HEARING PROTECTOR ALLOWING ACOUSTIC COMMUNICATION

描述：(改编自《调查者摘要》)工作建议 开发一种先进的听力保护器，允许声音通信和 对环境声音的监测。这款先进的听力保护器 安装在设备头戴式耳机上的麦克风阵列。通过加工 来自此麦克风阵列的信号，来自指定“外观”的所需信号 相对于来自其他方向的信号，方向可以被增强。这个 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进行通信，并允许用户获得更大的 与声学环境的接触程度高于电流可用的程度 听力保护装置。第一阶段的工作将制定和评估 基于可穿戴数字信号处理器的功能齐全、便携的样机。 第二阶段的工作将开发出将在现场进行评估的头戴式设备 测试。 拟议的商业应用：设备在以下条件下的商业应用 学习将成为一种高级听力保护器。这种听力保护器将允许工作人员 在嘈杂的环境中，更好地意识到他们的听觉并在其中进行交流 在保护环境的同时，仍能免受有害声音的伤害。

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.
