-1 word lists via these three bone conduction vibrators at higher intensity levels can be used confidently in the clinic. More data are available for speech reception thresholds using the CID W-1 word lists via earphones.

This study …

Developmental Sentence Scoring Sample Size Comparison, Peggy Ann Callan

Dissertations and Theses

In 1971, Lee and Canter developed a systematic tool for assessing children's expressive language: Developmental Sentence Scoring (DSS). It provides normative data against which a child's delayed or disordered language development can be compared with the normal language of children the same age. A specific scoring system is used to analyze children's use of standard English grammatical rules from a tape-recorded sample of their spontaneous speech during conversation with a clinician.

The corpus of sentences for the DSS is obtained from a sample of 50 complete, different, consecutive, intelligible, non-echolalic sentences elicited from a child in conversation with an …

Otitis Media And Language Development In Late Talkers, Timothy Forest Lynn

Dissertations and Theses

While there is agreement in the literature that otitis media is an extremely prevalent disorder among young children, there is disagreement as to the effect that otitis media has on language development. The lack of definitive research attests to the complexity of the issue and to the need for continued research.

This study examined the relationship between an early history of otitis media and the language development of a group of "late talkers". The 28 toddlers in this group, while otherwise normal, were late to begin to speak. Each of the subjects was placed into one of two subgroups, depending …

Hearing Aid Satisfaction And Rate Of Return For Repairs: A Comparison Of Two Kaiser Dispensing Programs, Lynn L. Behrendsen

Dissertations and Theses

The purpose of this study was to investigate the hypothesis that a dispensing program utilizing rehabilitative follow-up in the form of a post-fitting check appointment would show: (1) less return for repairs for hearing aids; (2) higher patient satisfaction with the aid; and (3) higher patient satisfaction with the service received during the hearing aid dispense than would a clinic with no follow-up. Data for comparison between the two clinics were drawn from medical chart review, frequency of hearing aid repairs, and from a questionnaire which assessed satisfaction levels. Patients were also asked to estimate the amount of use with …

The Assessment Of Phonological Processes : A Comparison Of Connected-Speech Samples And Single-Word Production Tests, Susan A. Pinkerton

Dissertations and Theses

The purpose of this study was to determine if single-word elicitation procedures used in the assessment of phonological processes would have highly similar results to those obtained through connected speech. Connected speech sampling provides a medium for natural production with coarticulatory influence, but can be time-consuming and impractical for clinicians maintaining heavy caseloads or working with highly unintelligible children. Elicitation through single words requires less time than a connected-speech sample and may be more effective with highly unintelligible children because the context is known, but it lacks the influence of surrounding words. Given the inherent differences between these two methods …

An Investigation Of Three Strategies To Enhance Generalization Of Conversational Skills, Janice Ann Cain

Masters Theses

The purpose of the present study was to investigate the effects of three strategies to enhance generalization of taught conversational skills: (1) multiple and varied scenarios, (2) multiple conversational partners, and (3) homework assignments. A multiple baseline across behaviors design tested whether the initial training package produced generalization to the probe sessions and whether the addition of homework would produce greater generalization to the probe sessions compared to that observed during the initial training. Four adults, one male and three female, ranging in age from 20-64 years served as subjects. Skills were taught using a combination of coaching, modeling, behavioral …

Standardization Of Oral Cloze As A Language Assessment Device For Bilingual Hispanic Children, Shannon Ventuleth

Loma Linda University Electronic Theses, Dissertations & Projects

This present study was initiated to determine the feasibility of oral cloze procedures as a language screening for bilingual Hispanic students. If such a procedure were normed, and proven to be both reliable and valid, the resultant assessment device would have potential screening tool as a for determining the presence of a language disorder in the bilingual Hispanic child aged 8 through 10 years.

A review of current tests available, and a review of the literature, revealed few language tests designed specifically for and normed on bilingual Hispanic children. Tests available for bilingual Hispanic children over 7 years of age …

Acoustic Characteristics Of Vowels Produced By Men, Women And Children, Laura Arlene Getty

Masters Theses

This investigation was a replication and extension of Peterson and Barney’s (1952) research on the acoustics and perception of vowels. This study explored the acoustic characteristics of 12 vowels produced by 50 men, 50 women and 41 children. Speech samples were tape recorded as subjects read lists of words and isolated vowels. Speech samples were digitized. Speech waveforms, spectrograms and formant frequencies were examined and measured.

The average formant frequency values were similar but not identical to the values reported by Peterson and Barney (1952). The largest discrepancy between the two studies was the degree of overlap among vowel categories, …

Identification Of Dyspraxic Characteristics In Children With Moderate And Severe Articulation Disorders, Gail Woodward

Dissertations and Theses

The purpose of this investigation was to determine if public school children with moderate and severe articulation disorders exhibit dyspraxic characteristics on a standardized developmental dyspraxia screening test.

Visual Speech Training Aid For The Deaf, Subhashri Venkat

Electrical & Computer Engineering Theses & Dissertations

A computer-based vowel articulation training aid has been developed. A "continuous" acoustic-phonetic transformation is performed to map speech parameters to a lower dimensionality display space. There are two possible approaches to this transformation problem. The transformation could be either linear or a combination nonlinear/linear. The nonlinear transformation is performed using a multi-layered feedforward neural network with linear output layers. Speech parameters are extracted either from an analog filter bank arrangement (band energies) or by a digital signal processing procedure (Discrete Cosine Transform Coefficients). The speech parameters obtained from both methods correspond to the spectral envelope of the speech signals. The …

Analogical Reasoning Of Elderly Adults Using Three Modalities: Words, Pictures, And Figures, Judy L. Rau

Masters Theses

This study examined the analogical processing skills of elderly adults. Forty-seven subjects (ages 65-90) completed analogy tasks presented in three modalities: words, pictures, and geometric figures (90 total). The subjects for this study were elderly adults living independently in a federally subsidized apartment building. The subjects used in this study possessed characteristics similar to the "typical" American adult. Results indicated that performance does not vary significantly with age in the word and picture modalities. Significant (p < .05) negative relationships were found between performance on the geometric figure analogies and increased age and between overall performance and increased age. Significant (p < .05) positive relationships were found between education and performance on each of the three modalities as well as between education and overall performance.

Perceptual Effects Of Perturbation And Additive Noise, Richard E. Nero

Masters Theses

This study investigated the perceptual effects of varying glottal waveshape perturbation, duty cycle perturbation, jitter, signal-to-noise ratio perturbation, and shimmer at three levels of perceived magnitude (high, medium, and low). Voice signals were synthesized using a modified version of Klatt's (1980) formant synthesizer. Listeners rated signal dysphonia using an A-B dissimilarity procedure. Multidimensional scaling analysis suggested that signals judged low in magnitude of dysphonia were perceived to be most similar. Medium-level and high-level magnitude signals were judged to be respectively less similar. Signals varying in duty cycle and fundamental frequency perturbation were perceived to be very similar while those signals …

The Application Of Automated Programmed Instruction To The Modification Of Auditory Processing In The Aphasic Patient, Cara Anderson

Speech and Hearing Sciences ETDs

A review of the literature suggests that treatment of the aphasic patient, particularly in the area of auditory input has been and is inadequate at this time. Improved methods of diagnosing and evaluating the levels of communicative ability of aphasic patients, indicate that newly developed techniques would seem to be appropriate for the treatment of auditory input deficits.

The present study, therefore, was designed to investigate two questions: (1) is operant conditioned, programmed instruction as designed and instrumented in this study, a useful and mechanically feasible approach to the treatment of aphasia and (2) are operant conditioned programmed instruction methods …

The Duration Of Tinnitus In An Aging Population, Mary Engel

Dissertations and Theses

The purpose of the present study was to determine whether the perceived severity of chronic tinnitus in a geriatric population increased, decreased, or remained constant with the passage of time. A questionnaire was designed to ascertain the subjects' perceived severity at time of onset and the perceived severity of their current tinnitus. The subjects were asked to rate their past and present tinnitus severity according to how much it bothered them. They were also asked questions pertaining to noise exposure history, hearing aid use, and tinnitus sound parameters for purposes of comparison with other groups previously studied.

Differentially Diagnosing Stuttering In Young Children Using The Stuttering Severity Instrument, Brenda Pekkola Teich

Dissertations and Theses

Young children between the ages of two and six years often exhibit partword, whole word. and phrases repetitions as their language develops. This is also the age range when stuttering most frequently appears. Consequently. speech-language pathologists need diagnostic criteria and evaluation tools to distinguish between the incipient stutterer and the normally disfluent child.

Today a widely used evaluation tool is the Stuttering Severity Instrument (SSI) (Riley, 1972, 1980). The SSI is designed to provide a severity level based upon the parameters of frequency. duration. and physical concomitants. Riley (1972) first designed the SSI to not include monosyllabic word repetitions in …

Teacher And Student Discourse Variables In Academic Communication, Janet M. Sturm

Masters Theses

This study was designed to analyze the oral communication exchanges between first, third, and fifth grade teachers and their students. It was based on the hypothesis that discourse parameters of linguistic quantity and complexity and communication acts change over grade level, much as the discourse parameters of caregivers with young children have been found to do. The language of teachers and students in 15 classrooms was examined by measuring 6 form and quantity variables and 11 communication act variables. Results showed significant differences for some form variables (MLU, mazes, and Type-token ratio) and some communication acts (convey content, mark content, …

A Comparison Of Two Methods For Measuring The Attenuation Provided By Insert-Type Hearing Protection Devices, Brenda Barrett Kabat

Dissertations and Theses

The need for hearing protection in industry has evolved from the growing awareness of the detrimental effects of noise on hearing and recent legislation enacted to protect the hearing of noise-exposed employees through the use of hearing conservation programs. In lieu of expensive or impractical engineering and administrative controls, personal hearing protection devices (HPDs) are considered to be the most practical and effective means of protecting employees from the damaging effects of noise in industry today.

Speech Pathology And Audiology At Western: A Brief History, Charles Van Riper, Frank B. Robinson

Histories of Western Michigan University

This historical telling of Western Michigan University's Department of Speech, Language and Hearing Sciences was written by Dr. Charles Van Riper and Dr. Frank B. Robinson. The brief history describes how Dr. Van Riper built a clinic and developed fledgling profession of speech pathology. Hired in 1936 by Dr. Sangren, Van Riper used his skills as a clinician and as a gifted teacher to recruit students, design courses and acquaint the public with the services offered at a mobile speech clinic. By 1938, the first students majoring in “speech correction” were graduated and employed in public schools. By 1939, the …

A Comparison Of An Acoustic Stethoscope And An Amplified Stethoscope In White Noise And Cafeteria Noise During Cardiac Auscultation, Lynda Lynell Gigstad

Dissertations and Theses

A basic relationship between stethoscopic auscultation and background noise interference was reviewed and examined in this study. The principle experimental design of the study questioned whether hospital background noise levels are capable of masking the threshold of detection for auscultated heart sounds. Several cited studies monitoring background noise levels in various hospital locations have reported averages exceeding the U.S. Environmental Protection Agency (EPA) (1974) and World Health Organization (WHO) (1980) recommendations of "quiet", namely 35 to 40 dBA (Falk & Woods, 1973; Hilton, 1985, 1987; Shapiro & Berland, 1972; Turner, et al., 1975; Woods & Falk, 1974) by as much …

Pragmatic Conversational Skills Of Children Identified As Emotionally Disturbed, Deidre Winder

Dissertations and Theses

Communication refers to the conveyance of intended messages so that the listeners' attitudes, beliefs, or behaviors are changed. Communication through a language system may be thought of as the integration of the three components of content (semantics), form (syntax), and use (language in context or pragmatics). The corning together of content, form, and use in signs, words, phrases, and discourse is the essence of language development. The synergism of content/form/use makes up language competence, or knowledge. When children speak and understand a message, they have a plan that is knowledge of language and they use that plan for the behavior …

Audiological In-Service Regarding Hearing Impairment And Its Impact On Communication In The Geriatric Population, Marie Barlow Lassell

Dissertations and Theses

At least two studies have been found conducted in the area of audiological in-services and their impact on the people to whom they were presented. In 1981, Dancer and Keiser studied the effects of empathy training on geriatric-care nurses and in 1985, Dampier, Dancer, and Keiser studied changing attitudes of college students toward older persons with hearing loss. Both of the studies investigated the effect of in-service training on empathy, rather than using the traditional academicallyoriented in-service program approach. Both studies found statistical results indicating a significant positive change in the subjects' feelings toward hearing impaired geriatrics. Additionally, Dancer et …

Communication Repair Strategies Utilized By Hearing-Impaired And Normal-Hearing Children, Mary Kay Herder

Dissertations and Theses @ UNI

The present study was designed to examine the abilities of normal-hearing (NH) and hearing-impaired (HI) children to repair communication breakdowns utilizing non-primary modalities (writing, drawing , showing, etc.) when listeners did not comprehend their primary mode of communication . The subjects for this study were 8 children with moderate to profound hearing losses. Hearing status for the HI subjects was no better than PTA of 39 dB HL (ANSI, 1969). The HI subjects ranged in age from 5 years, 2 months to 13 years, 1 month with a mean age of 8 years, 4 months . Each HI subject was …

The Use Of Phonological Process Assessment For Differentiating Developmental Apraxia Of Speech From Functional Articulation Disorders, Kathryn Dearmond

Dissertations and Theses

Focus has turned from emphasis on phonetic sound errors to phonologic rule systems in the study of articulation disorders. The current theory proposes that the phonological disorders which children experience are controlled by higher levels in the brain than those that control the motor functioning of the brain. The purpose of the present study was to compare the use of phonological processes by a group of school-age children with moderate to severe multiple articulation disorders (MAD) with developmental apraxia of speech (DAS) to the phonological processes used by those without developmental apraxia of speech. For the purposes of this study, …

The Relationship Between Untrained Listener Perceptions And Disordered Voices, Donald S. Finan

Masters Theses

The ability of trained listeners to make judgments of voice quality has been well documented. This study is designed to investigate untrained listeners' ability to make quality judgments of male and female produced normal, breathy, harsh, and hypernasal voice qualities. Research purposes are as follows:

1. To test if untrained listeners tend to reliably assign specific positive or negative descriptive adjectives according to vocal quality.

2. To determine if specific disordered vocal qualities carry more negative rating than others.

A series of actors and actresses were trained to produce the disordered voice qualities of breathy, harsh, and hypernasal according to …

The Use Of The California Consonant Test And The Northwestern University Auditory Test No. 6 In Hearing Aid Evaluations For Individuals With Precipitous Losses Above 1 Khz, Bradley James Allard

Dissertations and Theses

These two joint-studies used recorded versions of the Northwestern University Auditory Test Number 6 (NU-6) and the California Consonant Test (CCT) in the hearing aid evaluations (HAEs) of 12 male and one female subjects, aged 41 to 87 years. They exhibited precipitous high frequency losses beyond 1 kHz in at least one ear. All subjects were evaluated without amplification and while monaurally aided with two conventional high pass hearing aids. Ten of the subjects were evaluated in multi-talker noise and 11 were tested in quiet. Since the CCT was more heavily weighted than the NU-6 with target phonemes sensitive to …

Written Narratives Of Language Disordered And Normal Adolescents On Two Tasks, Antigone Howick Brown

Dissertations and Theses

The purpose of this study was to describe written narratives of language disordered adolescents by comparing their written narratives via story grammar analysis with those of normal adolescents. The written narratives were obtained by administering two tasks as required assignments within the English or communications classes of the two groups. Task A was to write about a personal experience and Task B was about an imaginary experience. This study used Merritt and Liles' adaptations (1987) of Stein and Glenn's procedures (1979) for story grammar analysis to describe the content of the narratives.
