The broader impact/commercial potential of this project will be to reduce the risk of health impairments and disabilities for infants caused by high noise levels. The proposed WCIANR system can dramatically reduce the educational and public health cost by reducing hearing impairment, cognitive disorders, learning disabilities, and acute vital sign variability of NICU infants. For example, the lifetime educational cost and the lifetime cost of hearing loss have been estimated at $115,600 to $175,000 per child. The average total cost is around $2.1 billion per year. In addition, parental bonding is critical in a child's life because this first relationship determines the biological and emotional ?template? for all future relationships. The proposed WCIANR system can provide these vital bonding opportunities for NICU infants and their parents and improve infants? language development. Communicating with NICU babies can also benefit the new mothers in preventing postpartum depression and improving bonding. In addition to infant incubators, the proposed ANR system is applicable to any commercial industry where hearing protection is necessity to prevent people from hearing injury and loss, such as automotive industry, mechanical fabricating industry, medical equipment industry, mine industry and aviation industry.This Small Business Technology Transfer Research (STTR) Phase I project seeks to demonstrate the feasibility of a wireless communication integrated active noise reduction (WCIANR) system for the neonatal intensive care unit (NICU) environment, combining an improved active noise reduction (ANR) capability with a wireless unattenuated voice pass through function to permit communication with an infant. Traditional ANR systems cannot be applied directly to incubators without modification due to complicated noise models in the NICU. The NICU environment has multiple unexpected noise sources both inside and outside the incubators. The proposed system would combine feed-forward and feedback ANR systems to generate a larger zone of silence, offer deeper noise attenuation, and operate in complex noise environments. The proposed ANR system should reduce the level of the noise at the infant?s head by 20-25dB. In addition to reducing the unwanted noise reaching the infant, the WCIANR system will facilitate the two-way wireless communication between the infant and his or her parents and caregivers.

该项目更广泛的影响/商业潜力将是减少高噪音水平造成的婴儿健康损害和残疾的风险。拟议的WCIANR系统可以通过减少NICU婴儿的听力障碍、认知障碍、学习障碍和急性生命体征变异性来显著降低教育和公共卫生成本。例如，一生的教育成本和听力损失的一生成本估计为每个儿童115，600至175，000美元。平均总成本约为每年21亿美元。此外，父母的结合是至关重要的，在一个孩子的生活，因为这第一个关系决定了生物和情感？模板？所有未来的关系。拟议的WCIANR系统可以为NICU婴儿及其父母提供这些重要的联系机会，并改善婴儿？语言发展与新生儿重症监护室的婴儿沟通也可以使新妈妈们在预防产后抑郁和改善亲密关系方面受益。除了婴儿保育箱之外，所提出的ANR系统还适用于需要听力保护以防止人们听力损伤和损失的任何商业行业，例如汽车行业、机械制造行业、医疗设备行业、采矿业和航空业。这个小企业技术转移研究（STTR）第一阶段项目旨在证明无线通信集成主动降噪（WCIANR）系统在新生儿重症监护室（NICU）环境中的可行性，将改进的主动降噪（ANR）功能与无线无衰减语音传递功能相结合，以允许与婴儿进行通信。由于NICU中的噪声模型复杂，传统的ANR系统不能直接应用于孵育器而无需修改。NICU环境在培养箱内部和外部都有多个意外的噪声源。所提出的系统将结合联合收割机前馈和反馈ANR系统，以产生更大的静音区，提供更深的噪声衰减，并在复杂的噪声环境中工作。拟议的ANR系统应降低婴儿的噪音水平？s头降低20- 25 dB。除了减少到达婴儿的不必要的噪音外，WCIANR系统还将促进婴儿与其父母和护理人员之间的双向无线通信。
