目得：本研究探讨了频率特定的声音和言语清晰度指数（SII）的关系，以言语感知能力的儿童感音神经性听力损失使用数字信号处理助听器与宽动态范围compression.METHOD：26名儿童年龄5-15岁的纯音平均值（0.5，1.0和2.0 kHz）从60-98分贝HL参加。根据每种助听器的压缩特性创建三个亚组。使用调频音的辅助阈值确定最小可听度，并使用助听器的模拟真耳输出在55和70 dB SPL下计算SII。词汇邻域测试（LNT; K。I.柯克，D。B。Pisoni，& M.结果：70 dB SPL组LNT评分明显高于50 dB SPL组。平均辅助阈值在0.5，1.0，和2.0 kHz呈负相关，在50 dB SPL的LNT分数，在55和70 dB SPL的SIIs与LNT分数呈正相关，在50和70 dB SPL。结论：结果支持使用辅助阈值和语音测试分数在软到响亮的水平作为放大拟合过程的一部分。
PURPOSE: This study examined the relation of audibility for frequency-specific sounds and the Speech Intelligibility Index (SII) to speech perception abilities of children with sensorineural hearing loss using digital signal-processing hearing aids with wide dynamic range compression.METHOD: Twenty-six children age 5-15 years with pure-tone averages (0.5, 1.0, and 2.0 kHz) from 60-98 dB HL participated. Three subgroups were created based on the compression characteristics of each hearing aid. Minimum audibility was determined using aided thresholds for frequency-modulated tones and the SII calculated at 55 and 70 dB SPL using the simulated real-ear output of the hearing aid. The Lexical Neighborhood Test (LNT; K. I. Kirk, D. B. Pisoni, & M. J. Osberger, 1995) was presented at 50 and 70 dB SPL.RESULTS: LNT scores at 70 dB SPL were significantly higher than at 50 dB SPL. Average aided thresholds at 0.5, 1.0, and 2.0 kHz were negatively correlated with LNT scores at 50 dB SPL, and SIIs at 55 and 70 dB SPL were positively correlated with LNT scores at 50 and 70 dB SPL.CONCLUSIONS: Results support using aided thresholds and speech test scores at soft to loud levels as part of the amplification fitting process.
