The traditional fitting method for cochlear implants (CI), the single-channel fitting (SCF), is effective but time-consuming. A fitting method that is significantly faster to perform, but provides at least equivalent speech understanding and subjective benefit would be of clinical usefulness. The study explored the ability of flat strategy-based fitting (FSBF) maps to fill this need.
Participants were 16 experienced CI users. They were fit with: SCF maps; the maps that the participants used in their everyday lives, called fine-tuned clinical (FTC) maps; and FSBF maps. The fittings were assessed objectively via speech understanding in noise, time needed to create the map, deviation from FTC map, and correlation between auditory response telemetry thresholds and normalized charge levels; and subjectively via spectral balance and hearing quality.
FSBF maps were significantly faster to generate. FTC maps provided the best subjective hearing quality. In all other assessments, no significant differences were found.
FSBF maps can save time and provide CI users with the same level of speech understanding in noise. Participants may have preferred the FTC maps that they were already acclimated to them. These results suggest that the FSBF method could be used in first-fittings or in challenging fitting situations, but subsequent fine-tuning is required in follow-up appointments to improve sound quality.
The FSBF method can be a useful and time-saving alternative fitting method in first-fittings or in challenging fitting situations.
传统的人工耳蜗（CI）适配方法，即单通道适配（SCF），虽然有效，但耗时。如果有一种适配方法能够显著加快速度，同时提供至少相当的言语理解和主观获益，那么它将具有临床应用价值。本研究旨在探讨基于平坦策略的适配（FSBF）图谱是否能够满足这一需求。
参与者为 16 名经验丰富的 CI 用户。他们接受了以下三种适配方法的测试：SCF 图谱、他们日常生活中使用的精细调整临床（FTC）图谱和 FSBF 图谱。通过言语理解测试、创建图谱所需的时间、与 FTC 图谱的偏差以及听觉反应遥测阈值和归一化电荷量之间的相关性来评估客观适配效果，并通过频谱平衡和听力质量来评估主观适配效果。
FSBF 图谱的生成速度明显更快。FTC 图谱提供了最佳的主观听力质量。在所有其他评估中，没有发现显著差异。
FSBF 图谱可以节省时间，并为 CI 用户提供相同水平的噪声下言语理解能力。参与者可能更喜欢他们已经适应的 FTC 图谱。这些结果表明，FSBF 方法可以用于初次适配或具有挑战性的适配情况，但在随访预约中需要进行后续微调，以改善音质。
FSBF 方法是一种在初次适配或具有挑战性的适配情况下节省时间且有效的替代适配方法。
