The increased demand for well-being has fueled interest in sleep. Research in technology for monitoring sleep ranges from sleep efficiency and sleep stage analysis to sleep disorder detection, centering on wearable devices such as fitness bands, and some techniques have been commercialized and are available to consumers. Recently, as interest in digital therapeutics has increased, the field of sleep engineering demands a technology that helps people obtain quality sleep that goes beyond the level of monitoring. In particular, interest in sleep aids for people with or without insomnia but who cannot fall asleep easily at night is increasing. In this review, we discuss experiments that have tested the sleep-inducing effects of various auditory stimuli currently used for sleep-inducing purposes. The auditory stimulations were divided into (1) colored noises such as white noise and pink noise, (2) autonomous sensory meridian response sounds such as natural sounds such as rain and firewood burning, sounds of whispers, or rubbing various objects with a brush, and (3) classical music or a preferred type of music. For now, the current clinical method of receiving drugs or cognitive behavioral therapy to induce sleep is expected to dominate. However, it is anticipated that devices or applications with proven ability to induce sleep clinically will begin to appear outside the hospital environment in everyday life.
对健康的需求增加激发了人们对睡眠的兴趣。监测睡眠的技术研究范围从睡眠效率和睡眠阶段分析到睡眠障碍检测，主要集中在可穿戴设备上，如健身带，其中一些技术已经商业化，可供消费者使用。最近，随着人们对数字治疗的兴趣增加，睡眠工程领域需要一种能够帮助人们获得优质睡眠的技术，而不仅仅是监测睡眠。特别是，人们对那些有或没有失眠但晚上难以入睡的人的睡眠辅助工具的兴趣正在增加。在这篇综述中，我们讨论了目前用于诱导睡眠的各种听觉刺激的睡眠诱导效果的实验。听觉刺激分为 (1) 白噪声和粉红噪声等有色噪声，(2) 自主感觉经络反应声音，如雨声、柴火燃烧声、耳语声，或用刷子摩擦各种物体的声音，以及 (3) 古典音乐或喜欢的音乐类型。目前，接受药物或认知行为疗法诱导睡眠的临床方法预计仍将占主导地位。然而，预计具有临床证明的诱导睡眠能力的设备或应用程序将开始在日常生活中出现在医院环境之外。
