In a sample of 425 subjects, pure-tone hearing thresholds between the right and left ears were shown to have an average correlation of .885 (or .783 with age partialed out). This high interaural correlation is shown to invalidate the experimental procedure of entering data on the basis of "ears," where each subject can contribute one or two audiograms to the data pool, since such aggregation is demonstrated to produce spuriously high levels of apparent statistical significance in inferential statistical tests.
在425名受试者的样本中，右耳和左耳之间的纯音听力阈值平均相关性为0.885（去除年龄因素后为0.783）。这种较高的双耳相关性表明，基于“耳朵”输入数据的实验程序是无效的，因为每个受试者可以为数据池贡献一到两份听力图，而这种汇总在推断性统计测试中会产生虚假的高显著水平。
