This study tested the hypothesis that word recognition in a complex, two-talker masker is more closely related to real-world speech perception for children with hearing loss than testing performed in quiet or steady-state noise.
Sixteen school-age hearing aid users were tested on aided word recognition in noise or two-talker speech. Unaided estimates of speech perception in quiet were retrospectively obtained from the clinical record. Ten parents completed a questionnaire regarding their children's ease of communication and understanding in background noise.
Unaided performance in quiet was correlated with aided performance in competing noise, but not in two-talker speech. Only results in the two-talker masker were correlated with parental reports of their children's functional hearing abilities.
Speech perception testing in a complex background such as two-talker speech may provide a more accurate predictor of the communication challenges of children with hearing loss than testing in steady noise or quiet.
本研究检验了这样一个假设，即对于听力损失儿童而言，在复杂的双说话者掩蔽环境中的单词识别与现实世界中的言语感知之间的关联，比在安静环境或稳态噪声中进行的测试更为紧密。
对16名学龄期助听器使用者进行了噪声或双说话者言语环境下的助听单词识别测试。从临床记录中回顾性获取安静环境下言语感知的未助听估计值。10名家长完成了一份关于他们孩子在背景噪声中沟通和理解难易程度的问卷。
安静环境下的未助听表现与竞争噪声环境下的助听表现相关，但与双说话者言语环境下的助听表现无关。只有双说话者掩蔽环境下的结果与家长对其孩子功能性听力能力的报告相关。
与在稳态噪声或安静环境中进行测试相比，在诸如双说话者言语这样的复杂背景下进行言语感知测试，可能会为听力损失儿童的沟通挑战提供更准确的预测指标。
