研究通过结合对330名成年人的调查及90人多年耳机音频暴露记录，刻画野外个人听力设备使用情况，发现使用呈间歇性，与心理特征有关联，为可穿戴计算在佩戴期望、情境覆盖、安全干预及个性化方面提供启示。
AI 中文摘要
耳戴式设备正从音频播放工具演变为用于健康、交互和情境感知的传感平台。然而，可穿戴系统的设计和评估通常基于对人们实际佩戴个人听力设备（PLD）的时长、频率和场景的强烈假设。为了使这些假设基于野外行为，我们将对330名成年人的调查与其中90人通过苹果健康捐赠的多年被动记录的耳机音频暴露记录相结合。我们刻画了人们使用PLD的地点和时间、近年来记录的使用情况如何变化，以及心理特征和社会背景与PLD使用的关联。结果显示，记录的平均每日使用时间从2020年的37分钟增加到2024年的64分钟。听力是间歇性的：2024年48%的参与者日没有记录到听力，周末的会话次数少但时间长。感觉寻求，特别是去抑制，与自我报告的PLD使用呈小到中等程度的正相关。年轻人的收听音量高于25 - 34岁组。高音量暴露不常见，只有4%的参与者周超过世界卫生组织（WHO）的安全听力限制。最后，大多数参与者还报告在社交场合避免使用PLD。我们将这些发现转化为对可穿戴计算的启示：对间歇性而非持续性佩戴的现实期望、预期系统间隙的情境覆盖、有针对性的安全听力干预，以及基于心理社会和人口统计学特征而非统一使用假设的个性化。
英文摘要
Ear-worn devices are evolving from audio-playback tools into sensing platforms for health, interaction, and context-awareness. Yet, earable systems are typically designed and evaluated under strong assumptions about how long, how often, and in which situations people actually wear personal listening devices (PLDs). To ground these assumptions in-the-wild behavior, we combine a survey of 330 adults with multi-year, passively logged headphone audio-exposure records donated via Apple Health by 90 of them. We characterize where and when people use PLDs, how logged use has changed in recent years, and how psychological traits and social context associate with PLD usage. Our results show that logged mean daily use has increased from 37 minutes in 2020 to 64 minutes in 2024. Listening was intermittent: no listening was logged on 48% of participant-days in 2024, and sessions were fewer but longer on weekends. Sensation seeking, particularly disinhibition, showed small to medium positive associations with self-reported PLD use. Younger adults listened at higher volumes than the 25-34 group. High-volume exposure was uncommon, with only 4% of participant-weeks exceeding World Health Organization (WHO) safe-listening limits. Finally, most participants also reported avoiding PLD use in social situations. We translate these findings into implications for earable computing: realistic expectations of intermittent rather than continuous wear, contextual coverage that anticipates systematic gaps, targeted safe-listening interventions, and personalization grounded in psychosocial and demographic profiles rather than assumptions of uniform use.
