【摘要】：本文主要研究以自然聲作為掩蔽信號能否緩解類似單頻信號的耳鳴聲帶來的煩擾。文中將四種自然聲、粉紅噪聲以及窄帶噪聲作為掩蔽信號,單頻信號模擬類單頻耳鳴聲作為被掩蔽信號,比較以上提及的多種掩蔽信號的掩蔽效果。作為研究的基礎(chǔ),自然聲并不一定要完全掩蔽單頻信號,而是要減輕煩擾度。試驗(yàn)結(jié)果顯示,水流聲和雨聲對于單頻信號都是較為有效的掩蔽信號。對于不同頻率的單頻信號,同一種掩蔽信號在掩蔽效果上略有差異。該研究結(jié)果初步證實(shí)了利用自然聲進(jìn)行類單頻耳鳴掩蔽的可行性,對改進(jìn)耳鳴掩蔽治療中的掩蔽信號具有參考意義。
[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.
