The Effect Of Grief On Bonding With A Deaf Child, Gabriela Cardona

Senior Honors Projects

Since hearing screenings for children happen after birth, there is no way for

parents to prepare themselves for having a child with hearing loss and any

lifestyle changes that will follow. Many parents have trouble coping with and

accepting the news of having a deaf or hard-of-hearing child. This diagnosis also

often brings along with it the stress of additional necessary appointments and

decisions. The parent’s idea of a “perfect and ideal” child is gone. Parents need

to grieve the loss of this idea while also tending to their child and giving their

child the opportunities and support needed for …

Evaluation Of Hearing Aid Wearers’ Appearance By Individuals Who Do Not Wear Hearing Aid Devices, Lauren M. Lott

Honors Theses

This study focuses on the perception of individuals who do not wear hearing aids and their perception of their hearing aid wearing peers. This thesis considers the opinions of students at The University of Southern Mississippi through the use of a paper survey evaluating the participant’s perception of the following attributes: attractiveness, confidence, motivation, trustworthiness, education, friendliness, intelligence, disability, and body image. Data is collected from 150 students from ages 18-30. This study hopes to determine whether or not there will be a significant change in perception of an individual once they are viewed with a hearing aid.

Effect Of Adaptive Frequency Lowering On Phoneme Identification And Sound Quality Of Music In Hearing-Impaired Listeners, Kaitlyn A. Sabri

Dissertations, 2014-2019

The most common type and configuration of hearing loss seen in clinics is high frequency sensorineural hearing loss. High-frequency hearing losses can lead to difficulties understanding speech in noise. Traditional amplification can aid in audibility of high-frequency information; however, its success is limited due to acoustic feedback, output limitations of the hearing aids, and loudness discomfort (Bohnert, Nyffeler, & Keilmann, 2010, Turner & Cummings, 1999). Cochlear dead regions further hinder the success of traditional hearing aids, as speech recognition may not improve with increased audibility (Turner & Cummings, 1999). Frequency-lowering algorithms, developed by four major hearing aid manufacturers, attempt to …

Modern Prescription Theory And Application: Realistic Expectations For Speech Recognition With Hearing Aids, Earl E. Johnson

ETSU Faculty Works

A major decision at the time of hearing aid fitting and dispensing is the amount of amplification to provide listeners (both adult and pediatric populations) for the appropriate compensation of sensorineural hearing impairment across a range of frequencies (e.g., 160?10000?Hz) and input levels (e.g., 50?75?dB sound pressure level). This article describes modern prescription theory for hearing aids within the context of a risk versus return trade-off and efficient frontier analyses. The expected return of amplification recommendations (i.e., generic prescriptions such as National Acoustic Laboratories?Non-Linear 2, NAL-NL2, and Desired Sensation Level Multiple Input/Output, DSL m[i/o]) for the Speech Intelligibility Index (SII) …

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 …

The Effects Of Hearing Aid Circuitry And Speech Presentation Level On Acceptance Of Background Noise, Ashley Powers Boynton

Doctoral Dissertations

The present study investigated the effects of hearing aid circuitry and speech presentation level on ANL and hearing in noise in 19 adult, bilateral hearing aid users. The acceptable noise level (ANL) procedure was used to assess acceptance of background noise. Conventional ANLs (i.e., measured at the participant's most comfortable listening level (MCL)) and ANLs at eight fixed speech presentation levels were obtained. Then global ANLs (i.e., ANLs averaged over eight fixed speech presentation levels) and ANL growth (i.e., the slope of the ANL function) were calculated Each measure was obtained in three conditions: unaided, aided with wide dynamic range …

The Effects Of Asymmetric Directional Microphone Fittings On Acceptance Of Background Noise, Jong Sik Kim

Doctoral Dissertations

The present study investigated the effects of asymmetric directional microphone fittings (i.e., an omnidirectional microphone on one ear and a directional microphone on the other) on speech understanding in noise and acceptance of background noise in 15 full-time hearing aid users. Subjects were fitted binaurally with four directional microphone conditions (i.e., binaural omnidirectional, asymmetric right directional, asymmetric left directional and binaural directional microphones) using Siemens Intuis directional behind-the-ear hearing aids and comply earmolds. The results revealed that speech understanding in noise improved when using asymmetric directional microphones compared to binaural omnidirectional microphone fittings and were not significantly hindered compared to …

Limiting Noise Exposure Associated With Hearing Aid Use, Alison Mary Gilbert

Dissertations and Theses

Industrial workers who have sustained hearing losses often wear hearing aids on the job in order to hear their co-worker's speech. However they risk damaging their hearing further by amplifying the high levels of background noise typical of such environments. The Occupational Safety and Health Administration (OSHA) has established guidelines to protect workers' hearing. A maximum allowable level of 90 dBA averaged over a period of eight hours is considered safe. Wearing hearing aids on the job may expose an individual to considerably higher levels, however no guidelines as to maximum allowable levels of amplified noise exist at this time. …

Frequency Responses Of Hearing Aids Coupled With Fm Auditory Trainers, Robert Bruce Morrison

Dissertations and Theses

This study examined the frequency response characteristics of three behind-the-ear hearing aids alone and in combination with three FM auditory trainers. The hearing aids and FM auditory trainers were coupled using two different methods: direct audio input and personal mini-loop. Also, two different gain control settings were used. Frequency responses were evaluated using a template method specified in ANSI S3.22 1982 standards. A larger percentage of the personal mini-loop combinations failed to meet this ANSI standard as compared to the direct audio input combinations (72.3% vs. 50%). The frequency response curves for various combinations of hearing aids and FM auditory …

The Output Of Compression Hearing Aids With A Transient Input Signal, Michael Andrew Berg

Dissertations and Theses

The output characteristics of five compression hearing aids in response to a transient signal were examined to determine if, the input-output function (i.e. output levels of the hearing aid as a function of input level) for a transient signal could be made to approximate that of a continuous signal, by activating the compression circuit with a second signal (activator). Input-output functions for three input compression and two output compression hearing aids were obtained in order to determine if: 1. the automatic gain control (AGC) was activated by the second signal and the transient signal output approximates that of a continuous …

A Comparison Of The Expressive Speech Of Profoundly Hearing-Impaired Children : "Hearing Aids On" Versus "Hearing Aids Off", James Allen Henry

Dissertations and Theses

This investigation was conducted to determine whether the removal of hearing aids from these children for eighteen hours (+ 1/2 hour and including sleep time) would result in reduced speech intelligibility as perceived by a panel of listening judges who were unfamiliar with the speech of the deaf.
