An Impedance Tube Technique For Estimating The Insertion Loss Of Earplugs, K. Carillo, O. Doutres, F. Sgard

Études primaires

This paper proposes a quick and straightforward technique for estimating the insertion loss (IL) of earplugs measured on an acoustical test fixture (ATF) using a commercial impedance tube. In this method, the earplug's acoustic properties (i.e., its transmission loss and the reflection coefficient of its medial surface) are determined from its transfer matrix measured using the three-microphones impedance tube method modified here for the current application. The IL is then estimated using a one-dimensional analytical model of open and occluded earcanals based on the wavefield decomposition theory. The method is evaluated numerically and experimentally from 50 Hz to 6.5 kHz. …

METHOD: Participants included 26 full-time, female school teachers between 23 and 55 years of age across multiple grades and subjects, including individuals with and without a voice disorder. Ambulatory voice data were collected …

Feasibility Of An Abstract Verb Naming Treatment For Aphasia, Dallin J. Bailey, Lisa Bunker, Julie L. Wambaugh

Faculty Publications

Purpose

Verb production impairments in aphasia have important implications for sentence production and communication in general. Verbs with low concreteness may be especially important for certain functional uses, and yet limited data regarding their response to treatment are available. This study was designed to examine a novel behavioral treatment approach to improve low concreteness verb naming in persons with aphasia.

Method

Three persons with nonfluent aphasia participated in a single-subject experimental design research study examining the feasibility of the novel treatment. The treatment was based on approaches that target the verb as the central node of meaning during sentence construction. …

Collaborative Practices Between General Education Teachers And Teachers Of The Deaf/Hard Of Hearing: A Narrative Inquiry, Kayla Power

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

The US Individuals with Disabilities Education Act (2004) states that students with disabilities should receive instruction in the general education classroom as much as possible. This move has resulted in Deaf/Hard of Hearing (DHH) students spending more of their time in the general education classroom which has increased the need for collaboration between Teachers of the Deaf (TODs) and general education teachers. The purpose of this qualitative study is to examine what collaboration between TODs and general education teachers looks like in an elementary school setting. Data consisted of individual interviews and observations. Using a narrative inquiry approach, I restory …

Trumpet Directivity From A Rotating Semicircular Array, Samuel D. Bellows, Joseph E. Avila, Timothy W. Leishman

Directivity

The directivity function of a played musical instrument describes the angular dependence of its acoustic radiation and diffraction about the instrument, musician, and musician’s chair. Directivity influences sound in rehearsal, performance, and recording environments and signals in audio systems. Because high-resolution, spherically comprehensive measurements of played musical instruments have been unavailable in the past, the authors have undertaken research to produce and share such data for studies of musical instruments, simulations of acoustical environments, optimizations of microphone placements, and other applications. The authors acquired the data from repeated chromatic scales produced by a trumpet played at mezzo-forte in an anechoic …

Recursive Functional Learning In Nonfluent Aphasia, Gerald C. Imaezue

Dissertations, Theses, and Capstone Projects

People with nonfluent aphasia (PWNA) require feedback from an external agent as well self-feedback to facilitate performance of language production tasks. The extent to which PWNA can use self-feedback alone to improve their task performance is unknown. In addition, it is argued that self-feedback may reinforce or minimize performance errors over time. To test whether either is the case, we introduce an original learning mechanism, recursive functional learning, which uses self-feedback loops to optimize recursively multiple subsystems (cognitive and linguistic subsystems) that PWNA engage during task performance. We used this mechanism to underpin a novel automated procedure we developed, recursive …

The Directional Effect Of Target Position On Spatial Selective Auditory Attention, Heesung Park

Dissertations, 2020-current

Spatial selective auditory attention plays a crucial role in listening in a mixture of competing speech sounds. Previous neuroimaging studies have reported alpha band neural activity modulated by auditory attention, along with the alpha lateralization corresponding to attentional focus. A greater cortical representation of the attended speech envelope compared to the ignored speech envelope was also found, a phenomenon known as 'neural speech tracking’. However, little is known about the neural activities when attentional focus is directed on speech sounds from behind the listener, even though understanding speech from behind is a common and essential aspect of daily life. The …

New Mexico Teachers’ Perceptions Of Students Who Stutter, Kyla Evelyn Cook

Speech and Hearing Sciences ETDs

Although stuttering may have a negative impact on quality of life, social support can mediate this impact and result in better outcomes. Teachers can be an important support for children. However, studies have shown that teachers have similar biases and knowledge compared to the public, and therefore may hold harmful beliefs about their students who stutter. This online survey is part of the assessment phase that aims to investigate the local attitudes and beliefs of K-12 school teachers in New Mexico. The data showed that New Mexico teachers have similar knowledge and biases as teachers globally. Results indicate New Mexico …

Non-Negative Matrix Factorization Improves The Efficiency Of Recording Frequency-Following Responses In Normal-Hearing Adults And Neonates., Fuh-Cherng Jeng, Tzu-Hao Lin, Breanna N Hart, Karen Montgomery-Reagan, Kalyn Mcdonald

Ambulatory and Primary Care Articles

OBJECTIVE: One challenge in extracting the scalp-recorded frequency-following response (FFR) is related to its inherently small amplitude, which means that the response cannot be identified with confidence when only a relatively small number of recording sweeps are included in the averaging procedure.

DESIGN: This study examined how the non-negative matrix factorisation (NMF) algorithm with a source separation constraint could be applied to improve the efficiency of FFR recordings. Conventional FFRs elicited by an English vowel/i/with a rising frequency contour were collected.

RESULTS: The improvements of FFR recordings, defined as the correlation coefficient and root-mean-square differences across a sweep series of …

Sound-Category Learning And Memory Skills In Neurotypical Adults And Adults With Language-Learning Disabilities, Allison Fulcher

University Honors Theses

This study evaluates the impact of memory skills (procedural, declarative, and working) and sound discrimination abilities, on the ability of adults with and without Language Learning Disability (LLD) to learn two sound-category structures, one designed to be learned implicitly and the other designed to be learned explicitly. This design tests a theorized etiology for LLD, the Procedural Deficit Hypothesis (PDH), which posits that LLD is caused by selective impairments to procedural memory and implicit learning. It also serves to evaluate factors and conditions that contribute to success in second-language learning for adults, who are less neurologically suited to the task …

Gender Diversity Cultural Responsiveness Education In Speech-Language Pathology Graduate Programs: A Pilot Survey, Tara E. Dickinson, Molly A. Normandin, Rachel W. Mulheren

Teaching and Learning in Communication Sciences & Disorders

Purpose: Gender-affirming voice therapy aims to align a person’s voice and communication with their gender identity. Historically, transgender and gender-nonconforming (TGNC) individuals have been marginalized and continue to face significant healthcare disparities. The goal of this research was to examine the self-perceived preparedness of recent speech-language pathology (SLP) graduates for working with TGNC clients. A survey was developed to include both multiple choice and open-ended questions. Topics included graduate-level training on working with TGNC individuals, perceived preparedness to work with this client population, educational resources sought by respondents, and suggested improvements for SLP graduate programs. Thirty recent (since 2016) …
