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.
💤 For snorers & their partners
Snoring Isn't a Habit. It's Airway Resistance. And Now It's Fixable.
Research shows snoring correlates directly with nasal airway resistance and facial anatomy. SONU uses AI to map your unique anatomy and opens your airway with personalized acoustic therapy — no drugs, no surgery, no strips.

The real cause
You Don't Snore Because You're Lazy. You Snore Because Your Nasal Airway Is Too Narrow.
Snoring happens when air flows through a partially obstructed upper airway, causing the surrounding soft tissue to vibrate. And the nose — which accounts for approximately half of total respiratory airflow resistance — is often the first and most significant point of obstruction.
When nasal resistance increases, your body compensates by routing air through the mouth. But oral breathing creates 2.5× higher upper airway resistance during sleep compared to nasal breathing — collapsing the pharyngeal airway further and intensifying snoring.
Self-reported nocturnal nasal obstruction makes you up to 3× more likely to be a habitual snorer and experience daytime sleepiness. Nasal obstruction is a recognized, modifiable risk factor for sleep-disordered breathing.
— Georgalas, Eur Arch Otorhinolaryngol (2011); Young et al., J Allergy Clin Immunol (1997)Here's the critical insight most people miss: your nasal airway resistance is determined by your unique anatomy — the size and shape of your sinus cavities, the geometry of your nasal passages, the state of your mucosal lining. That's why generic solutions like strips and sprays work for some people and not others. The anatomy is different for everyone.
The research
What Peer-Reviewed Science Says About Snoring, Airway Resistance & Nasal Anatomy
📄 Snoring Severity Correlates with Nasal Airflow Resistance
Hoffstein et al. quantitatively measured snoring in 109 patients (50 apneic, 59 non-apneic) and correlated it with upper airway properties. They found a significant correlation between snoring severity and nasal airflow resistance in both groups.
→ Hoffstein et al., Chest (1988)📄 Oral Breathing Creates 2.5× Higher Airway Resistance During Sleep
Fitzpatrick et al. confirmed that during sleep, upper airway resistance during oral breathing is 2.5 times higher than nasal breathing. Nasal obstruction forces mouth breathing, which further collapses the pharyngeal airway — a vicious cycle that amplifies snoring.
→ Fitzpatrick et al., Eur Respir J (2003); cited in JCSM📄 The Nose as the "First Boundary" of the Upper Airway
Georgalas' comprehensive review established that nasal obstruction contributes to sleep-disordered breathing through multiple mechanisms: the Starling resistor model, unstable oral airway, disruption of the nasal ventilatory reflex, and reduced nitric oxide production. Improving nasal resistance — medically, surgically, or with dilators — improves sleep quality.
→ Georgalas, Eur Arch Otorhinolaryngol (2011)📄 Upper Airway Resistance Syndrome & Anatomical Factors
UARS involves heightened airway collapsibility exacerbated by anatomical factors: retrognathia, narrow nasal passages, and craniofacial structure. A narrow nasal passage is a key risk factor, and nasal breathing optimization is a front-line management strategy.
→ StatPearls: Upper Airway Resistance Syndrome (2025)The bottom line: Snoring is a physics problem. Air resistance in the nasal passage → mouth breathing → pharyngeal collapse → tissue vibration. Reduce nasal resistance, and you interrupt the cascade at its origin.
Why SONU is different
Generic Solutions Ignore the Thing That Matters Most: Your Anatomy Is Unique
Nasal strips apply a one-size-fits-all mechanical force. Sprays deliver the same chemical regardless of your sinus structure. But your nasal airway resistance depends on the specific geometry of your sinuses and passages — and that geometry is as unique as a fingerprint.
SONU is the first device that personalizes treatment to your anatomy:
AI Anatomical Mapping
Your phone camera captures facial landmarks. SONU's algorithm calculates the volumes of your maxillary sinuses, ethmoid sinuses, and nasal cavity — then determines your optimal resonant frequencies.
Personalized Resonant Frequencies
Two bone-conduction transducers deliver acoustic vibrations calibrated to your sinuses (80 Hz – 16 kHz). The resonance is specific to you — not a generic frequency that might work for some faces and not others.
Addresses Root Cause, Not Symptoms
SONU works through vasoconstriction (reducing mucosal swelling), mucociliary clearance (draining mucus), and autonomic modulation — mechanistically reducing nasal resistance rather than masking the problem.
15-Minute Pre-Sleep Ritual
Use SONU before bed. The experience is soothing and spa-like — many users say it becomes the most relaxing part of their evening routine. Then breathe freely through your nose all night.

The bigger picture
It's Not Just About the Noise. It's About Sleeping Together Again.
"Sleep divorce" — couples retreating to separate rooms because of snoring — is at an all-time high. And the emotional toll is real: resentment builds, intimacy suffers, and both partners end up exhausted.
But the snorer isn't choosing to snore. It's a structural problem — airway resistance dictated by anatomy and inflammation — and it deserves a structural solution, not blame.
SONU gives both partners something to be hopeful about: a 15-minute routine that addresses the root physics of snoring, backed by clinical evidence, with zero risk and zero side effects.
