摘要：

设计面向老年性听力损伤患者的数字式助听器,对语音信号进行响度补偿时需要同时兼顾频率与声强级。针对人耳听觉的这一特性,归纳提出了动态压缩响度补偿策略。同时分别从对患耳敏感的低频域和高频域语音两个层面深入进行Matlab仿真验证。结果表明,此研究对于保证数字式助听器中响度补偿效果的合理性以及完整性具有重要意义。

关键词: 数字式助听器, 响度补偿, 动态压缩, 语音频率

Abstract:

A digital hearing aid is designed for patients with age-related hearing damage with both frequency and sound intensity level in mind in the voice signal loudness compensation.Based on the characteristics of the human auditory,a dynamic compressed loudness compensation strategy is proposed.The ear-sensitive low-frequency and high-frequency to speeches are simulated in Matlab.The results indicate that this compensation strategy guarantees the rationality and integrity of the loudness compensation effect of the digital hearing aids.

Key words: digital hearing aids;loudness compensation;dynamically compressed;voice frequency
