- 摘要:
- 为提高助听器系统的综合性能，分析了影响滤波器组的系统延时与频率分辨率的相关参数，提出以加权叠加结构为理论基础，采用符合人耳听力特性的非等带宽通道划分方法，实现系统延时与频率分辨率的灵活配置,从而动态化调整滤波器组中的相关参数，提高助听器系统的综合性能。基于该参数设计思路设置滤波器组，选取不同类型的窗函数来验证抑制声音信号分析时频谱泄漏的影响，实验结果表明该参数设计思路是可行和有效的。
- Abstract:
- In order to improve the comprehensive performance of hearing aid system,based on the theoretical of the weighted superposition structure,a non-equal bandwidth channel division method that meets the characteristics of human hearing is adopted to realize the flexible configuration of system delay and frequency resolution,so as to dynamically adjust the relevant parameters in the filter bank，and improve the comprehensive performance of hearing aid system.Based on this kind of parameter design,filter banks are set up,and different types of window functions are selected to verify the suppression of the influence of spectrum leakage in sound signal analysis.The experiment proves that the parameter design idea is feasibility and effectiveness.
