Key result
Excitatory music linked to ~19% lower SDNN, indicating decreased parasympathetic activity.
Why the study?
The effects of noise and music on the nonlinear behavior of heart rate fluctuations remain poorly understood and controversial.
Does auditory stimulation with different sounds alter linear and nonlinear heart rate variability indices in human subjects?
Population
42 subjects
Comparison
Four sounds (white noise, road traffic noise, excitatory music, lullaby) vs 5 minutes of rest

Does auditory stimulation with different sounds alter linear and nonlinear heart rate variability indices in human subjects?
Absolute Event Rate: 38.31% vs 47.3%
p-value: p=<0.01
Excitatory music significantly alters autonomic nervous system activity as measured by linear and nonlinear heart rate variability indices, whereas white noise, traffic noise, and lullabies do not.
Dimitriev et al. (2023) conducted a cross-sectional in Healthy subjects (n=42). Auditory stimulation (excitatory music) vs. Rest (baseline) was evaluated on Standard deviation of NN intervals (SDNN) (p=<0.01). Excitatory music significantly decreased heart rate variability, including a reduction in SDNN from 47.3 to 38.31 ms, indicating a prominent decrease in parasympathetic activity.
