DESCRIPTION (provided by applicant): Some 25% of adults snore habitually, creating secondhand problems for those trying to sleep nearby (bed partners), frequently including chronic sleep deprivation. Sleep deprivation can impose a significant burden on health, cognition, driving ability, and social relationships. In the proposed Phase I effort, we will conduct a proof of concept (POC) test of technology for unobtrusively canceling the sound of snoring at the ears of a bed partner while permitting natural hearing of other sounds. The POC effort will comprise; 1) assembling a test system, 2) determining an adaptive situational transfer function, 3) quantifying real-time snore canceling performance of the Phase I device and algorithm and investigating sensor fusion enabling multi-transducer embodiments, and 4) working with our academic collaborator to secure IRB approval for Phase II activities involving human subjects. In Phase II, a device will be developed having consumer and sleep research applications. By selectively canceling snoring sounds, the envisioned device will enable a bed partner to sleep more and more peacefully. The envisioned device also is the basis for a new sleep research tool to study the impact of secondhand effects of snoring, as well as automating and simplifying the gathering and analyzing of breathing sound and other data useful in sleep research.

描述（由申请人提供）：大约25%的成年人习惯性地打鼾，给那些试图睡在附近的人（床伴）造成二手问题，经常包括慢性睡眠剥夺。睡眠不足会对健康、认知、驾驶能力和社会关系造成重大负担。在拟议的第一阶段工作中，我们将进行一项概念验证（POC）技术测试，以在不明显的情况下消除床伴耳边的鼾声，同时允许自然听到其他声音。POC工作将包括：1)组装测试系统，2)确定自适应情景传递函数，3)量化第一阶段设备和算法的实时降噪性能，并研究传感器融合实现多传感器实施例，以及4)与我们的学术合作者合作，确保涉及人类受试者的第二阶段活动获得IRB批准。在第二阶段，将开发一种具有消费者和睡眠研究应用的设备。通过选择性地消除打鼾的声音，这个设想中的设备将使与你同床的人睡得越来越安稳。这一设想中的设备也将成为一种新的睡眠研究工具的基础，用于研究打鼾的二手影响，以及自动化和简化呼吸声音和睡眠研究中有用的其他数据的收集和分析。
