This paper reports on the effect of age at fitting of hearing aids on subsequent achievements in speech intelligibility among hearing-impaired children. Four groups of hearing-impaired children were included in this investigation. Group A (n = 32) started using hearing aids in their first 6 months of life; Group B (n = 32) in their second 6 months of life; Group C (n = 38) in their second year of life and Group D (n = 51) in their third year of life. The children in each group were matched with regard to age, sex, age at onset of deafness, degree of hearing loss and educational establishment attended. The speech intelligibility of each child was rated by his/her class teacher on a 7-point scale. It was found that the speech intelligibility of the children in Group A was significantly superior to the speech intelligibility of the children in the other three groups. All other differences in speech intelligibility obtained between groups (Group B v. Group C v. Group D) were small and none proved to be statistically significant.
本文报告了助听器佩戴年龄对听力受损儿童后续言语清晰度成绩的影响。本调查纳入了四组听力受损儿童。A组（n = 32）在出生后的前6个月开始使用助听器；B组（n = 32）在出生后的第二个6个月开始使用；C组（n = 38）在1岁时开始使用，D组（n = 51）在2岁时开始使用。每组儿童在年龄、性别、耳聋 onset 年龄、听力损失程度和就读的教育机构方面进行了匹配。每个孩子的言语清晰度由其班主任以7分制进行评分。结果发现，A组儿童的言语清晰度明显优于其他三组儿童。其他组间（B组对C组对D组）在言语清晰度上的差异较小，且均未证明具有统计学意义。
