目的本研究调查了NAL-NL 2算法为老年听力损失患者规定的常见真耳辅助反应（REAR）配置。方法根据934名成年人的听力测定数据构建了一个代表美国老年轻度至中度感音神经性听力损失人群的数据集（年龄55-85岁）来自1999-2012年国家健康与营养检查调查。实现了两种聚类方法，以在三个输入电平（55、65和75 dB SPL）下为八个频率（0.25、0.5、1、2、3、4、6和8 kHz）生成常见的REAR配置。(a)在基于REAR的聚类方法中，首先将国家健康和营养检查调查听力图转换为REAR目标，然后聚类以生成常见的REAR配置。(b)在基于听觉图的聚类方法中，首先将听觉图聚类为常见的听力损失简档，然后将其转换为REAR配置。可用REAR配置的数量与听力损失可以通过其中至少一种配置来拟合的美国人口的百分比之间的权衡（即，覆盖率）进行了评价。听力损失匹配被定义为个人的REAR目标与集群REAR配置之间的差异小于± 5-dB。结果覆盖百分比随着可用REAR配置的数量而增加，四种配置可覆盖75%的人口。总体而言，基于REAR的聚类产生了5个百分点更好的覆盖率平均相比，基于audiogram-based clustering.ConclusionsThe常见的REAR配置可用于编程的增益频率响应在预先配置的柜台助听器，并提供临床适当的放大设置为老年人轻度至中度听力损失。
PurposeThis study investigates common real-ear aided response (REAR) configurations prescribed by the NAL-NL2 algorithm for older adults with hearing loss.MethodA data set that is representative of the older adult U.S. population with mild-to-moderate sensorineural hearing loss was constructed from the audiometric data of 934 adults (aged 55–85 years) from the National Health and Nutrition Examination Survey years 1999–2012. Two clustering approaches were implemented to generate common REAR configurations for eight frequencies (0.25, 0.5, 1, 2, 3, 4, 6, and 8 kHz) at three input levels (55, 65, and 75 dB SPL). (a) In the REAR-based clustering approach, the National Health and Nutrition Examination Survey audiograms were first converted to REAR targets and then clustered to generate common REAR configurations. (b) In the audiogram-based clustering approach, the audiograms were first clustered into common hearing loss profiles and then converted to REAR configurations. The trade-off between the number of available REAR configurations and the percentage of the U.S. population whose hearing loss could be fit by at least one of them (i.e., percent coverage) was evaluated. Hearing loss fit was defined as less than ± 5-dB difference between an individual's REAR targets and those of the clustered REAR configuration.ResultsPercent coverage increases with the number of available REAR configurations, with four configurations resulting in 75% population coverage. Overall, REAR-based clustering yielded 5 percentage points better coverage on average compared to audiogram-based clustering.ConclusionsThe common REAR configurations can be used for programming the gain frequency responses in preconfigured over-the-counter hearing aids and provide clinically appropriate amplification settings for older adults with mild-to-moderate hearing loss.
