[Research on masking effect of multiple natural sounds for monotone-like tinnitus].

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.
