What the abstract reports

Preliminary analyses from a 3 × 2 × 2 crossover evaluation of 45 adults. We report only what the locked SLEEP abstract states.

This is a meeting abstract, not a full peer-reviewed paper. We do not mix in leftover marketing figures that are not in the abstract.

Protocol A

Baseline → Placebo → Sonopeace

No significant objective-sleep changes from baseline to placebo. That is the control comparison.

  • %Light, %REM, and WASO improved from placebo to Sonopeace (P’s < .01)
  • Daytime sleepiness, insomnia symptoms, and general sleep disturbance improved only after Sonopeace

Objective and subjective gains in this sequence appeared after the switch to Sonopeace, not after placebo alone.

Protocol B

Baseline → Sonopeace → Placebo

Sonopeace came first. Some improvements then held when people later used the placebo sound.

  • Significant improvements in %Deep and WASO from baseline to Sonopeace
  • Additional improvements in %SE and %REM from Sonopeace to placebo
  • Subjective measures except daytime sleepiness improved after Sonopeace and were sustained during subsequent placebo

The abstract describes objective-sleep improvements as sustained to a lesser degree than perceived benefits.

Design

How the evaluation was run

  • Participants (N = 45) randomly assigned to Sonopeace and a placebo sound condition
  • 3 × 2 × 2 crossover
  • Daily sleep data from questionnaires and the SleepScore Max device
  • Validated sleep questionnaires at the end of each study period
  • Initial analyses used ANOVA and paired t-tests

How to read this

Meeting abstract, not a paper

Accurate language: clinically studied, SLEEP 2026 abstract. Not “clinically proven.” Not “peer-reviewed paper.”

The authors describe Sonopeace as a promising, commercially available solution for improved sleep health. Individual results vary.

Study Details

Primary Study

Initial Evaluation of a Vibroacoustic Intervention for Sleep Improvement

Okun M, Dennis L, McNair P SLEEP 2026 Abstract 1283

A meeting abstract of a 3 × 2 × 2 crossover evaluation of the Sonopeace vibroacoustic sleep intervention in 45 adults with sleep difficulties. Preliminary analyses — not a full peer-reviewed paper.

Study Design

  • Participants (N = 45) randomly assigned to Sonopeace and a placebo sound condition
  • Protocol A: Baseline → Placebo → Sonopeace
  • Protocol B: Baseline → Sonopeace → Placebo
  • Daily sleep data from questionnaires and the SleepScore Max device
  • Validated sleep questionnaires at the end of each study period
  • Initial analyses: ANOVA and paired t-tests

Key Findings

  • Protocol A: no significant objective-sleep changes from baseline to placebo; %Light, %REM, and WASO improved from placebo to Sonopeace (P’s < .01)
  • Protocol A: daytime sleepiness, insomnia symptoms, and general sleep disturbance improved only after Sonopeace
  • Protocol B: significant improvements in %Deep and WASO from baseline to Sonopeace; additional %SE and %REM from Sonopeace to placebo
  • Protocol B: subjective measures except daytime sleepiness improved after Sonopeace and were sustained during subsequent placebo

The locked public evidence for Sonopeace is this meeting abstract. Preliminary analyses indicate that listening to Sonopeace is associated with measurable improvements in both objective and subjective indicators of sleep quality.

How we cite it

  • Clinically studied / SLEEP 2026 abstract — accurate
  • Not “clinically proven” and not “a peer-reviewed paper” on the strength of this cite alone
  • N = 45, as published — not a completer count from later drafts
  • Results stated by protocol, as the abstract does

Earlier research

Earlier independent work built the foundation for the SLEEP 2026 abstract.

2012

Sound Pattern Investigation (Cymatics)

Scientists resonated water with a specific frequency and discovered it produced patterns matching the sonic signatures of the human heart and brain, the first evidence that structured sound could interact with biological rhythms.

2015

Field Experiment, Davis, California

In an open-format field test, participants reported reduced stress, increased focus, and a profound sense of relaxation after listening to Sonopeace frequencies, igniting the formal scientific investigation.

Meditation Study, 22 Participants

A multi-year study demonstrated heightened clarity, deeper relaxation, and improved focus among participants. The results led directly to a biofeedback collaboration with Dr. Andres Muñoz in Spain.

Neuro/Cardio Biofeedback Study

Dr. Andres Muñoz in Marbella, Spain used EEG, HRV, electrodermal activity, and diaphragmatic breathing measurements. Found increased Alpha/Theta ratio, suggesting improved emotional regulation and stress reduction.

Neuropsychological Study with Biodevices

Francisco Marques Teixeira expected to find Theta wave activity but discovered that most participants entered a Delta state, the brainwave pattern associated with deep sleep. Biofeedback devices independently confirmed the finding.
