SBIR Phase II: A Robust and Cost-Effective Tool for Diagnosing Manufacturing Noise Problems

这项小型企业创新研究（SBIR）第二阶段项目将开发并商业化下一代质量控制工具，以评估生产线上任何发声产品的质量。这项新技术最显著的科学优点是它能够抑制背景噪声的干扰，并在嘈杂的环境中提取任何目标源的真实声学特性。目前的测量设备测量的是整体信号，包括目标源的信号和背景噪声。本研究预计将对减少噪音污染和提高制造环境中的劳动力能力产生广泛影响。这项技术将帮助美国制造商通过减少噪音排放，降低与噪音相关问题相关的保修成本，并帮助确保遵守越来越多的地方和联邦政府关于噪音污染的法规和法律，从而在全球范围内竞争。

This Small Business Innovation Research (SBIR) Phase II project will develop and commercialize a next generation quality control tool to assess the quality of any sound-generating product on a production line. The most significant scientific merit of this new technology is its capability to suppress the interference of background noise and extract the real acoustic characteristics of any target source in a noisy environment. Current measurement devices measure the overall signal, which includes the signal of a target source and background noise. This research is expected to have broad impact on reducing noise pollution and improving workforce capabilities in a manufacturing environment. This technology will help the U.S. manufacturers to compete globally by reducing noise emissions, lowering warranty costs associated with noise related issues, and helping ensure compliance with a growing number of local and federal government regulations and laws on noise pollution.
