    摘要: 　　本研究主要探討年輕健康受試者在聆聽不同運算放大器調節後的音樂，對於心率變異的影響。研究對象為某大學日間部學生共20 名，包含女性10 名，其平均年齡為21.4±1.5 歲；男性10 名，其平均年齡為22.0±1.4 歲。研究設計為受試者內設計；研究模組的設計包含一組控制組及一組實驗組，設有六組研究模組(Model OP-None、Model AD8022、Model AD8012、Model NE5532、Model TL082、Model OPA2134)，研究測量使用心率變異指標：平均心跳間距(the time average of RR-intervals, RRI)；正常竇性心搏間期之標準差(standard deviation of all normal to normal intervals, SDNN)；平均心跳數(the time average of heart rate, HR)；正常心跳間期差值平方和的均方根(the square root of the mean of the sum of the squares of 心率變異的影響。研究對象為某大學日間部學生共20 名，包含女性10 名，其平均年齡為21.4±1.5 歲；男性10 名，其平均年齡為22.0±1.4 歲。研究設計為受試者內設計；研究模組的設計包含一組控制組及一組實驗組，設有六組研究模組(Model OP-None、Model AD8022、Model AD8012、Model NE5532、Model TL082、Model OPA2134)，研究測量使用心率變異指標：平均心跳間距(the time average of RR-intervals, RRI)；正常竇性心搏間期之標準差(standard deviation of all normal tonormal intervals, SDNN)；平均心跳數(the time average of heart rate, HR)；正常心跳間期差值平方和的均方根(the square root of the mean of the sum of the squares of differences between adjacent NN intervals, RMSSD)；低頻功率(low frequency power,LF)；高頻功率(high frequency power, HF)；總功率(total power, TP)。　　　當運算放大器對於原始音樂之低音、中音及高音音樂頻寬振幅分佈為平均增益或抑制時，運算放大器調節之實驗音樂對於人體心率變異之影響與未調節的原始音樂刺激效果相仿，如運算放大器AD8022、TL082 及OPA2134；當運算放大器對於原始音樂之低音(極低音部分至低音)、中音頻寬(上段中音)及高音頻寬(下段高音)的振幅產生抑制時，則會對於男性及女性的心率變異產生放鬆效果，如運算放大器AD8012；當運算放大器對於原始音樂之低音頻寬(極低音至低音)、中音頻寬(上段中音)及高音頻寬的振幅產生抑制時，則會對於男性及女性的心率變異產生刺激效果，如運算放大器NE5532。　　　而聆聽10 分鐘節奏為150BPM 的未調節或經運算放大器調節後印度民族梵語音樂，都會使得心率變異的TP 值下降，產生放鬆效果。　　　顯示藉由運算放大器調節音樂中特定頻寬來刺激人體聽覺系統後，會影響自律神經系統的平衡性；因此本研究可作為未來進一步探討調整音樂頻寬振幅刺激人體聽覺系統如何調整自律神經活動的基礎。
    　　The purpose of the present study was to investigate the effect of listening to the music with operational amplifiers(OP-Amps) on HRV activity in young healthyindividuals. This study was a within subject design and pretest-posttest experimental design trial carried out on 20 healthy undergraduate students including 10 femalesubjects, mean age 21.4 ± 1.5 years; 10 male subjects, whose average age was 22.0 ± 1.4 years. Participants were allocated to all of six study models including (1) ModelOP-None, (2) Model AD8022, (3) Model AD8012, (4) Model NE5532, (5) Model TL082, and (6) Model OPA2134. Each study model included a control group and a stimuli group. Participants in the stimuli group were asked to listen to indian cultural music in sanskrit with or without OP-Amps for 10 minutes.　　　The outcome measure involved HRV indices including the time average of RR-intervals, RRI; standard deviation of all normal to normal intervals, SDNN; the time average of heart rate, HR; the square root of the mean of the sum of the squares of differences between adjacent NN intervals, RMSSD; low frequency power, LF; high frequency power, HF; total power, TP. The values of HRV were used to quantifymodulation of the sympathetic and parasympathetic branches of the autonomic nervous system.　　　Listening to indian cultural music in sanskrit with OP-Amps included AD8022, TL082 and OPA2134 will have the same effects as the non-modulated indian cultural music in sanskrit. Listening to indian cultural music in sanskrit with AD8012 will have relax effects on HRV. Listening to indian cultural music in sanskrit with NE5532 will have stiluli effects on HRV.　　　As the results, listening to indian cultural music in sanskrit with or without OP-Amps for 10 minutes will lower the total power of HRV and let the participants relax.　　　Clearly, stimulating the human auditory system by modulating particular audio bandwidths would affect the balance of the autonomic nervous system. The findingsdescribed in this study can be served as a reference for studies of music therapy in the future.
