DESCRIPTION (provided by applicant): The continued research and development of a portable, inexpensive, system for ambient noise attenuation is proposed for use in audiometric testing. The device will be a technologically advanced headset used in conjunction with insert earphones. In combination, the total attenuation of the device will be superior to any current portable alternative. This combination of headset and insert earphones will be designed to attenuate ambient acoustic noise during audiometric testing, and will replace sound isolation test rooms and mobile test facilities under certain ambient noise conditions. The portability of the system will enable it to be used in venues such as schools, nursing homes, prisons, and industrial plants. The result of this research will be tested pre-production units. The ultimate goal of this research and development will be to manufacture a portable audiometric testing system that provides noise-attenuation properties superior to a single-walled room in meeting ANSI S3.1-1 999 standards.

描述（由申请人提供）：继续研究和开发一种便携式、廉价的环境噪声衰减系统，用于听力测试。该设备将是一个技术先进的耳机与插入式耳机一起使用。结合起来，该装置的总衰减将优于任何当前便携式替代品的上级。这种耳机和插入式耳机的组合将被设计为在听力测试期间衰减环境噪声，并将在某些环境噪声条件下取代隔音测试室和移动的测试设施。该系统的便携性将使其能够在学校、养老院、监狱和工厂等场所使用。这项研究的结果将测试预生产单位。这项研究和开发的最终目标将是制造一种便携式听力测试系统，该系统在满足ANSI S3.1-1 999标准方面提供比单壁房间更上级的噪声衰减特性。
