Abstract

Purpose: The effectiveness of a dedicated bimodal hearing aid and fitting formula was investigated in pediatric cochlear implant recipients who were experienced Desired Sensation Level (DSL) v5.0 users.

Method: In Experiment 1, five children assessed four hearing aid fittings based on combinations of fitting formula (Adaptive Phonak Digital Bimodal [APDB], DSL v5.0, APDB fit to DSL v5.0 targets), hearing aid type (dedicated hearing aid for bimodal listeners, independent hearing aid), and/or prescriptive targets. Speech recognition scores were obtained in a sound booth in quiet and in noise. In Experiment 2, two participants from Experiment 1 were retested with an updated bimodal system.

Results: Bimodal speech recognition in quiet in both experiments was similar across all fitting formulas. In Experiment 1, bimodal speech recognition in noise was similar across fitting formulas; however, both in noise and in quiet, individual differences were observed. In Experiment 2, optimized APDB improved speech recognition in noise performance compared to APDB and similar performance compared to DSL v5.0 in a small set of bimodal listeners.

Conclusion: Preliminary results point to the value of individualized selection of hearing aid fitting formula settings for pediatric bimodal recipients.

研究儿童的双峰拟合方法。

目的：研究一种专用的双峰式助听器和配合器配方在儿童人工耳蜗受者中使用的有效性，这些受者都是期望感觉水平（DSL） v5.0用户。方法：在实验1中，五名儿童根据配装公式（自适应峰力数字双峰[APDB]， DSL v5.0， APDB适合DSL v5.0目标），助听器类型（专用助听器用于双峰听众，独立助听器）和/或规定目标的组合评估了四种助听器配件。在安静和噪音条件下，在音箱中获得语音识别分数。在实验2中，来自实验1的两名参与者使用更新的双峰系统重新测试。结果：在所有拟合公式中，两个实验在安静情况下的双峰语音识别是相似的。在实验1中，噪声下的双峰语音识别在拟合公式上是相似的；然而，无论是在噪音中还是在安静中，都观察到个体差异。在实验2中，与APDB相比，优化后的APDB在噪声性能方面提高了语音识别，在一小组双峰侦听器中，与DSL v5.0相比，APDB的性能也有所提高。结论：初步结果指出了个性化选择儿童双模受者助听器配戴配方设置的价值。

期刊介绍： Mission: AJA publishes peer-reviewed research and other scholarly articles pertaining to clinical audiology methods and issues, and serves as an outlet for discussion of related professional and educational issues and ideas. The journal is an international outlet for research on clinical research pertaining to screening, diagnosis, management and outcomes of hearing and balance disorders as well as the etiologies and characteristics of these disorders. The clinical orientation of the journal allows for the publication of reports on audiology as implemented nationally and internationally, including novel clinical procedures, approaches, and cases. AJA seeks to advance evidence-based practice by disseminating the results of new studies as well as providing a forum for critical reviews and meta-analyses of previously published work. Scope: The broad field of clinical audiology, including audiologic/aural rehabilitation; balance and balance disorders; cultural and linguistic diversity; detection, diagnosis, prevention, habilitation, rehabilitation, and monitoring of hearing loss; hearing aids, cochlear implants, and hearing-assistive technology; hearing disorders; lifespan perspectives on auditory function; speech perception; and tinnitus.
