The main objective was to develop and validate a MATLAB-based Competing Sentence Test (CST-K) and obtain preliminary normative data for this test within a small cohort of children aged 8 to 12.
This study comprised two phases. Phase 1 involved developing and validating the Competing Sentence Test in Kannada (CST-K). Sentences were selected from Kannada academic textbooks of III and IV standards, recorded by a male native Kannada speaker, and evaluated by three experienced audiologists. Phase 2, which includes normative pilot estimation, was conducted on 60 right-handed children aged 8-12 without hearing difficulties. The CST-K was administered in a quiet room in the school, where the noise level ranged from 40.3 to 43.2 dBA using a laptop and soundcard, presenting thirty pairs of simple sentences with a signal-to-competition ratio of -15 dB. Test-retest reliability was assessed after three weeks. Participants were evenly distributed among four age groups: 8-8.11 years, 9-9.11 years, 10-10.11 years, and 11-11.11 years.
The results indicated a significant difference between the scores obtained for the right and left ears. There was also a statistically significant difference across the age groups. The test-retest reliability test showed excellent reliability for the right ear and good reliability for the left ear scores.
A MATLAB-based Competing Sentence Test in Kannada Language was developed and validated in a recent study. The study found that scores were higher for the right ear and there was a significant age-related difference. This test can be used to evaluate binaural separation skills in Kannada-speaking children and can be included in the test battery. The study also provides normative data for the competing sentence test, which is reliable, making it a unique tool for clinicians to assess various clinical populations.
主要目的是开发和验证一个基于 MATLAB 的竞争句子测试（CST-K），并在一个 8 至 12 岁的儿童小队列中获得该测试的初步规范数据。
这项研究包括两个阶段。第一阶段涉及开发和验证 Kannada 语的竞争句子测试（CST-K）。句子选自 III 和 IV 标准的 Kannada 学术课本，由一名母语为 Kannada 的男性录制，并由三名经验丰富的听力学家进行评估。第二阶段包括规范初步估计，在 60 名没有听力困难的右撇子 8-12 岁儿童中进行。CST-K 在学校的安静房间中进行，使用笔记本电脑和声卡，噪声水平在 40.3 到 43.2 dBA 之间，呈现 30 对简单句子，信号与竞争比为-15 dB。三周后进行测试重测信度评估。参与者平均分布在四个年龄组中：8-8.11 岁、9-9.11 岁、10-10.11 岁和 11-11.11 岁。
结果表明，右耳和左耳的得分之间存在显著差异。年龄组之间也存在统计学上的显著差异。测试重测信度测试显示右耳具有极好的可靠性，左耳得分具有良好的可靠性。
最近的一项研究开发和验证了一种基于 Kannada 语的竞争句子测试的 MATLAB 版本。研究发现，右耳得分较高，并且存在与年龄相关的显著差异。该测试可用于评估 Kannada 语儿童的双耳分离技能，并可包含在测试组合中。该研究还提供了竞争句子测试的规范数据，该测试具有可靠性，使其成为评估各种临床人群的独特工具。
