Estimating residual noise in the auditory brain-stem response.
Estimation of the residual noise in the auditory brain-stem response waveform is considered. The residual noise measures one aspect of waveform quality. Moreover, it is an important component of signal detection algorithms used for automatic termination of the test. It is shown that the most commonly used method for estimating residual noise can be severely biased. Reasons for this bias are explored and two alternative estimators are presented.
