Abstract

Background: Although it is known that sound exposure evokes changes in autonomic activity, the effects of noise and music on the nonlinear behavior of heart rate fluctuations remain poorly understood and controversial. This study aims to assess the influence of sound subjective emotional valence and arousal on the nonlinear characteristics of the autonomic nervous system during passive listening.

Methods: In this study, 42 subjects listened to four sounds: (1) white noise, (2) road traffic noise, (3) excitatory music, and (4) a lullaby. The experiment consisted of two consecutive sessions: 5 minutes of rest, followed by 5 minutes of listening. RR intervals were recorded during both sessions. The following linear and nonlinear heart rate variability (HRV) indices were computed: Standard deviation of NN (SDNN), The root mean square of successive differences between normal heartbeats (RMSSD), F, high frequency (HF), approximate entropy (ApEn) and sample entropy (SampEn), correlation dimension (D2), Poincaré plot indices (SD1, SD2), fractal scaling exponents (alpha1, alpha2), and recurrence plot indices (mean line length [Lmean], maximum line length [Lmax], determinism [DET], laminarity [LAM], maximal vertical length [Vmax], trapping time [TT], Shannon entropy of line length distribution [ShanEn]).

Results: Excitatory music was associated with a significant decrease in SDNN (from 47.3 ± 3.59 to 38.31 ± 3.16, P < 0.01), RMSSD (from 51.07 ± 4.75 to 42.53 ± 3.9, P < 0.05), HF (from 1516.26 ± 245.74 to 884.07 ± 183.44, P < 0.001), and low frequency (LF; from 973.33 ± 176.09 to 760.28 ± 150.35, P < 0.05). Excitatory music exposure induced significant increases in DET (P < 0.01), SD1 (P < 0.05), and SD2 (P < 0.05), but changes in detrended fluctuation analysis (DFA), SampEn, and D2 were nonsignificant. Traffic noise, white noise, and the lullaby did not cause significant changes in the measures of HRV.

Conclusion: Presentation of excitatory music that evokes strong negative emotions elicits a prominent decrease in respiratory sinus arrhythmia. Poincaré plot and recurrence plot measures possess high sensitivity to excitatory music. Contrary to previous studies, we did not find the effects of relaxing music on HRV.

听觉刺激对心率非线性动力学的影响：情绪效价和唤醒的影响。

背景：尽管众所周知，声音暴露会引起自主神经活动的变化，但噪音和音乐对心率波动的非线性行为的影响仍然知之甚少，也存在争议。本研究旨在评估被动听力过程中声音主观情绪效价和唤醒对自主神经系统非线性特征的影响。方法：在本研究中，42名受试者听了四种声音：（1）白噪音，（2）道路交通噪音，（3）兴奋性音乐和（4）摇篮曲。实验包括两个连续的环节：休息5分钟，然后听5分钟。两次治疗期间均记录RR间期。计算了以下线性和非线性心率变异性（HRV）指数：NN的标准差（SDNN）、正常心跳之间连续差异的均方根（RMSSD）、F、高频（HF）、近似熵（ApEn）和样本熵（SampEn）、相关维数（D2）、庞加莱图指数（SD1，SD2）、分形标度指数（alpha1，alpha2），和递推图指数（平均线长[Lmean]、最大线长[Lmax]、确定性[DET]、分层性[LAM]、最大垂直长度[Vmax]、捕获时间[TT]、线长分布的Shannon熵[SanEn]） ± 3.59至38.31 ± 3.16，P<0.01），RMSSD（从51.07 ± 4.75至42.53 ± 3.9，P<0.05）、HF（从1516.26 ± 245.74至884.07 ± 183.44，P<0.001）和低频率（LF；从973.33 ± 176.09至760.28 ± 150.35，P<0.05）。兴奋性音乐暴露引起DET（P<0.01）、SD1（P<0.05）和SD2（P<0.05）显著增加，但去趋势波动分析（DFA）、SampEn和D2的变化不显著。交通噪声、白噪声和摇篮曲对HRV的测量没有显著变化。结论：呈现能唤起强烈负面情绪的兴奋性音乐能显著降低呼吸窦性心律失常。庞加莱图和递归图测度对兴奋性音乐具有较高的敏感性。与之前的研究相反，我们没有发现放松音乐对HRV的影响。

期刊介绍： Noise and Health is the only International Journal devoted to research on all aspects of noise and its effects on human health. An inter-disciplinary journal for all professions concerned with auditory and non-auditory effects of occupational, environmental, and leisure noise. It aims to provide a forum for presentation of novel research material on a broad range of topics associated with noise pollution, its control and its detrimental effects on hearing and health. It will cover issues from basic experimental science through clinical evaluation and management, technical aspects of noise reduction systems and solutions to environmental issues relating to social and public health policy.
