目的：传统上，听力阈值升高被认为是噪声中难以理解言语的主要原因;然而，尽管听力正常，患者仍经常报告噪声中言语理解困难。本横断面研究的目的是严格评估各种指标的听觉功能（行为阈值和耳声发射）的关系，在噪声中的语音理解在一个大样本的听力正常hearing individual.Design：行为听力阈值，失真产物耳声发射（DPOAE）水平，刺激频率耳声发射水平，和生理噪声（量化使用OAE噪声地板）从921个人之间的10和68岁正常的纯音平均值。快速噪声中语音（QuickSIN）测试结果，量化为信噪比（SNR）损失，被用作噪声中语音理解的度量。采用主成分分析（PCA）和线性回归模型分析噪声环境下听觉功能指标与语音质量指标之间的关系。PCA显示DPOAE水平在12.5至16 kHz与QuickSIN评分的变化显着相关，但相关性较弱（R2 = 0.017）。在所有评估的指标中，较高水平的自生生理噪声占QuickSIN性能的最大方差（R2 = 0.077）。结论：较高水平的生理噪声与听力灵敏度正常的听众的QuickSIN性能较差相关。我们提出，在噪声表演者较差的语音中，生理噪声水平升高可能会降低有效SNR，从而对QuickSIN分数较差的性能产生负面影响。
Objectives:Traditionally, elevated hearing thresholds have been considered to be the main contributors to difficulty understanding speech in noise; yet, patients will often report difficulties with speech understanding in noise despite having audiometrically normal hearing. The purpose of this cross-sectional study was to critically evaluate the relationship of various metrics of auditory function (behavioral thresholds and otoacoustic emissions) on speech understanding in noise in a large sample of audiometrically normal-hearing individuals.Design:Behavioral hearing thresholds, distortion product otoacoustic emission (DPOAE) levels, stimulus-frequency otoacoustic emission levels, and physiological noise (quantified using OAE noise floors) were measured from 921 individuals between 10 and 68 years of age with normal pure-tone averages. The quick speech-in-noise (QuickSIN) test outcome, quantified as the signal-to-noise ratio (SNR) loss, was used as the metric of speech understanding in noise. Principle component analysis (PCA) and linear regression modeling were used to evaluate the relationship between the measures of auditory function and speech in noise performance.Results:Over 25% of participants exhibited mild or worse degree of SNR loss. PCA revealed DPOAE levels at 12.5 to 16 kHz to be significantly correlated with the variation in QuickSIN scores, although correlations were weak (R 2= 0.017). Out of all the metrics evaluated, higher levels of self-generated physiological noise accounted for the most variance in QuickSIN performance (R 2= 0.077).Conclusions:Higher levels of physiological noise were associated with worse QuickSIN performance in listeners with normal hearing sensitivity. We propose that elevated physiological noise levels in poorer speech in noise performers could diminish the effective SNR, thereby negatively impacting performance as seen by poorer QuickSIN scores.
