声音可以诱导听者的自主反应。然而，对音乐中特定频率成分的调制作用还没有完全了解。在这里，我们研究了音乐的频率成分对自主神经反应的作用。具体地说，我们展示了在高频或低频域被放大的音乐。12名健康的女性听白噪音，一种引起压力的噪音，然后听一段音乐的三个版本之一：原创的、低频率的或高频放大的。为了测量自主神经反应，我们用心电图从心率计算高频归一化单位(HFnu)、低频归一化单位和低频/高频比值。我们将应激恢复率定义为受试者在抓挠噪声后听音乐后获得的值，按受试者在应激噪声后听白噪声后获得的值归一化，以HFnU、低频归一化单位、低频/高频比和心率为指标。结果表明，高频放大音乐在三个版本中具有最高的HFnU。高频放大刺激下HFNU的应力恢复率显著大于低频刺激下。我们的结果表明，音乐的高频成分在缓解压力方面比低频成分起到更大的作用。
Sounds can induce autonomic responses in listeners. However, the modulatory effect of specific frequency components of music is not fully understood. Here, we examined the role of the frequency component of music on autonomic responses. Specifically, we presented music that had been amplified in the high- or low-frequency domains. Twelve healthy women listened to white noise, a stress-inducing noise, and then one of three versions of a piece of music: original, low-, or high-frequency amplified. To measure autonomic response, we calculated the high-frequency normalized unit (HFnu), low-frequency normalized unit, and the LF/HF ratio from the heart rate using electrocardiography. We defined the stress recovery ratio as the value obtained after participants listened to music following scratching noise, normalized by the value obtained after participants listened to white noise after the stress noise, in terms of the HFnu, low-frequency normalized unit, LF/HF ratio, and heart rate. Results indicated that high-frequency amplified music had the highest HFnu of the three versions. The stress recovery ratio of HFnu under the high-frequency amplified stimulus was significantly larger than that under the low-frequency stimulus. Our results suggest that the high-frequency component of music plays a greater role in stress relief than low-frequency components.
