Speech intelligibility in noise-induced hearing loss: effects of high-frequency compensation

This dissertation examines the frequency response that results in the maximum level of speech intelligibility for persons with noise-induced hearing loss.

Role of alpha synuclein in noise induced hearing loss

The recent discovery of the contribution of alpha synuclein in the auditory system prompted further investigation of its functional role. Auditory brainstem response (ABR) and gap detection testing were completed on wild-type and transgenic M83 mice to assess the role of alpha synuclein in noise-induced hearing loss and central auditory function.

Optimal dose of Kanamycin for protection from noise induced hearing loss

Young CBA/J mice were injected with kanamycin under varying schedules then exposed to noise in order to determine the boundary conditions for cochlear protection against noise.

Efficacy of a combined drug therapy for ameliorating noise-induced hearing loss

Experiments investigated the median effective dose of antiepileptic drugs and synthetic glucocorticoids for the prevention and treatment of noise-induced hearing loss for C57BL/6J mice. We also tested the possible synergistic effects of combining drugs from the two drug families.

Effect of unilateral hearing loss on the speech-evoked auditory brainstem response in the presence of noise

Speech-evoked auditory brainstem responses (ABRs) were acquired in quiet and in the presence of noise at two study sessions to investigate 1) test-retest variability and 2) subcortical representation of speech stimuli. Participants were adults with normal hearing in both ears who listened monaurally and adults with unilateral deafness. Results indicate consistency in responses across sessions and several differences between hearing groups for magnitudes of discrete components.

Temporal processing in listeners with unilateral hearing loss

Temporal processing is examined for sounds delivered to the intact ear of individuals with unilateral hearing, and delivered to one ear of individuals with normal, bilateral hearing. Two temporal processing skills are assessed: 1) the ability to detect sinusoidal amplitude modulation of a wide-band noise, for various modulation frequencies, and 2) the just-noticeable-difference for temporal complexity of random-spectrogram-sounds.

A survey of the distribution of information regarding hearing loss to parents by hospitals and pediatricians in the St. Louis area

This paper discusses a survey undertaken to review information on hearing loss distributed by St. Louis area hospitals and pediatricians.

Effect of amplification bandwidth on intelligibility of several different speech samples for a listener with sensorineural hearing loss

This paper examines the effect of amplification bandwidth on speech intelligibility using multiple speech samples.

Effect of auditory processing on the preference of monaural amplification for adults with symmetrical hearing loss

The purpose of this project was to determine if subjects with symmetrical hearing loss who prefer a monaural hearing aid fit to a binaural hearing aid fit may demonstrate an auditory processing disorder causing them to experience binaural interference when fit binaurally.

An exploration of the role of narrative skills in higher-level reading comprehension of teenagers with hearing loss

This Study examines the relationship between scores on adolescents’ self-generated narratives and standardized reading-comprehension scores. This relationship is also compared with the more simple language metrics: vocabulary and syntax.

Implications of newborn hearing screening: counseling parents of newborns with hearing loss

This paper reviews parental reactions to their newborn newly diagnosed with a hearing loss.

Investigation and literature review of unilateral hearing loss

Literature and research were gathered and analyzed to determine the impact UHL has on a child’s education, speech and language development. The effects of early intervention and amplification were also analyzed.

Newborn hearing screening: examining the presence of risk factors for hearing loss

This paper identifies risk factors associated with hearing loss in newborns, including family history, craniofacial abnormalities, and ototoxic medications.

The role of pediatrician in hearing loss: from detection to connection

This paper presents a study investigating how informed pediatricians are about hearing loss and their ability to assist and refer parents of children with hearing loss.

Development of a high-frequency hearing loss questionnaire for children

The "Pediatric Assessment of Hearing" questionnaire was developed to evaluate how children with high-frequency hearing loss perform in various listening conditions.
