许多耳鸣患者报告说，尽管在听力阈值方面听力“正常”，但在嘈杂声或与之竞争的说话者中，他们理解言语有困难。耳鸣引起的干扰更可能是中央起源。竞争性言语产生的信息掩蔽（来源更集中）的释放可能进一步阐明耳鸣引起的中枢干扰。在本研究中，我们测量了有或没有耳鸣的正常听力听者的隐蔽性言语理解。在存在多说话人的胡言乱语或竞争语音的情况下，测量目标语音的语音识别阈值。对于竞争语音，在不同的线索条件下测量语音识别阈值（即，有无目标掩蔽者性别差异和/或有无空间线索）。目前的数据表明，即使在没有可测量的听力损失的个体中，耳鸣也会对隐藏语音识别产生负面影响。耳鸣的严重程度似乎特别限制了听者利用说话者的性别差异来区分竞争语音的能力。这些数据表明，通过词汇干扰增加的信息掩蔽可能会消耗耳鸣患者的中枢听觉加工资源。
Many tinnitus patients report difficulties understanding speech in noise or competing talkers, despite having “normal” hearing in terms of audiometric thresholds. The interference caused by tinnitus is more likely central in origin. Release from informational masking (more central in origin) produced by competing speech may further illuminate central interference due to tinnitus. In the present study, masked speech understanding was measured in normal hearing listeners with or without tinnitus. Speech recognition thresholds were measured for target speech in the presence of multi-talker babble or competing speech. For competing speech, speech recognition thresholds were measured for different cue conditions (i.e., with and without target-masker sex differences and/or with and without spatial cues). The present data suggest that tinnitus negatively affected masked speech recognition even in individuals with no measurable hearing loss. Tinnitus severity appeared to especially limit listeners’ ability to segregate competing speech using talker sex differences. The data suggest that increased informational masking via lexical interference may tax tinnitus patients’ central auditory processing resources.
