Samuel B. Burchfield, Ph.D.
Pediatric audiology, aural rehabilitation, and pre-linguistic development. Current research projects are examining the relationship between syllable perception and production in infants with hearing loss as well as assessment methods used in pediatric populations.
Dr. Burchfield, after a thirty year career in didactic and clinical teaching, is working on the Acceptable Noise Level (ANL) program with Dr. Anna Nabelek. The aim of this endeavor is to determine if people reject hearing aids because of their inability to accept background noise. Acceptance of background noise has been found to be a stable but highly individualistic response. Three independent preliminary investigations, using small subject cohorts, have shown that successful hearing aid users accept more background noise than unsuccessful users. The relationship between background noise acceptance and hearing aid use is currently being examined in a cohort of over 200 subjects (National Institute On Deafness and other Communication Disorders, NIH, R01 DC05018).
The relationship between acceptance of background noise and hearing aid directivity is also currently being examined in a companion project (National Institute On Deafness and Other Communication Disorders, NIH, R01 DC05018S).
