Frequency Healing Claims: An Evidence Audit

Tier A — supported contexts

• Music therapy with trained clinicians — anxiety, pain, perioperative distress.^[3]
• Environmental masking — sleep in noisy wards/homes.^[7]
• Nature sound stress recovery — laboratory autonomic markers.^[2]
• Neurologic music therapy motor protocols — structured rehabilitation.^[8]

Tier B — mixed / early

Binaural beats — small lab effects, poor replication for broad claims.^[4] 40 Hz sensory stimulation — research lane separate from consumer gamma apps.^[9][10]

Tier C — unsupported marketing

Single Hz DNA repair, chakra frequency prescriptions, detox tones, water memory, 432 Hz miracle tuning without outcome trials.^[1][6]

How to listen safely

Use Sound Bubbles for comfort, focus, and sleep-adjacent floors — comfortable volume, mute when needed. Keep medical care medical.^[20]

Bottom line

This audit is educational, not personalized medical advice.^[1]

Companion listening in Sound Bubbles

Research above concerns clinical and laboratory sound — not a playlist guarantee. Sound Bubbles offers adjustable living gardens: spatial layers, coloured noise beds, Medical & Wellbeing rooms, and easy mute. Use recommended gardens as environmental support alongside medical care when appropriate.^[20]

Not treatment. See clinicians for diagnosis, medication, CBT, neurologic music therapy, or tinnitus programmes. Keep volume comfortable; stop if symptoms worsen.

Why this supports Sound Bubbles — not just "any ambient app"

Most ambient apps deliver one file. The studies above rarely study "a loop." They study continuous floors against irregular noise, unintelligible speech against memory tasks, nature scenes against stress markers, spatial streams against glued mashups, and slow environmental change against habituation.^{[9][14][22][23][24]}

Sound Bubbles maps onto those findings deliberately: brown/noise beds for masking floors, nature and library layers for restorative structure, distance/Falloff for speech intelligibility control, and TimeLine motion so the garden keeps the statistics of a place instead of the statistics of a four-minute loop.^{[12][15][16][25]} That is the practical reason the product feels different after the first hour — and the scientific reason the difference matters.

How to apply this inside Sound Bubbles

1. Open a related garden (or New Garden) and press Start playing so audio unlocks.^[9]
2. Expand Shape your soundscape → Sounds: set Master Volume, then Falloff while watching the audible-core guide.^[10]
3. Select a bubble; drag and scroll depth. Prefer raising one bubble's Volume over blasting the whole room.^[11]
4. Add library rain, nature, or noise layers; keep speech-like content distant — or remove it — when you need reading or coding focus.^[12]
5. TimeLine: choose Drift, Tide, or Orbit when you want the garden to keep evolving without grabbing attention.^[13]
6. Brown Noise tab: shape a warm floor, optionally Release as bubble so it becomes spatial.^[14]
7. Save gardens that still feel kind after an hour — public gardens should stay soft, not startling.^[15]

Limits, safety, and honest uncertainty

We do not claim Sound Bubbles replaces clinical care, sleep medicine, occupational health programmes, or psychiatric treatment.^[1][7] What the product does offer is a listening architecture that matches how hearing and attention actually work: layered sources, spatial distance, and slow change instead of one brittle loop.^[18][19]

If sound worsens symptoms, stop. If you need medical advice, see a clinician. If you want a softer room, open a garden, place the bubbles kindly, and stay honest about what sound can — and cannot — do.^[20][21]
