I-Corps: See-through Technology

这个i-Corps项目的更广泛的影响/商业潜力是开发技术，通过可视化声音和声源来控制噪音污染，无论它们在哪里。高剂量噪声暴露与高压力、高血压、言语干扰、听力损失、睡眠障碍等有直接联系。噪声缓解和控制是各级政府和行业的强制性要求。拟议的技术将在从源头解决各种噪音问题方面发挥关键作用，这是最具成本效益的方法。它适用于所有行业，从汽车、卡车、摩托车、火车、飞机等交通工具到吸尘器、洗碗机、洗衣机等以噪音为主要关注点的家用电器，它可以补充人工智能，增强机器人的视觉和听觉，以缓解噪音问题。这个i-Corps项目基于技术的发展，以确定复杂机器的噪音和振动的根本原因。它可以从根本上改变全息术、光学全息术、声全息术、近场声全息术、光声全息术等的概念，这些概念限制了全息术只能在均匀和均匀的介质中进行；它使人们能够无边界地可视化3D声场，因为声场的可视化可以跨不同的弹性介质进行。与其他专利算法一起，工程师可以查看所有振动声量，包括声压、声强、在任何频率下振动结构的操作挠度形状，可视化固体外壳后面和内部的激励力，建立声辐射和结构振动之间的相互关系，并以最具成本效益的方式缓解噪音和振动问题。使用这些创新技术，工程师将能够进行有针对性的噪音控制，在不增加复杂机器质量的情况下减少噪音排放，从而降低燃料消耗和总体成本。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this I-Corps project is the development of technology to control noise pollution by visualizing sound and sound sources wherever they may be. There is a direct link between high-dose noise exposure to the high stresses, high blood pressures, speech interferences, hearing losses, sleep disruptions, etc. Noise mitigation and control are mandatory requirements at all levels of governments and industries. The proposed technology will play a key role in tackling various noise issues at sources, which is the most cost-effective approach. It is applicable to all industries ranging from transportation such as cars, trucks, motorcycles, trains, aircrafts, etc. to household appliances such as vacuum cleaners, dishwashers, washing machines, etc. where noise is of a primary concern, and it can supplement artificial intelligence and enhance the visual and hearing senses of robots to mitigate noise issues.This I-Corps project is based on the development of technology to determine the root causes of noise and vibrations of complex machines. The proposed may fundamentally change the notions of holography, optical holography, acoustic holography, near-field acoustic holography, photo-acoustic holography, etc., which limit holography to be done in a homogeneous and uniform medium; and it enables one to visualize a 3D acoustic field without bounds because visualization of the sound field may be done across different elastic media. Together with other proprietary algorithms, it is possible for engineers to see all vibroacoustic quantities, including the acoustic pressure, the acoustic intensity, the operational deflection shapes of a vibrating structure at any frequency, visualize the excitation forces acting behind and inside solid enclosures, establish the interrelationship between sound radiation and structural vibration, and mitigate noise and vibration issues in the most cost-effective manner. Using these innovative technologies, engineers will be able to conduct the targeted noise control to reduce noise emission without adding masses to complex machines, thus lowering the fuel consumption and overall costs.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.
