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, interest 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.
对Willeford中央听觉处理测试组的八份录音的电磁特性进行了评估。测量结果表明,当将录音电平参考该测试组给定子测试之前的校准音时,测试项目的录音电平存在显著的磁带间差异、感兴趣差异和声道间差异。快速交替言语感知、低通滤波言语和竞争句子子测试中使用的项目的平均录音电平通常在参考音的10分贝范围内。双耳融合子测试的录音电平产生的磁带间差异高达26.5分贝。鉴于录音电平存在较大的磁带间不一致性,在使用这些录音时应格外谨慎。
