Objective Vs. Subjective Hearing Screening Measures In Schools, Brittany S. Brown
Objective Vs. Subjective Hearing Screening Measures In Schools, Brittany S. Brown
Doctoral Dissertations
The primary aim of this study was to demonstrate the need for objective hearing screening procedures within traditional school based hearing screenings through literature review. It is believed that objective hearing screenings would provide a better, less-invasive way to screen hearing with minimal participation required from the children, and less interpretation needed from the examiner. A review of the literature suggested that ideal screening measures would include otoacoustic emissions (OAEs) and tympanometry. Currently, the gold standard for school hearing screenings, as described by the American Speech Language Hearing Association (ASHA) (1997), centers on behavioral responses observed by the examiner during …
The Effects Of Hearing Aid Circuitry And Speech Presentation Level On Acceptance Of Background Noise, Ashley Powers Boynton
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 Clinical Application Of Progressive Filtering In Normal And Disordered Populations, Sarah M. Johnson
The Clinical Application Of Progressive Filtering In Normal And Disordered Populations, Sarah M. Johnson
Doctoral Dissertations
The present study examined the effect of progressive filter testing in children with normal auditory processing skills and children with (central) auditory processing disorders [(C)APD]. The primary purpose of this study was to determine if a new screening procedure designed by the investigator called Progressive Filtering would differentiate between a control group (i.e. children with normal auditory processing skills) and an experimental group [children with (C)APD]. Twenty subjects (age 6 to 14 years) participated in the study. All subjects received an audiological examination, an auditory processing test battery, and the Progressive Filtering screening tool. Results indicated that the investigator-designed Progressive …
