single frequency sound 中文意思是什麼
single frequency sound
解釋
單頻聲-
Spread on a metal plate. he meticulously catalogued the symmetrical, geometrically perfect structures and elegant sound mandalas that resulted from directing hundreds of different frequency and rhythmic combinations, from single tones and intervals to complex musical harmonies, through the plate.
他稱這個新的研究領域為cymatics ，並且將不同頻率，節奏的單音，間歇音，復雜合聲做了幾百種不同的組合，對物質粉末由於這些振動而形成的完美，對稱的結構和精美的曼陀羅高度復雜的對稱幾何圖案進行了精確的分類。 -
Through research on principle and approach, this paper puts forward three new methods in power cable fault location. the first method is based on wavelet reconstruction, and the measured signal which is the difference between the faulty and sound phase current under the high voltage pulse excitation, is transformed using wavelet, and the high frequency component is reconstructed at single scale
基於小波重構的電纜故障測距方法採用脈沖電源作用下故障相與健全相的電流差作為測量信號，利用小波變換對其作多尺度分解，然後對信號在高頻下進行單支重構。 -
At the beginning of this thesis, we introduce the fundamental of the acoustics and the perceptual mechanism. next, different kinds of speech processing methods including time processing and time - frequency analysis are presented, such as short time average energy, short time cross zero analyses, short time autocorrelation function analyses and fft. at last, we focus on the sound separation, especially on single channel sound separation
在這篇文章開始的部分，我們介紹了聲學的基礎知識和人類聲音感知的機理;接下來，我們給出了在時域處理和頻域處理語音信號的一些經典的技術，比如短時平均能量分析、短時過零分析、短時自相關函數分析、快速傅立葉變換等;本文重點從理論和實驗上討論語音分離，特別是單聲道語音分離的演算法及其在分離音樂鼓點中應用。 -
