Abstract

The LOT test was administered to 100 normal-hearing subjects ranging in age from seven years, six months to 10 years, six months. The test was conducted at 500, 1000, 2000, and 4000 Hz with 99 subjects who were able to perform the required task. The LOT test misclassified (false-positive result) only 4% of the normal-hearing children at 1000 Hz. The test misclassified 3% at 2000 Hz, 3% at 4000 Hz, and 14% at 500 Hz. A new criterion for the use of the LOT test with children is proposed which reduced the percentage of misclassification to 2% at 1000, 2000, and 4000 Hz. The frequency of 500 Hz is not recommended for the preadolescent population.

摘要

对100名年龄在7岁6个月至10岁6个月之间的听力正常受试者进行了LOT测试。对99名能够完成所需任务的受试者在500、1000、2000和4000赫兹频率下进行了测试。在1000赫兹时，LOT测试仅将4%的听力正常儿童误分类（假阳性结果）。在2000赫兹时测试误分类率为3%，4000赫兹时为3%，500赫兹时为14%。提出了一项针对儿童使用LOT测试的新标准，该标准在1000、2000和4000赫兹时将误分类率降至2%。不建议对青春期前人群使用500赫兹频率。
