Abstract

Background: Although hearing aids (HAs) can compensate for reduced audibility, functional outcomes and benefits vary widely across individuals. As part of the Danish ‘Better hEAring Rehabilitation’ (BEAR) project, four distinct auditory profiles differing in terms of audiometric thresholds and supra-threshold hearing abilities were recently identified. Additionally, profile-specific HA-fitting strategies were proposed. The aim of the current study was to evaluate the self-reported benefit of these profile-based HA fittings in a group of new HA users. Methods: A total of 205 hearing-impaired older adults were recruited from two Danish university hospitals. Participants were randomly allocated to one of two treatment groups: (1) NAL-NL2 gain prescription combined with default advanced feature settings (‘reference fitting’) or (2) auditory profile-based fitting with tailored gain prescription and advanced feature settings (‘BEAR fitting’). Two months after treatment, the participants completed the benefit version of the short form of the Speech, Spatial, and Qualities of Hearing Scale (SSQ12-B) and the International Outcome Inventory for Hearing Aids (IOI-HA) questionnaire. Results: Overall, participants reported a clear benefit from HA treatment. However, no significant differences in the SSQ12-B or IOI-HA scores between the reference and BEAR fittings were found. Conclusion: First-time users experience clear benefits from HA treatment. Auditory profile-based HA fitting warrants further investigation.

基于听觉曲线的助听器验配：首次佩戴助听器者的自述收益

背景：虽然助听器（HA）可以补偿听力下降，但不同个体的功能结果和益处却大不相同。作为丹麦 "更好的听力康复"（BEAR）项目的一部分，最近确定了四种不同的听觉特征，它们在测听阈值和阈上听力能力方面各不相同。此外，还提出了针对不同特征的 HA 配戴策略。本研究的目的是评估这些基于听觉特征的助听器配戴方法对一组助听器新用户的自我感觉益处。研究方法：从丹麦两所大学医院共招募了 205 名听力受损的老年人。参与者被随机分配到两个治疗组中的一个：(1) NAL-NL2 增益处方结合默认高级功能设置（"参考验配"）或 (2) 基于听觉轮廓的验配，包括量身定制的增益处方和高级功能设置（"BEAR 验配"）。治疗两个月后，受试者完成受益版言语、空间和听力质量量表（SSQ12-B）简表和国际助听器结果量表（IOI-HA）问卷。结果：总体而言，参与者均表示从 HA 治疗中明显受益。然而，在 SSQ12-B 或 IOI-HA 分数上，参考配戴者和 BEAR 配戴者之间没有发现明显的差异。结论：首次使用者可从 HA 治疗中明显受益。基于听觉曲线的 HA 佩戴方法值得进一步研究。

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
