dc.description.abstract心率變異性源自心臟搏動速率隨時間不斷的在變化。這種不斷變異的現象主要受人體自主神經系統所控制。在過去二十幾年的研究當中,心率變異性分析已成為越來越普遍的自主神經系統功能性指標。而日常生活中舉凡各種內臟功能、血壓、情緒變化乃至生活壓力等等…,都和自主神經系統的調節息息相關。因此本研究以心率變異性為生理觀測指標,觀察不同節奏特性之音樂所造成的自主神經系統調變情形。 本研究基於音樂感知、音訊處理和心電訊號分析提出音樂的兩大節奏特性(節拍速度和節奏複雜度)調變心率變異性之假設。並由實驗結果發現,擁有節拍速度較快且複雜度較低之特性的節奏樣本,有較明顯的同步能力。所謂同步能力即音樂節奏促使心跳節奏產生改變並趨於相似之特性。此外在聆聽完此種特性之節奏樣本後,交感神經系統與副交感神經系統活性之比值的下降情形最為顯著,達到一種甚至比平常休息時更為放鬆的生理狀態。在硬體實做方面,本研究在精確度損失極少的前提下,針對所採用之QRS 波偵測演算法進行部分簡化以減少硬體設計之複雜度,並透過心電圖標準資料庫的驗證,實現高準確率且低成本的QRS 波偵測晶片。 透過系統化的研究方法,了解各種不同特性的音樂對人體自主神經系統造成的影響,以期藉由音樂調節身心,讓生活更加健康。zh_TW
dc.description.abstractHeart rate variability (HRV) is a measure of variations in the heat rate. Over the last 25 years, HRV analysis has became more and more popular as a non-invasive research and clinical tool for indirectly investigating both cardiac and autonomic nervous system (ANS) function in both health and disease area. It is choused as the physiological indicator for observing musical effect on ANS modulation. In this study, the concept of two musical rhythmic features, tempo and complexity, modulating human ANS is proposed. The main findings in this work are as follows. The rhythm pattern with faster tempo and lower complexity is observed to decrease the LF/HF and SDNN measure significantly in the resting period after the loop listening rather than the stable resting state. In the hardware implementation part, a high accuracy and low cost QRS detector SoC is realized. By understanding the relationship between music and the function of ANS, we can improve our life and health by music – non-invasively and simply.en_US
