许多研究揭示了音乐，特别是它的节奏，对自主神经系统(ANS)和呼吸模式的影响。由于ANS和呼吸系统之间存在相互作用，即交感-呼吸耦合，因此音乐节奏对ANS的影响可能是由呼吸系统调节的。因此，我们研究了音乐节奏和呼吸频率之间的关系对ANS的影响。52名年龄在18-35岁的健康人参与了这项研究。他们使用无声的电子节拍器控制呼吸频率，并以恒定的节奏听简单的鼓声。我们改变了呼吸频率-声学节奏组合。呼吸频率控制在15或20次/分钟(CPM)，声速为60或80次/分钟(BPM)或环境安静。分别用心电图和弹性胸带测量心率和呼吸频率。以平均心率和心率变异性(HRV)作为ANS活动的指标。只有当呼吸频率控制在20cpm，声速控制在80bpm时，我们观察到平均心率和HRV的低(0.04-0.15 Hz)与高(0.15-0.40 Hz)频率比显著增加。我们认为声学节奏对交感神经张力的影响是由呼吸系统调节的。
Many studies have revealed the influences of music, and particularly its tempo, on the autonomic nervous system (ANS) and respiration patterns. Since there is the interaction between the ANS and the respiratory system, namely sympatho-respiratory coupling, it is possible that the effect of musical tempo on the ANS is modulated by the respiratory system. Therefore, we investigated the effects of the relationship between musical tempo and respiratory rate on the ANS. Fifty-two healthy people aged 18–35 years participated in this study. Their respiratory rates were controlled by using a silent electronic metronome and they listened to simple drum sounds with a constant tempo. We varied the respiratory rate—acoustic tempo combination. The respiratory rate was controlled at 15 or 20 cycles per minute (CPM) and the acoustic tempo was 60 or 80 beats per minute (BPM) or the environment was silent. Electrocardiograms and an elastic chest band were used to measure the heart rate and respiratory rate, respectively. The mean heart rate and heart rate variability (HRV) were regarded as indices of ANS activity. We observed a significant increase in the mean heart rate and the low (0.04–0.15 Hz) to high (0.15–0.40 Hz) frequency ratio of HRV, only when the respiratory rate was controlled at 20 CPM and the acoustic tempo was 80 BPM. We suggest that the effect of acoustic tempo on the sympathetic tone is modulated by the respiratory system.
