Electromagnetic characteristics of eight tape recordings of the Willeford Central Auditory Processing Test Battery were assessed. Measurements indicate that when recording levels are referenced to the calibration tone preceding a given subtest of that battery, significant intertape differences, intertest differences, and interchannel differences in the recording levels of test items exist. Mean recording levels of items used in the Rapidly Alternating Speech Perception, Low-Pass Filtered Speech, and Competing Sentences subtests typically were within 10 dB of the reference tone. Recording levels for the Binaural Fusion subtest yielded intertape differences of as much as 26.5 dB. Given the large intertape inconsistencies in recording levels, extreme caution should be exercised in the use of these recordings.
