DEVELOPMENT OF HEADSET HEARING AIDS

描述：(改编自申请人的摘要)这是一个项目，旨在 开发尺寸不是主要限制的先进助听器。 规划了基本的模拟和数字单元，采用双耳耳机 带有电路和电池的随身听(TM)型 头带。在基本版本中，工作将集中在指向性上 减少干扰噪声；元件定位，最大限度地减少反馈； 以及电源和放大器设计，以保持最低的失真。这个 数字单元，被设想为添加到基本单元的模块，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。外观设计 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.
