摘要
该文提出了一种用于数字助听器的非等宽多通道响度补偿算法.该方法基于人耳对频率的敏感度和对声强的感知,实现了一种非等宽多通道响度补偿方案.首先将语音信号按不同的比例移动到目标频段,然后将其分成不等宽的频带,在每个频带内进行响度补偿和增益控制.实验结果表明,该方法能有效提高患者听力和助听器语音识别能力,具有较高的实用价值.
This paper proposes a non-equal-width multi-channel loudness compensation algorithm for digital hearing aids.This method implements a non-equal-width multi-channel loudness compensation scheme based on the human ear’s sensitivity to frequency and perception of sound intensity.First,move the voice signal to the target frequency band in different proportions,and then divide it into frequency bands of unequal width,and perform loudness compensation and gain control in each frequency band.Experimental results show that this method can effectively improve listening and speech recognition,and has high practical value.
