噪声中纯音听辨能力的训练效应

The effects of training on the ability of discriminating the pure-tone masked by noise

设计了一组噪声掩蔽下的纯音听辨训练实验,探究听感训练对听音人员在噪声背景下的目标信号辨别能力的影响。实验结果表明,听音训练有助于目标信号辨识能力的提高,并从统计上分析了此组听音人的目标声识别能力随训练时间的变化曲线。探讨了不同信噪比下听音者的听辨学习变化规律,以及不同个体在训练前后的听辨能力差异。

A listening training experiment to identify pure-tone masked by noise was carried out to research the influence of listening training on the auditory target identification. The result shows that the training can improve the pure-tone discriminability of listeners. The curve of target signal identifying as a function of cumulative learning time was plotted. The diversity and variation trend of tone identification between different SNR and individuals was analyzed.
