STTR Phase II: Modular Feedforward Adaptive Noise Control

这一小型企业技术转移(STTR)第二阶段项目旨在开发一种廉价、多用途的有源降噪(ANR)模块和相关软件评估工具，可广泛应用于许多职业环境。该项目将开发信号处理算法，以提高ANR的计算效率。目前的第二阶段目标包括：(1)为两个市场开发能够实现单通道和多通道ANR的多功能ANR模块和相关的ANR软件模块：商用车驾驶室的“静区”ANR和噪声咨询业的有源降噪产品；(2)开发相应的软件工具套件，供噪声顾问使用有源降噪产品对噪声环境进行交钥匙改造；以及(3)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)可生产的ANR硬件模块和相关的模块化ANR软件，(2)一套用于噪声咨询行业的ANR评估工具，通过现场测试进行验证，以及(3)来自几个完整示范项目的模块化ANR概念的实验结果。对新噪声控制技术的强大吸引力是日益严格的政府和社区法规、行业标准、越来越多的关于噪声诱发听力损失(NIHL)的科学证据以及数百万美元的职业性听力残疾补偿成本的结果。目前的商业模式是建立在伙伴关系的基础上的，在这种伙伴关系中，专有的“即插即用”ANR模块代表着由其他工业组织制造和销售的产品以及由声学顾问进行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.
