[Complementary acoustic EEG control while recording early acoustically evoked potentials].
An easily performed method for the additional acoustical assessment of the EEG quality by the investigator during recording of human brainstem potentials is presented. By means of feedback of the audibly transposed "noiselike" EEG voltage to the opposite ear of the examined subject (instead of the usual masking noise) the subject can perceive self-produced disturbances (muscle activities) and minimize them for the period of examination. An example shows how this additional rejection of artifacts via "biofeedback" can effectively support methods that are already in use.
