SONU is indicated for the relief of moderate to severe nasal congestion due to allergic and non allergic rhinitis. SONU is a treatment to be used at home by individuals 12 and older. Individual results may vary.

The Breakthrough Discovery
People with Deeper Nasal Cavities Seek Congestion Treatment Far More Often
A landmark study in the International Forum of Allergy & Rhinology found that the ratio of nasal cavity depth to height (DHR) is significantly associated with how frequently people treat their nasal congestion.
After propensity score matching across 284 users, the high-DHR group showed an 18.3 percentage point higher engagement rate with acoustic resonance therapy. The likely explanation: deeper nasal cavities provide greater surface area for allergen deposition, resulting in more severe symptoms.
This is the first study to link a measurable anatomical characteristic to allergy treatment behavior at scale.

From Selfie to Personalized Allergy Relief in Seconds
1
Scan Your Face
Your smartphone camera creates a 3D facial mesh using your selfie, mapping craniofacial landmarks to estimate internal nasal cavity dimensions — no CT scan, no radiation, no clinic visit.
2
AI Maps Your Anatomy
Machine learning algorithms correlate your external facial geometry to internal sinus dimensions with under 10% error vs. CT scans — validated in a peer-reviewed IEEE study.
3
Personalized Treatment
SONU, an FDA-cleared wearable headband, delivers acoustic resonance therapy calibrated to your unique nasal anatomy. No drugs. No side effects. Just targeted relief.
Why This Matters Now
2026 Is on Track to Be the Worst Allergy Season in Years
Climate change has made each successive allergy season longer, more intense, and earlier. Tree pollen is already peaking across the southern U.S. — weeks ahead of the historical norm. For the first time, technology can explain why some people suffer more than others.
