An investigation was conducted to determine whether grammatical, semantical, and phonological constraints affect aural masking. The rationale centered around the non-representative and non-optimal characteristics of white noise as a masker. Also, prior conclusions that content and linguistic rules do not influence masking warranted examination. Six lists, each of 25 simultaneously competing message of 36 college-age, normal hearing, native speakers of English. The 6 classes of competing messages were forward grammatical strings, forward semantically anomalous strings, forward ungrammatical strings, and the same 3 sets reproduced backwards. Articulation scores computed in percentages served as measures. Performances when the forward semantically anomalous strings and the forward ungrammatical strings functioned as maskers were depressed relative to the other conditions and not significantly different from each other.
开展了一项调查，以确定语法、语义和语音限制是否会影响听觉掩蔽。其基本原理围绕白噪声作为掩蔽音的非代表性和非最优特性。此外，之前关于内容和语言规则不影响掩蔽的结论也值得检验。准备了六个列表，每个列表包含25个同时竞争的信息，由36名大学年龄、听力正常的英语母语者提供。六类竞争信息分别是正向语法字符串、正向语义异常字符串、正向不符合语法的字符串，以及这三组信息的反向重复。以百分比计算的清晰度得分作为衡量指标。当前向语义异常字符串和正向不符合语法的字符串用作掩蔽音时，表现相对于其他条件有所下降，且彼此之间没有显著差异。
