摘要

腦電波在「醫學」、「心理學」以及「腦機介面」有著許多方面的應用。早期在實驗室中是透過有線的方式，將腦電波記錄下來，但隨著行動時代的來臨，無線傳輸的方式，將更有利於即時應用的開發。
本研究將在聽取不同音訊時，腦波擷取器(稱為TD1A)擷取到的類比腦波原始訊號數位化之後透過無線RF的方式傳輸至電腦中，在電腦中我們使用在LabVIEW軟體開發環境中所開發的應用程式將接收到的時域資料轉換成頻域的頻譜，並同時將時域波形與頻域的頻譜顯示出來，驗證不同的音訊對精神放鬆的效果，實驗證明白噪音的確有放鬆心情的效果。

There are many applications of brain wave, such as medicine, psychology, brain machine interface. In the early time, people used wired methods to recorde brain wave in the laboratory.In the mobile era, the wireless transmisson will be more convenient for real-time applications.
This research collected the analog brain wave signal while the experimenters were listening to different audio signals, and then converted the analog brain wave to digital form and transferred them to the computer wirelessly (The equipment we used is called TD1A).In the computer, we used a program which was developed by LabVIEW to transform the time domain data into frequency domain spectrum, and showed the time domain waveform and frequency domain spectrum at the same time. The experiments showed that the white noise indeed has the mental relaxing effects.
