The broader impact/commercial potential of this PFI project is to increase the economic competitiveness of the United States in the carbon nanotube thermophone market, specifically beating other countries to market in the active noise control arena. Ventilation noise in hospitals is detrimental to patient recovery, in schools is detrimental to student learning outcomes, and in communities is detrimental to restful sleep leading to increased stress. This project develops a noise control product concept to significantly improve the welfare of the American people in these areas. In addition to the beachhead market of building ventilation, the technology has applications in the automotive and heavy equipment industries, and in military stealth applications, potentially protecting the lives of the American warfighter. This project will enhance a partnership between academia and industry, potentially launching a new start-up. This PFI-TT project will engage one graduate student and one post-graduate student in active entrepreneurship while supporting participation of women in science, engineering, and entrepreneurship. The proposed project will develop a prototype for a coaxial active noise cancelation device in ventilation ducts using carbon nanotube (CNT) thermophones. The technology provides an active silencer solution that allows the occupant to customize sound in real time, a unique market feature, with as much as an 80% size and weight reduction while improving air handler efficiency over current passive silencer technologies. The coaxial loudspeaker technology is enabled through carbon nanotechnology to create a compact speaker with no moving parts. The product is a drop-in replacement to existing duct systems and can be installed in line. Excessive noise from air handlers is detrimental in schools, theaters, hospitals, and in communities near industrial facilities. This technology aims to alleviate these noise burdens in an economical and safe way. The prototype developed under this program will be used to prove the technology to industry facility managers, value-added-resellers, and building engineers, who are historically risk-averse in adopting new technology. In particular, showing that the technology can be scaled to large ducts (6" in diameter or more), that the device does not increase system backpressure, and that it has significant lifespan with limited maintenance will be key outcomes from this work.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个PFI项目更广泛的影响/商业潜力是提高美国在碳纳米管热声器市场的经济竞争力，特别是在主动噪声控制竞技场市场上击败其他国家。医院的通风噪音不利于病人的康复，学校的通风噪音不利于学生的学习成果，社区的通风噪音不利于睡眠，导致压力增加。该项目开发了一种噪音控制产品概念，以显着改善这些地区美国人民的福利。除了建筑通风的滩头市场外，该技术还应用于汽车和重型设备行业，以及军事隐身应用，可能保护美国战士的生命。该项目将加强学术界和工业界之间的伙伴关系，可能会启动一个新的初创企业。该项目将使一名研究生和一名研究生积极创业，同时支持妇女参与科学、工程和创业。拟议的项目将开发一个原型的同轴有源噪声消除设备在通风管道使用碳纳米管（CNT）热电偶。该技术提供了一种主动消声器解决方案，允许乘员在真实的时间内定制声音，这是一种独特的市场功能，与当前被动消声器技术相比，尺寸和重量减少了80%，同时提高了空气处理器效率。同轴扬声器技术通过碳纳米技术实现，以创建没有移动部件的紧凑扬声器。该产品是现有管道系统的直接替代品，可以在线安装。空气处理器产生的过度噪音在学校、剧院、医院和工业设施附近的社区是有害的。这项技术旨在以经济和安全的方式减轻这些噪音负担。根据该计划开发的原型将用于向行业设施管理人员，增值经销商和建筑工程师证明该技术，这些人在采用新技术时历来不愿承担风险。特别是，该技术可以扩展到大型管道（直径6”或更大），该设备不会增加系统背压，并且在有限的维护下具有显著的使用寿命，这将是这项工作的关键成果。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
