This dissertation is different from traditional speech enhancement methods which are based on noise characteristic such as adaptive noise cancellation or spectral subtraction processing. in this dissertation the speech signal conducted by bone was taken as the object to be studied and the exploitive study on the acoustical characteristic of speech signal conducted by bone was performed by the method of theory combined with experiment. then a proposition about speech reconstruction based on speech signal conducted by bone was presented, and the design of software and hardware was completed
本文與傳統的基於噪聲特性的自適應噪聲抵消法、頻譜減法等語音增強降噪技術不同,是以骨導語言為研究對象,採用理論與實驗相結合的方法對骨導信號的聲學特性進行了探索性研究,進而提出了基於骨導信號的語音重構技術,並完成了相應的軟硬體開發。The refinements made to the original methodology are based upon not only the abroad new research about noise evaluation, but also upon the thought of the domestic base of current noise evaluation. the procedure involves not only considering the noise sound pressure level, but also considering the speech interference level and noise spectrum balance problems, which offer enough information about building noise environment for engineer and owner
該評價方法借鑒了國外在噪聲評價方面最新的研究成果,同時也考慮了國內目前的噪聲評價狀況,該方法不僅僅考慮了噪聲聲壓級一個因素,同時還考慮了語言干擾級,以及噪聲頻譜的平衡性等問題,給工程人員以及建築業主提供了建築聲環境方面充足的信息,這是很有意義的。According to fourier transform principle, a program is designed with c and assemble words to analyze the high frequency ultrasonic signals in frequency domain in this paper
論文根據離散傅立葉變換及逆變換原理,用c語言和匯編語言編程設計了高頻超聲信號的頻譜分析軟體。
