【摘要】：本文主要研究以自然声作为掩蔽信号能否缓解类似单频信号的耳鸣声带来的烦扰。文中将四种自然声、粉红噪声以及窄带噪声作为掩蔽信号,单频信号模拟类单频耳鸣声作为被掩蔽信号,比较以上提及的多种掩蔽信号的掩蔽效果。作为研究的基础,自然声并不一定要完全掩蔽单频信号,而是要减轻烦扰度。试验结果显示,水流声和雨声对于单频信号都是较为有效的掩蔽信号。对于不同频率的单频信号,同一种掩蔽信号在掩蔽效果上略有差异。该研究结果初步证实了利用自然声进行类单频耳鸣掩蔽的可行性,对改进耳鸣掩蔽治疗中的掩蔽信号具有参考意义。
[Abstract]:This paper mainly studies whether natural sound as masking signal can alleviate the annoyance caused by tinnitus sound similar to single frequency signal. In this paper, four kinds of natural sound, pink noise and narrow band noise are used as masking signals. Single frequency signal analog single frequency tinnitus is used as masking signal, and the masking effect of various masking signals mentioned above is compared. As the basis of research, natural sound does not have to completely mask single frequency signal. The experimental results show that the sound of water flow and the sound of rain are more effective masking signals for single frequency signals. There are some differences in masking effect between the same masking signal. The results of this study preliminarily confirm the feasibility of using natural sound to masking like tinnitus, which is of reference significance for improving masking signal in tinnitus masking therapy.
