| Abstract (English): | Background: Speech reception thresholds (SRTs) can be estimated with speech in noise tests using adaptive procedures. Since these tests are time-consuming, it is preferable to use as few trials as possible to identify reliable results. Aims/Objectives: To estimate the impact of early test termination in a German matrix speech test in noise (Oldenburger Satztest) on SRT estimation after 20 instead of after 30 sentences and to identify groups of subjects, for who such a tradeoff between measurement time and accuracy might be useful and acceptable. Material and methods: Retrospective analysis of 789 tests from cochlear implant users and from simulated tests in 10000 virtual subjects. Results: Early test termination results in increased estimation errors of the SRT in both real, and simulated listeners. Average test time is reduced from 5.0 to 3.6 min. For estimated SRT's above approximately +2 dB after 20 test sentences, the expected average difference to the result after 30 trials becomes higher than 0.5 dB. Conclusions and significance: If adaptive speech in noise tests are terminated already after 20 sentences, time can be saved, but it should be considered only in listeners with relatively favourable SRT-estimates after 20 trials, preferably below +2 dB.

| Abstract (Chinese): | 语音接收阈值(SRT)可以通过使用适应性程序进行的噪声测试中的语音来估计。由于这些测试很耗时, 因此最好使用尽可能少的试验来确定可靠的结果。 评估噪声中德语矩阵语音测试的早测试终止(Oldenburger Satztest)对20个句子后而不是30个句子后的SRT估计的影响, 并识别这样的受试者组群, 对他们来说在测量时间和准确性之间进行权衡可能是有用的且可接受的。 回顾性分析人工耳蜗植入者的789次测试的结果以及对10000名虚拟受试者进行的模拟测试。 早终止测试会导致实际和模拟听者的SRT的估计误差增加。平均测试时间从5.0分钟缩短到3.6分钟。对于20个测试句子后估计的SRT高于约+2dB, 30次测试后与该结果的预期平均差将高于0.5dB。 如果噪声中适应语音测试在20个句子后就终止, 是可以节省时间, 但只有对在20次试验后SRT估计相对较好的听者才能考虑这样做, 最好低于+2dB。 [ABSTRACT FROM AUTHOR] |
