HEARING PROTECTOR ALLOWING ACOUSTIC COMMUNICATION

描述：（改编自研究者摘要）建议开展工作， 开发一种先进的听力保护器，允许声学通信， 监测环境声音。这种先进的听力保护器利用 安装在设备的耳机上的麦克风阵列。通过处理 来自该麦克风阵列的信号，来自指定“外观”的期望信号， 相对于来自其他方向的信号，可以增强来自其他方向的信号。的 由阵列提供的定向滤波将允许面对面的声学 在许多高噪声环境中的通信，并允许用户更大的 与声学环境的接触程度比现有的 听力保护装置。第一阶段的工作将制定和评价一项 基于可穿戴数字信号处理器的功能和便携式原型。 第二阶段的工作将开发头戴式装置， 试验. 拟议的商业应用：器械的商业应用， 研究将作为一种先进的听力保护器。这种听力保护器可以让工人 在嘈杂的环境中，更好地意识到，并在他们的听觉交流， 保护环境，同时保护环境免受有害声音的影响。

DESCRIPTION: (Adapted from the Investigator's Abstract) Work is proposed to develop an advanced hearing protector that allows acoustic communication and monitoring of environmental sounds. This advanced hearing protector makes use of an array of microphones mounted on the headset of the device. By processing the signals from this microphone array, desired signals from a specified "look" direction can be enhanced relative to signals from other directions. The directional filtering provided by the array will allow face-to-face acoustic communication in many high-noise environments, and allow the user a greater degree of contact with the acoustic environment than is available with current hearing protection devices. Work in Phase I will develop and evaluate a functional and portable prototype based on a wearable digital signal processor. Work in Phase II will develop head-worn units that will be assessed in field tests. PROPOSED COMMERCIAL APPLICATION: The commercial application of the device under study will be as an advanced hearing protector. This hearing protector will allow workers in noisy environments a better sense of awareness of, and communication in, their auditory environment while still receiving protection from harmful sounds.
