通过增强耳部声学特征，提升听障者对音乐乐器的分离能力。
Effects of HRTF Augmentation on Predicted Spatial Release from Masking in Music
- 用增强版头相关传递函数放大空间线索
- 模型显示乐器分离度显著提升，听损下仍有效但减弱
- 适合听力康复与音频处理研究者参考
在复杂声音混合中分离单个乐器对听障人群仍是重大挑战。尽管空间分离能改善语音识别，但空间线索增强对音乐感知的潜在益处尚未深入探索。本文提出一种通过增强个体头相关传递函数（HRTFs）来提高空间线索显著性的方法。听觉模型分析表明，相较于原始HRTFs，增强后的HRTFs可提升乐器间的可分离性。当模拟中度感音神经性听力损失时，预测效益依然存在，但大幅降低。仿真助听器处理未能将这些效益恢复至正常听力水平。
原文摘要 · Abstract (English)
Separating individual musical instruments within a complex mixture of sounds poses a persistent challenge for listeners with hearing loss. Although spatial separation of sources improves speech recognition in this population, the potential benefits of spatial cue enhancement for music perception remain largely unexplored. This paper introduces a method to increase spatial cue salience through the augmentation of individual head-related transfer functions (HRTFs). Auditory model analyses indicate that augmented HRTFs may enhance the separability of musical instruments relative to individual HRTFs. Predicted benefits persist when moderate sensorineural hearing loss is modelled, though they are substantially reduced. Simulated hearing aid processing does not restore these benefits to normal-hearing levels.
