在复杂声音混合中分离单个乐器对听力损失患者而言是持续存在的挑战。尽管声源的空间分离可改善该群体的言语识别，但空间线索增强对音乐感知的潜在益处仍大多未被探索。本文提出一种通过增强个体头相关传输函数（HRTF）来提高空间线索显著性的方法。听觉模型分析表明，与个体HRTF相比，增强后的HRTF可提升乐器的可分离性；当模拟中度感音神经性听力损失时，该预测益处仍然存在但会大幅降低；模拟助听器处理无法将这些益处恢复至正常听力水平。
英文摘要
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.
