Comments on 'Auditory brainstem responses to middle- and low-frequency tone pips'

This article contains critical comments on data described in a recent paper dealing with differences between click- and tone-pip-evoked auditory brainstem responses (ABR) by Maurizi et al. [Audiology 23: 75-84, 1984]. The primary criticism relates to the lack of validity of comparing ABR obtained with different input filter settings. When utilizing identical input filter settings, click- and tone-pip-evoked brainstem responses exhibit similar morphologies: both consist of a slow vertex-positive wave with faster superimposed vertex-positive components.
