Vibroacoustic Therapy & Low-Frequency Sound (LFS)

Topic: Physically perceptible low-frequency vibrations combined with music/sound → effects on stress, heart-rate variability (HRV), and subjective relaxation.

• A recent peer-reviewed article (2024) reviews the effects of vibroacoustic stimulation on psychological, physiological, and neurophysiological stress markers. This work measured ECG and EEG biosignals and reported increases in parasympathetic activity (HRV), reduced arousal, and enhanced relaxation following a Vibroacoustic Sound Massage intervention.

• A randomized controlled trial (RCT) investigated the effects of low-frequency sound vibration (LFS) combined with music on acute stress in university students.
  Findings: The experimental group showed significant improvements in HRV parameters — including LF/HF ratio and pNN50 — compared with controls, indicating enhanced autonomic nervous system regulation.

• Another study describes vibroacoustic therapy with a focus on heart-rate variability and subjective perception, using a randomized cross-over design with multiple low-frequency sound conditions.
