STTR Phase II: Modular Feedforward Adaptive Noise Control

该小型企业技术转让（STTR）第二阶段项目旨在开发一种廉价的多用途主动降噪（ANR）模块和相关的软件评估工具，可广泛应用于许多职业环境。 该项目将开发提高ANR计算效率的信号处理算法。 目前的第二阶段目标包括：（1）开发一个多用途的ANR模块和相关的ANR软件模块，能够为两个市场提供单通道和多通道ANR：商用车辆驾驶室中的“安静区”ANR和噪声咨询行业的主动降噪产品;（2）开发一套相应的软件工具，供噪音顾问公司使用，以便为噪音环境提供主动噪音消减产品，在商业化合作伙伴的支持下，在示范项目中对ANR模块、软件和工具套件进行全面的现场评估。第二阶段的预期技术成果包括：（1）一个具有相关模块化ANR软件的可编程ANR硬件模块，（2）一套用于噪声咨询行业的ANR评估工具，通过现场测试和（3）从几个完整的模块化ANR概念的实验结果进行验证，大规模的示范项目。新的噪音控制技术的强大吸引力是越来越严格的政府和社区法规，行业标准，越来越多的科学证据表明噪声性听力损失（NIHL），以及数百万美元的职业性听力残疾赔偿费用。 目前的商业模式是基于合作伙伴关系，其中专有的“即插即用”ANR模块代表了其他工业组织制造和销售的产品以及声学顾问安装的品牌嵌入式组件。

This Small Business Technology Transfer (STTR) Phase II project seeks to develop an inexpensive, multi-purpose active noise reduction (ANR) module and associated software evaluation tools with broad commercial application to many occupational environments. This project will develop signal processing algorithms that improve the computational efficiency for ANR. The current Phase II objectives include: (1) developing a multi-purpose ANR module and associated ANR software modules capable of single- and multi-channel ANR for two markets: "quiet zone" ANR in commercial vehicle cabins and active noise abatement products for the noise consulting industry; (2) developing a corresponding suite of software tools to be used by noise consultants for turnkey retrofits of noisy environments with active noise abatement products, and (3) conducting full-scale in-situ evaluation of the ANR module, software, and tool suite in demonstration projects with the support of commercialization partners. The expected technical outcomes of Phase II include: (1) a manufacture-ready ANR hardware module with associated modular ANR software, (2) a suite of ANR evaluation tools for the noise consulting industry, validated through in-situ testing and (3) experimental results of the modular ANR concept from several full-scale demonstration projects.The strong pull for new noise control technologies is the result of increasingly strict government and community regulations, industry standards, the growing body of scientific evidence of on noise-induced hearing loss (NIHL), and the multimillion dollar cost of occupational hearing disability compensation. The current business model is based on partnerships in which the proprietary 'Plug-and-Play' ANR module represents a branded embedded component for products manufactured and marketed by other industrial organizations and for installations by acoustical consultants.
