To propose an instrument for assessing speech recognition in the presence of competing noise. To define its application strategy for use in clinical practice. To obtain evidence of criterion validity and present reference values.
The study was conducted in three stages: Organization of the material comprising the Word-with-Noise Test (Stage 1); Definition of the instrument's application strategy (Stage 2); Investigation of criterion validity and definition of reference values for the test (Stage 3) through the evaluation of 50 normal-hearing adult subjects and 12 subjects with hearing loss.
The Word-with-Noise Test consists of lists of monosyllabic and disyllabic words and speech spectrum noise (Stage 1). The application strategy for the test was defined as the determination of the Speech Recognition Threshold with a fixed noise level at 55 dBHL (Stage 2). Regarding criterion validity, the instrument demonstrated adequate ability to distinguish between normal-hearing subjects and subjects with hearing loss (Stage 3). Reference values for the test were established as cut-off points expressed in terms of signal-to-noise ratio: 1.47 dB for the monosyllabic stimulus and -2.02 dB for the disyllabic stimulus. Conclusion: The Word-with-Noise Test proved to be quick to administer and interpret, making it a useful tool in audiological clinical practice. Furthermore, it showed satisfactory evidence of criterion validity, with established reference values.
提出一种评估在噪声竞争环境下言语识别能力的仪器。定义其在临床实践中的应用策略。获得效标效度的证据并提供参考值。
研究分三个阶段进行：组成包含噪声测试词的材料的组织（第 1 阶段）；仪器应用策略的定义（第 2 阶段）；通过对 50 名正常听力成人和 12 名听力损失患者的评估，对效标效度和测试参考值的调查（第 3 阶段）。
噪声测试词由单音节词和双音节词列表和语音频谱噪声组成（第 1 阶段）。测试的应用策略定义为在 55dBHL 的固定噪声水平下确定言语识别阈值（第 2 阶段）。关于效标效度，该仪器在区分正常听力受试者和听力损失受试者方面表现出了足够的能力（第 3 阶段）。测试的参考值被确立为以信噪比表示的截断值：单音节刺激为 1.47dB，双音节刺激为-2.02dB。结论：噪声测试词被证明易于管理和解释，使其成为听力学临床实践中的有用工具。此外，它显示出令人满意的效标效度证据，具有既定的参考值。
