DESCRIPTION: The development of an emergency vehicle alert system for hearing impaired drivers is proposed. This system will display a visual warning signal for hearing impaired or deaf drivers if an emergency vehicle is approaching the driver. Through the display the driver can quickly determine the distance and direction of the approaching emergency vehicle. The Phase I objective was achieved by verifying the feasibility of the proposed acoustic alert system concept. In Phase II, prototypes will be built and field tests will be conducted to determine the practical variability of the alert system. This system will consist of microphones, signal processor, and display. Several products for the same purpose are currently or were previously marketed. These devices use banks of filters and level detection and they provide only a simple warning sign. False detection rates of these devices is very high and the performance of these devices is far from satisfactory. The key goal addressed by this project is to drastically increase the accuracy and reliability of such systems while maintaining low cost. Recent strides in signal processing in the performance of low cost microprocessors makes this goal practical. PROPOSED COMMERCIAL APPLICATION: NOT AVAILABLE

描述：紧急车辆警报系统的开发， 听力受损的司机建议。 这个系统会显示一个 在紧急情况下为听力受损或失聪的驾驶员提供的警告信号 汽车正在接近司机。 通过显示器，驾驶员可以 迅速确定接近的距离和方向 紧急车辆第一阶段的目标是通过核查 建议的音响警报系统概念的可行性。 在第二阶段， 将建造原型并进行实地测试，以确定 警报系统的实际可变性。 该系统将包括 麦克风信号处理器和显示器 几种产品， 目前或以前销售的相同用途。 这些设备 使用滤波器和电平检测的银行，他们只提供一个简单的 警告信号 这些设备的错误检测率非常高， 这些装置的性能远不能令人满意。 这一关键目标 该项目的目的是大幅提高准确性， 这种系统的可靠性，同时保持低成本。 最近的进展 在低成本微处理器的性能中的信号处理 使这一目标切实可行。 拟议商业应用：不可用
