本研究的目的是进一步探讨畸变产物耳声发射（DPOAE）测量和分类响度标度（CLS）测量之间的关系，使用多元线性回归（MLR）分析。最近，Thorson等人[J. Acoust. Soc. Am. 131，1282-1295（2012）]使用MLR分析从DPOAE输入/输出（I/O）函数获得CLS响度等级的预测。本研究通过以下方式扩展了这项工作：（1）考虑两种不同的（可能改进的）MLR模型，一种用于预测指定输入水平下的响度等级，另一种用于预测每个响度类别的输入水平;（2）使用独立的数据集验证新模型的预测。在验证过程中，预测和测量数据之间获得了很强的相关性，总体均方根误差在10.43-16.78 dB范围内预测CLS输入电平，支持DPOAE I/O测量可以预测CLS响度等级和输入电平的观点，因此可能有助于验配助听器。(C)2013年美国声学学会。
The aim of this study is to further explore the relationship between distortion-product otoacoustic emission (DPOAE) measurements and categorical loudness scaling (CLS) measurements using multiple linear regression (MLR) analysis. Recently, Thorson et al. [J. Acoust. Soc. Am. 131, 1282-1295 (2012)] obtained predictions of CLS loudness ratings from DPOAE input/output (I/O) functions using MLR analysis. The present study extends that work by (1) considering two different (and potentially improved) MLR models, one for predicting loudness rating at specified input level and the other for predicting the input level for each loudness category and (2) validating the new models' predictions using an independent set of data. Strong correlations were obtained between predicted and measured data during the validation process with overall root-mean-square errors in the range 10.43-16.78 dB for the prediction of CLS input level, supporting the view that DPOAE I/O measurements can predict CLS loudness ratings and input levels, and thus may be useful for fitting hearing aids.
