Abstract

Background and objectives: This study aimed to develop and validate a modified version of the Speech in Noise Sentence Test in Kannada, which would be appropriate for testing the speech comprehension ability of children aged 8-12 years.

Subjects and methods: A total of 120 sentences were chosen from 200 familiar sentences and split into four lists. Continuous discourse was used as a competition or distractor. Using MATLAB, the target stimulus was presented at 0-degree azimuth while the distractor's location varied (+90° and -90° azimuth). The test was programmed to dynamically adjust the signal-to-noise ratio (SNR) based on participants' responses. After initial validation, a pilot study was conducted with 60 typically hearing children aged 8 to 12 years.

Results: The SNR50 scores significantly improved when the distractor and target sentences were spatially separated across all groups. Age had a significant influence on the spatial separation scores. The test-retest reliability was excellent.

Conclusions: The developed stimuli effectively measured spatial separation, and the normative and psychometric analyses demonstrated reliable outcomes.

坎纳达语空间隔离句子测试的开发与验证

背景和目的：......：本研究旨在开发和验证坎纳达语 "噪音中的语音句子测试 "的修订版，以测试 8-12 岁儿童的语音理解能力：从 200 个熟悉的句子中选出 120 个句子，分成四个列表。连续话语被用作竞争或干扰项。使用 MATLAB，目标刺激物在 0 度方位角呈现，而分心物的位置变化（+90 度和-90 度方位角）。测试程序根据参与者的反应动态调整信噪比（SNR）。经过初步验证后，对 60 名 8 至 12 岁的典型听力儿童进行了试点研究：当分心句子和目标句子在空间上分开时，各组的 SNR50 分数都有明显提高。年龄对空间分离得分有很大影响。结论：.....：结论：所开发的刺激能有效测量空间分隔能力，常模和心理测量分析表明结果可靠。

期刊介绍： Journal of Audiology and Otology (JAO) (formerly known as Korean Journal of Audiology) aims to publish the most advanced findings for all aspects of the auditory and vestibular system and diseases of the ear using state-of-the-art techniques and analyses. The journal covers recent trends related to the topics of audiology, otology, and neurotology conducted by professionals, with the goal of providing better possible treatment to people of all ages, from infants to the elderly, who suffer from auditory and/or vestibular disorders and thus, improving their quality of life. This journal encourages the submission of review papers about current professional issues, research papers presenting a scientific base and clinical application, and case papers with unique reports or clinical trials. We also invite letters to the editor and papers related to the manufacture and distribution of medical devices. This journal provides integrated views from otologists, audiologists, and other healthcare practitioners, offering readers high quality scientific and clinical information. This peer-reviewed and open access journal has been the official journal of the Korean Audiological Society since 1997 and of both the Korean Audiological Society and the Korean Otological Society since 2017. It is published in English four times a year in January, April, July, and October.
