DEVELOPMENT OF HEADSET HEARING AIDS

描述：（根据申请人摘要改编）本项目旨在 开发先进的助听器，其中尺寸不是主要限制。 基本的模拟和数字单位计划，采用双耳耳机 带有放大电路和电池的WalkmanTM型 头带 在基本版本中，将集中精力于方向性 减少干扰噪声;元件定位以最小化反馈; 以及电源和放大器设计以保持最低失真。 的 一个数字单元，设想为一个模块添加到基本单元，将利用 新的数字信号处理芯片和压缩算法， 限制、干扰抑制和反馈减少。 形象设计 将受到特别关注。

DESCRIPTION: (ADAPTED FROM THE APPLICANT'S ABSTRACT) This is a project to develop advanced hearing aids in which size is not a primary constraint. Basic analog and digital units are planned, employing binaural headphones of the Walkman (TM) type with circuitry and batteries in an enlarged headband. In the basic version, effort will be concentrated on directivity to reduce interfering noise; component positioning to minimize feedback; and power supply and amplifier design to maintain lowest distortion. The digital unit, envisioned as a module added to the basic unit, would exploit new digital signal processing chips and algorithms for compression, limiting, interference rejection and feedback reduction. Appearance design will receive special attention.
