Our recent work shows that high frequency energy in speech is important for the localisation of speech and may also aid in improving speech intelligibility in noisy environments. The work proposed here will systematically explore this somewhat surprising new finding and the results will be incorporated into a predictive model of speech intelligibility under spatial listening conditions. This work includes a systematic study of auditory functional plasticity to changes in the spatial cues. Taken together, the outcomes of this work will unlock a range of new approaches to enhancing spatial hearing in multi-channel communication devices and spatial hearing aids.

我们最近的工作表明，语音中的高频能量对语音的定位很重要，也可能有助于提高嘈杂环境下的语音清晰度。这里提出的工作将系统地探索这一令人惊讶的新发现，并将结果纳入空间听力条件下语音可理解性的预测模型。这项工作包括对空间线索变化的听觉功能可塑性的系统研究。综上所述，这项工作的结果将开启一系列新的方法来增强多通道通信设备和空间助听器的空间听力。
