Questions are raised about the technical and psychological interpretation of loudness match measures in the assessment of tinnitus "intensity". The effect of hearing threshold on loudness matches expressed in sensation level (SL) was investigated by selecting subjects with different degrees of hearing loss. The loudness match expressed in SL was found to be a function of threshold. Correlations were then determined between psychological scales of tinnitus complaint (reported loudness, distress, intrusiveness, and others) and loudness match expressed in HL, SL, sones, or personal loudness units (PLUs). Only matches expressed in PLUs were significantly correlated with reported loudness or other psychological scales. The PLU transformation, derived from an individually determined loudness function, produces values that are generally independent of other audiometric measures. It is therefore recommended for assessing tinnitus "intensity".
关于耳鸣“强度”评估中响度匹配测量的技术和心理学解释存在一些问题。通过选择不同程度听力损失的受试者，研究了听力阈值对以感觉级（SL）表示的响度匹配的影响。发现以SL表示的响度匹配是阈值的函数。然后确定耳鸣主诉的心理量表（报告的响度、痛苦程度、侵扰性等）与以听力级（HL）、SL、宋或个人响度单位（PLU）表示的响度匹配之间的相关性。只有以PLU表示的匹配与报告的响度或其他心理量表显著相关。从个体确定的响度函数导出的PLU转换产生的值通常独立于其他听力测量值。因此，推荐使用它来评估耳鸣“强度”。
