Summary, etc | Objective: To use cortical auditory evoked potentials (CAEPs) to understand neural encoding in background<br/>noise and the conditions under which noise enhances CAEP responses.<br/>Methods: CAEPs from 16 normal-hearing listeners were recorded using the speech syllable/ba/presented<br/>in quiet and speech-shaped noise at signal-to-noise ratios of 10 and 30 dB. The syllable was presented<br/>binaurally and monaurally at two presentation rates.<br/>Results: The amplitudes of N1 and N2 peaks were often significantly enhanced in the presence of lowlevel<br/>background noise relative to quiet conditions, while P1 and P2 amplitudes were consistently<br/>reduced in noise. P1 and P2 amplitudes were significantly larger during binaural compared to monaural<br/>presentations, while N1 and N2 peaks were similar between binaural and monaural conditions.<br/>Conclusions: Methodological choices impact CAEP peaks in very different ways. Negative peaks can be<br/>enhanced by background noise in certain conditions, while positive peaks are generally enhanced by binaural<br/>presentations.<br/>Significance: Methodological choices significantly impact CAEPs acquired in quiet and in noise. If CAEPs<br/>are to be used as a tool to explore signal encoding in noise, scientists must be cognizant of how<br/>differences in acquisition and processing protocols selectively shape CAEP responses.<br/>Published by Elsevier Ltd. on behalf of International Federation of Clinical Neurophysiology. |
