Brain-Stem Auditory-Evoked Responses in High-Risk Infants

Brain-Stem Auditory-Evoked Responses in High-Risk Infants This article is only available in the PDF format. Download the PDF to view the article, as well as its associated figures and tables. Abstract The effect of high levels of ambient acoustic noise on the results of auditory brain-stem (evoked) response (ABR) screening programs for high-risk infants has never been well documented. Consequently, Kenneth Richmond, MD, Dan Konkle, PhD, and William Potsic, MD, Department of Otolaryngology and Communication Disorders, Children's Hospital, Philadelphia, examined the ABR waveforms obtained at various levels of stimulus intensity and background noise. The subjects were ten adults and ten high-risk infants whose ABRs were judged normal when measured at a 20-dB nHL stimulus in a quiet condition. Ambient noise was measured in the infant care nursery and then accurately reproduced in the sound field of an audiometric booth. Auditory brain-stem (evoked) responses were obtained from each subject for stimulus intensities ranging from 20 to 80 dB nHL in a quiet condition and were repeated at background noise levels of 40, 50, and 60 dBA. These background noise levels corresponded roughly http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Otolaryngology - Head & Neck Surgery American Medical Association
