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。This paper focuses on whether masking signal with natural sounds is an effective way for mitigating annoyance caused by monotone-like tinnitus. Four natural sounds, pink noise, and narrow bandwidth noise were applied as maskers in the present study shown in this paper. Two monotones were applied as maskees. As a basis for research, natural sounds do not necessarily mask monotones entirely. According to the results, spring water and rain noise can be selected as effective noise for masking monotones. In the case of monotones with different frequency, the same masker performed a little differently on masking. We preliminarily demonstrated the feasibility of natural sounds for masking monotone-like tinnitus, which is of great use for improving maskers in tinnitus masking therapy.
