摘　　要：数字助听器是目前广大聋人康复的唯一有效手段,因此数字助听算法的研究日益重要。为便于进行助听算法的开发测试,本论文设计实现了一款基于可编程DSP的全数字助听算法开发平台pDHA。该平台具有计算功能强大、实时便携、扩展能力丰富等特点。本论文还针对此类平台的独特应用需求和相关标准,制定了一套完整的测试流程。参数测试结果表明,该系统具备足够的能力进行高级数字助听算法的开发和测试。Algorithm developing platform is very useful to the digital hearing aid, which is the only means for deaf mutes to get well. The paper introduced the construction of a DSP-based digital hearing aid algorithm developing platform, pDHA, which was powerful in computation, portable, and easy to expansion, it used TMS320VC5502 DSP as its core and supplied by a Li battery. A set of evaluation programs was designed to demonstrate its efficiency and reliability. Experimental result shows the algorithm platform is able to develop and evaluate the digital hearing and algorithm.
