This study examined the accuracy of hearing aid output to DSL v5.0 Child targets in a group of children who wear hearing aids, and the impact on their auditory outcomes.
For each participant, the output of the initial hearing aid fitting was compared to DSL v5.0 Child prescriptive targets and again after the fitting was adjusted using coupler-based verification and RECD measures. Outcomes for initial and adjusted fittings were examined using the Speech Intelligibility Index (SII), Parent's Evaluation of Aural/Oral Performance of Children (PEACH) rating scale, and speech perception tests in quiet and noise.
Sixty-eight children aged 3 months to 17 years with moderate to profound hearing loss participated in the study.
Fit-to-targets improved significantly after hearing aids were adjusted to match targets to within 5 dB RMSE. Adjusted hearing aids provided increased aided audibility compared to initial fittings and resulted in improved speech perception scores and parent-reported hearing performance. Fifty percent of the children aged 6 to 17 years preferred their adjusted fitting compared to 10% who preferred their initial fitting.
Improvement in fit-to-target to a validated paediatric prescriptive formula using best practice procedures can result in improved auditory outcomes and possible self-reported satisfaction.
本研究考察了一组佩戴助听器的儿童的助听器输出与 DSL v5.0 儿童目标的准确性，以及对其听觉结果的影响。
对于每个参与者，初始助听器适配的输出与 DSL v5.0 儿童规定目标进行了比较，然后使用基于耦合器的验证和 RECD 测量值对适配进行调整后再次进行了比较。使用言语可懂度指数（SII）、父母对儿童听觉/口语表现的评估（PEACH）评分量表以及安静和噪声环境下的言语感知测试，对初始和调整后的适配进行了评估。
68 名年龄在 3 个月至 17 岁之间、有中度至重度听力损失的儿童参与了这项研究。
助听器调整至目标匹配范围内 5dB RMSE 后，与目标的匹配度显著提高。与初始适配相比，调整后的助听器提供了更高的助听可听度，从而提高了言语感知得分和家长报告的听力表现。与 10%更喜欢初始适配的儿童相比，6 至 17 岁的儿童中有 50%更喜欢调整后的适配。
使用最佳实践程序使目标匹配度达到经过验证的儿科规定公式的改进可以带来更好的听觉结果和可能的自我报告满意度。
