This Small Business Innovation Research (SBIR) Phase I project will investigate a novel MEMS based microphone based on entirely new design principles. By abandoning the traditional 100 year-old microphone architecture common to both full-scale microphones as well as recently commercialized MEMS microphones, this project will explore a vastly superior acoustical design that will result in substantial improvements in fidelity and SNR (20 dB SNR improvement over existing MEMS microphones). Furthermore, the microphone will have an inherently directional response with the benefit of focusing on a speaker or event of interest while rejecting ambient background noise. These attributes make this innovation ideal for addressing an emerging need of high volume consumer communication device manufactures that are looking for acoustic sensing innovations with the unique combination of high performance and low manufacturing cost. If successful the proposed innovation will enable, for the first time, the introduction of performance-audio quality into a suite of consumer communication devices. The primary customer focus for this innovation is high volume consumer communication device manufacturers with applications on their horizon that demand substantial improvements in microphone component performance. Presently, commercial suppliers of MEMS microphones all use variations of a traditional microphone architecture which has proven incapable of addressing high performance applications, in particular those that require high fidelity and directionality. Additional markets and applications for this innovation include acoustic instrumentation, performance audio, military and defense, intelligence gathering, speech recognition (ex. in laptop computers), and hearing aids. Addressing hearing aid markets will have a societal impact as well, as patient satisfaction with hearing aid devices is presently very low. The innovation is also expected to have other audiological applications including use in hearing health monitoring systems based on otoacoustic principles. Clinical tools and instruments based on this innovation will serve to enhance scientific and technological understanding in many fields of acoustics.

这项小型企业创新研究（SBIR）I阶段项目将根据全新的设计原理研究一个基于MEMS的新型麦克风。通过放弃全面麦克风和最近商业化的MEMS麦克风共同的传统100年历史的麦克风结构，该项目将探索一种巨大的声学设计，从而可以大大改善保真度和SNR（20 dB SNR比现有MEMS MICROPHONES的改善）。此外，麦克风将具有固有的方向响应，其优点是专注于说话者或感兴趣的事件，同时拒绝环境背景噪声。这些属性使这项创新是满足大量消费者通信设备制造的新兴需求的理想之选，该制造方式正在寻找具有高性能和低制造成本的独特组合的声学传感创新。如果成功的话，提出的创新将首次将绩效原告质量引入一系列消费者通信设备。这项创新的主要客户重点是高批量的消费者通信设备制造商，其应用程序上的应用程序需要大大改善麦克风组件性能。目前，MEMS麦克风的商业供应商都使用传统麦克风结构的变体，该麦克风结构证明无法解决高性能应用，特别是那些需要高保真和方向性的应用程序。这项创新的其他市场和应用包括声学仪器，性能音频，军事和国防，情报收集，语音识别（Ex。在笔记本电脑中）和助听器。解决助听器市场也将产生社会影响，因为目前对助听器设备的患者满意度非常低。预计该创新还具有其他听力学应用程序，包括基于耳声原理中的听力健康监测系统。基于这项创新的临床工具和工具将在许多声学领域增强科学和技术理解。
