有效的助听器（HA）康复需要HA适配参数的个性化，但在当前的临床实践中，通常仅个性化增益处方。为了优化验配过程，还可以针对个人听力缺陷定制高级HA设置，如降噪和麦克风方向性。在两个早期的研究中，听觉测试电池和数据驱动的方法，允许分类听力受损的听众到四个听觉配置文件的开发。由于发现这些简档的特征在于显著不同的听力能力，因此假设更定制的HA配件将为这些听众带来更好的结果。在这里，我们探讨了四个听觉配置文件和HA结果之间的潜在相互作用，评估与三种不同的措施（语音识别，整体质量和噪音烦恼）和六个HA处理策略与各种降噪，方向性和压缩设置。利用虚拟声学技术，模拟了一个真实的噪声中的语音环境。使用HA模拟器产生的刺激，并提交给49个习惯HA用户谁以前被剖析。四个听觉配置文件明显不同，其平均辅助语音接收阈值，从而意味着不同的需要，在信噪比的改善。然而，没有明确的相互作用与测试的HA处理strategies被发现。总体而言，这些研究结果表明，听觉配置文件可以捕捉一些HA处理需求的个体差异，需要进一步的研究，以确定合适的HA解决方案。
Effective hearing aid (HA) rehabilitation requires personalization of the HA fitting parameters, but in current clinical practice only the gain prescription is typically individualized. To optimize the fitting process, advanced HA settings such as noise reduction and microphone directionality can also be tailored to individual hearing deficits. In two earlier studies, an auditory test battery and a data-driven approach that allow classifying hearing-impaired listeners into four auditory profiles were developed. Because these profiles were found to be characterized by markedly different hearing abilities, it was hypothesized that more tailored HA fittings would lead to better outcomes for such listeners. Here, we explored potential interactions between the four auditory profiles and HA outcome as assessed with three different measures (speech recognition, overall quality, and noise annoyance) and six HA processing strategies with various noise reduction, directionality, and compression settings. Using virtual acoustics, a realistic speech-in-noise environment was simulated. The stimuli were generated using a HA simulator and presented to 49 habitual HA users who had previously been profiled. The four auditory profiles differed clearly in terms of their mean aided speech reception thresholds, thereby implying different needs in terms of signal-to-noise ratio improvement. However, no clear interactions with the tested HA processing strategies were found. Overall, these findings suggest that the auditory profiles can capture some of the individual differences in HA processing needs and that further research is required to identify suitable HA solutions for them.
