This study examined the effects of consistent hearing aid (HA) use on outcomes in children with mild hearing loss (HL).
Five- or 7-year-old children with mild HL were separated into 3 groups on the basis of patterns of daily HA use. Using analyses of variance, we compared outcomes between groups on speech and language tests and a speech perception in noise task. Regression models were used to investigate the influence of cumulative auditory experience (audibility, early intervention, HA use) on outcomes.
Full-time HA users demonstrated significantly higher scores on vocabulary and grammar measures compared with nonusers. There were no significant differences between the 3 groups on articulation or speech perception measures. After controlling for the variance in age at confirmation of HL, level of audibility, and enrollment in early intervention, only amount of daily HA use was a significant predictor of grammar and vocabulary.
The current results provide evidence that children's language development benefits from consistent HA use. Nonusers are at risk in areas such as vocabulary and grammar compared with other children with mild HL who wear HAs regularly. Service providers should work collaboratively to encourage consistent HA use.
本研究探讨持续使用助听器(HA)对轻度听力损失(HL)儿童各项指标的影响。
根据每日使用HA的模式,将5岁或7岁的轻度HL儿童分为3组。通过方差分析,我们比较了各组在言语和语言测试以及噪声中的言语感知任务方面的指标。使用回归模型研究累积听觉经验(可听度、早期干预、HA使用)对各项指标的影响。
与未使用者相比,全职HA使用者在词汇和语法测试中得分显著更高。3组在清晰度或言语感知指标上没有显著差异。在控制了HL确诊时的年龄差异、可听度水平和早期干预参与情况后,只有每日HA的使用量是语法和词汇的显著预测因素。
目前的结果表明,儿童的语言发展受益于持续使用HA。与其他定期佩戴HA的轻度HL儿童相比,未使用者在词汇和语法等方面存在风险。服务提供者应共同努力,鼓励持续使用HA。
