[A method for recording auditory evoked brain stem responses for use with objective audiometry and in neurology...

After defining the auditory evoked brain stem responses, the authors discuss the importance of the recording conditions and their influence on the recorded response. The choice of leads, frequency of stimulus repetition and strength of stimulus are all modifying factors. In objective audiometry it seemed preeferable to choose the technical conditions which would highlight wave V, which is identifiable even with stimuli close to threshold. The experimental conditions must be different for neurological investigation because one requires to visualise all the waves constituting the response.
