摘要
在实验室条件下对不同注意状态的对象进行了听阈和噪声掩蔽纯音阈值的测试,并且设计实施了目标声听辨的训练实验,训练项目包括纯音听辨、无意义语音听辨和常见目标声听辨。结果显示,人耳的听力水平与注意的集中程度显著相关,习得经验对目标声听辨能力有积极的影响,且表现出一定的规律。
The hearing threshold and the threshold of tones masked by narrow -band noise are measured for several groups of subjects with different attention. Training experiment for identifying objects is carried out, including pure tone identification, speech sound recognition and daily sound event identification. The result shows that the attention can change the test result of hearing and masking threshold. The training can improve the sound identification in noise.
