头枕扬声器提升车载沉浸式音频体验
Evaluation of Headrest-Integrated Loudspeakers for Enhanced Spatial Audio Immersion in Automotive Cabins
- 用头枕内置扬声器构建个人声场，减少干扰
- 主观测试显示用户偏好度显著提升
- 适合追求高品质车载音响的用户
沉浸式对象化空间音频已成为音乐产业制作、分发和播放的标准。越来越多汽车开始集成此类内容以提供高端娱乐体验，推动了新型音频渲染技术的发展。尽管头枕集成扬声器已有50多年历史，但尚未成为新车标配。它们能通过创建个人声区有效减少乘客干扰，同时补充现有舱内扬声器，显著提升沉浸感。我们通过成对比较实验进行主观评估，测量用户对音质与空间属性的偏好，并采用概率选择模型（Bradley-Terry-Luce）建模结果。结果显示，头枕集成扬声器在沉浸式音频场景中可显著改善听觉感知。
原文摘要 · Abstract (English)
Immersive object-based spatial audio is now firmly established in the music industry as the standard for production, distribution, and playback. The number of automobiles integrating such content to provide premium entertainment experiences is steadily increasing, driving the development of new audio rendering techniques. While loudspeakers integrated into automotive headrests have been around for more than 50 years, they have not yet achieved status as a standard feature in new cars. However, they represent a powerful tool for reproducing immersive audio by enabling the creation of personal sound zones with reduced passenger distraction while effectively complementing existing cabin speakers. We conducted subjective assessments using paired comparison experiments to measure preference and multiple spatial audio attributes. We modeled the resulting probability outcomes using a probabilistic choice model, the Bradley-Terry-Luce rank ordering. The results indicate that headrest-integrated speakers can improve the audio perception in immersive audio scenarios.
