Implication

Acoustic stimulation may enhance acute HRV in healthy adults; hypothesis-generating and should not yet change practice.

Structured PICO

Does rotating acoustic stimulus improve heart rate variability in healthy adults?

Population

31 healthy adults (11 male; 20 female; average age 36 ±12 yrs). Exclusion criteria: any current disease condition, ongoing medication regimen, and any history of cardiac, neurological, psychiatric or sleep disorder.

Intervention

Rotating acoustic stimulus (constructed from an Indian percussion instrument tabla, played at ~50 db for 9.5 mins, modulated at 2 Hz) delivered binaurally via headphones.

Comparator

Pre-stimulation baseline (each subject served as their own control, with ECG recorded for 10 minutes before exposure).

Outcome

Heart rate variability (HRV) parameters in time and frequency domain (including heart rate, SD, RMSSD, SD1, SD2, SD12, and DFA exponent alpha) measured immediately after stimulation.surrogate

A rotating acoustic stimulus acutely increases parasympathetic activity and improves heart rate variability in healthy adults.

Limitations

Results obtained were an immediate reflection of the stimulus, without assessment of the duration of the effect on the autonomic nervous system.
