聲音資訊之形體化研究

聲音為空間中主要的不可視資訊，其狀態可以由聲波的振動來理解，這股振動的力量可以生成一種動態而且有序的形。將空間中的聲音以形體表現，可與空間形體以最直接的方式呈現其關係。本研究以單體振動流體產生的Cymatics以及非牛頓流體運動分析聲音對於形體的發生以及狀態造成的影響做為基礎，分析結果編寫可重現實驗的程式。研究過程以視訊鏡頭捕捉實驗中流體的運動，再將影像資訊轉化為數位模型，與程式運算結果比較，並以實體實驗產生的數據重新調整參數，使程式運算達到逼近實體實驗的結果。產生可控制的形體程式後，編程聲音程式來獲取實際基地中的聲音資訊，並使用形體程式模擬出空間中聲音資訊所產生的形體與其狀態，以探討聲音產生的力量與形體變化對於空間的影響與可能性。

Sound is one of main invisible information in space. We could comprehend its status through vibration of sound waves. The most direct way to display the relation between sound and space is generating animate form with the power of vibration. This research is based on Cymatics, which studies patterns generated from using different hertz to vibrate water. Non-Newtonian fluid was also used to replace water and to produce forms of sound. The research consists of four parts. The first part is writing a program to recreate dynamic forms of sound from the experiment. The second part is using webcam to catch images of the experiment and analyze the data by means of computer-aided tools. The third part is to compare results from the experiment and the program and correspondingly adjust parameters for more accurate simulation. The last part of the research is about implementation. Six wireless microphones were used to get data of sound in a real space. Using the data as input parameters, the form of the sound was generated. Possibility of using sound to produce forms and its impact on space has been explored and evaluated.
