現代人不論在工作上或課業上都面臨許多壓力,找尋紓壓的方式儼然成為重要課題。本論文中使用腦電圖(Electroencephalography)方式進行量測,藉由音樂給予人體刺激並觀察腦波變化。音樂方面選用海浪音訊、鋼琴音訊,以及擷取海浪音訊的低頻成分與鋼琴音訊的合成音訊,音訊格式皆為無壓縮的WAV 檔。在每項活動之前先量測基礎訊號,之後在音樂刺激過程中量測並擷取腦波訊號。 藉由音樂對於大腦影響的分析,本論文歸納出海浪音訊有最高α波能量,其次為合成音訊,最低的是鋼琴音訊。將海浪音訊低頻部分嵌入至鋼琴音訊中,確實可以提升人類大腦α波能量的喚起,並舒緩人體緊張、焦慮情緒。
The modern people had to face with many pressures. It was an important issue to find a way to alleviate pressures. In this thesis, we measure the EEG (Electroencephalography) to analysis the brain relaxation factor. The brain was affected by listening music. Thus, by music stimulating, we observed and analyzed the EEG signal variations. The kinds of music including the nature of the sea audio, piano audio and synthetic audio (the piano audio synthesis low-frequency component of sea audio). After performing the sea audio test, the α wave energy appeared highest, the next was synthetic audio test. This thesis conclude that, the low-frequency components of sea audio embedded to piano audio, will indeed improve human brain α wave energy. Thus, using the audio synthesized technology will achieve the way to alleviate pressures and anxiety.
