title: Binaural maximum length sequence auditory-evoked brain-stem responses in human adults.
abstract: This study compared monaural and binaural maximum length sequence auditory-evoked brain-stem responses (MLS ABRs) in normal hearing adults. The first experiment demonstrated that reliable binaural MLS ABRs could be recorded which were essentially the same as those recorded monaurally. The second experiment generalized this finding by assessing a range of intensities including threshold stimuli. ABR thresholds, wave V latency x intensity and amplitude x intensity functions, wave V latency and amplitude reproducibility, and waveform reproducibility were comparable for the monaural and binaural MLS ABRs with some minor qualifications. In the third experiment, comparability of monaural and binaural MLS ABRs was generalized to a range of rates from those used conventionally to rates far faster than possible with signal averaging. Again, there was little difference between the binaural and monaural MLS ABRs over the range of rates assessed.
