目的：本研究的目的是 (1) 检查词汇和年龄对正常听力 (NH) 儿童在噪音中的单词识别的影响，以及 (2) 比较噪音中和安静听力条件下的单词识别表现。 方法：参与者为 213 名 NH 儿童（年龄在 3 至 6 岁之间）。 89 名参与者和 124 名参与者分别在噪音和安静的聆听条件下进行了测试。标准汉语词汇邻域测试包含四个词汇类别（即双音节易（DE）、双音节难（DH）、单音节易（ME）和单音节难（MH））的单词列表，用于评估信噪比（SNR）为0 dB的语音谱形噪声（SSN）中的普通话中文单词识别。采用双向重复测量方差分析来考察以音节长度和难度水平为主要影响因素的安静和噪声听力条件下单词识别的词汇效应。使用回归模型检验年龄对单词识别性能的影响。结果：噪声中的单词识别性能显着低于安静中的单词识别性能，并且噪声中单词识别性能的个体差异远大于安静中的个体差异。单词识别分数表明词汇效应在 SSN 中显着。儿童对双音节单词的得分高于对单音节单词的得分；在噪声条件下，“简单”的单词得分高于“困难”的单词。 NH 儿童在 SSN（SNR = 0 dB）中 DE、DH、ME 和 MH 单词的得分分别为 85.4、65.9、71.7 和 46.2%。在噪声中测试的NH儿童在每个词汇类别中的单词识别性能也随着年龄的增长而提高。结论：年龄和单词的词汇特征对噪声中普通话单词识别的性能有显着影响。词汇效应在噪音聆听条件下比在安静条件下更明显。 3-6岁的NH儿童在噪音中的单词识别表现随着年龄的增长而增加，并且在NH儿童的6岁时还没有达到稳定水平。 (C) 2015 年，爱思唯尔爱尔兰有限公司出版。
Objectives: The purposes of the present study were (1) to examine the lexical and age effects on word recognition of normal-hearing (NH) children in noise, and (2) to compare the word-recognition performance in noise to that in quiet listening conditions.Methods: Participants were 213 NH children (age ranged between 3 and 6 years old). Eighty-nine and 124 of the participants were tested in noise and quiet listening conditions, respectively. The Standard-Chinese Lexical Neighborhood Test, which contains lists of words in four lexical categories (i.e., dissyllablic easy (DE), dissyllablic hard (DH), monosyllable easy (ME), and monosyllable hard (MH)) was used to evaluate the Mandarin Chinese word recognition in speech spectrum-shaped noise (SSN) with a signal-to-noise ratio (SNR) of 0 dB. A two-way repeated-measures analysis of variance was conducted to examine the lexical effects with syllable length and difficulty level as the main factors on word recognition in the quiet and noise listening conditions. The effects of age on word-recognition performance were examined using a regression model.Results: The word-recognition performance in noise was significantly poorer than that in quiet and the individual variations in performance in noise were much greater than those in quiet. Word recognition scores showed that the lexical effects were significant in the SSN. Children scored higher with dissyllabic words than with monosyllabic words; "easy" words scored higher than "hard" words in the noise condition. The scores of the NH children in the SSN (SNR = 0 dB) for the DE, DH, ME, and MH words were 85.4, 65.9, 71.7, and 46.2% correct, respectively. The word-recognition performance also increased with age in each lexical category for the NH children tested in noise.Conclusions: Both age and lexical characteristics of words had significant influences on the performance of Mandarin-Chinese word recognition in noise. The lexical effects were more obvious under noise listening conditions than in quiet. The word-recognition performance in noise increased with age in NH children of 3-6 years old and had not reached plateau at 6 years of age in the NH children.
