For Snoring & Obstructive Sleep Apnea · Without Mask or Splint

Quiet nights without a CPAP mask or dental splint

With 15 minutes of daily training on the Medical Didgeridoo®, Silent Sleep Training® strengthens slackened throat muscles. This keeps upper airways stable at night against snoring and mild-to-moderate obstructive sleep apnea.

Airway Biomechanics

Why active muscle training keeps upper airways open at night

Anatomical comic cross-section comparison: Left shows narrowed airway from slackened throat muscles with snoring turbulence, right shows open airway with smooth airflow after Silent Sleep Training
Before · Slackened Musculature

During sleep, a slack soft palate and tongue base fall backward – narrowing the airway and causing snoring vibrations and breathing pauses.

After SST · Toned & Clear Airway

The training strengthens pharyngeal muscles. Airways stay stable during sleep and air flows quietly without a mask or splint.

Inseparable Biofeedback System

Medical Didgeridoo®
Device and App Working Together

The Medical Didgeridoo® generates calibrated air resistance. The sensor and app measure during practice whether pressure and tone frequency reach deep pharyngeal muscles. Blowing into the device without app feedback produces no training effect.

Daily Training Routine

Three months to build strength, minutes to maintain it

Just like physical muscle conditioning, Silent Sleep Training® follows two clear phases: after three months of training, a few short sessions per month keep toned pharyngeal muscles stable at night.

15 minutes of active daytime training – sleep mask-free without hoses or splints at night.

Science & Suitability

Clinically Validated
Two Landmark Studies
and Clear Boundaries

Pharyngeal muscle training was researched in two clinical trials with the University of Zurich and published in The British Medical Journal, honored in 2017 at Harvard University with the Ig Nobel Prize for groundbreaking medical innovation.

🩺 Medical Advisory

Dr. med. Marcus Hesse (Sleep Specialist & Pulmonologist): «For me, Silent Sleep Training® is often the first-line therapy of choice for sleep apnea and snoring.» We collaborate closely with pulmonologists and sleep laboratories.

Who is the training designed for:

  • You experience chronic snoring or mild-to-moderate obstructive sleep apnea (OSA).
  • You are looking for a mask-free alternative or struggle with CPAP masks or oral appliances.
  • You are ready to practice 15 minutes daily for 3 months during the training phase. Afterwards, 2 to 4 sessions per month are enough.

Not suitable or only after prior medical clearance:

  • Pure central sleep apnea (where breathing cessation is neurological rather than pharyngeal).
  • Severe obstructive sleep apnea without prior consultation with a pulmonologist.
  • Acute inflammation or unhealed wounds in the oral cavity or pharynx.
  • Pregnancy

Important medical note: No healing promise. Silent Sleep Training® is an active training therapy designed to strengthen airway musculature and a certified Class I medical device. If diagnosed with sleep apnea, always consult your physician before use. Never discontinue prescribed therapies (such as CPAP) on your own.

University Hospital Zurich & The BMJ
The BMJ

Two Clinical Trials on Efficacy & Mechanism

1. Clinical Efficacy (The BMJ): A randomized controlled trial led by Prof. Dr. Milo Puhan demonstrated statistically significant reductions in AHI and daytime sleepiness.

2. Anatomical Mechanism (MRI Study): MRI scans showed a reduction of fatty tissue surrounding the upper airways and a more stable pharyngeal passage.

3. Global Evidence: Over 12 international studies corroborate the efficacy of myofunctional pharyngeal training.

Award: Honored in 2017 at Harvard University with the Ig Nobel Prize for research that makes people laugh, then think. The training strengthens throat muscles without medication and without surgery.

The Founder · Alex Suarez

From His Own Bedroom
to The British Medical Journal

Alex Suarez was in his mid-30s and working as a martial arts instructor when his wife pushed him out of bed at night – because he had stopped breathing in his sleep.

Alex Suarez – Founder & Inventor
Alex SuarezFounder & Inventor

«Before I use this machine for the rest of my life, I would rather die 20 years earlier.»

Alex Suarez to his physician when returning the noisy CPAP machine after two sleepless weeks
  1. 01Höhenklinik Wald

    Moderate sleep apnea diagnosis – and 14 sleepless nights

    After stopping breathing at night, his family doctor referred him for an overnight sleep study at Höhenklinik Wald. He returned home with a diagnosis of moderate sleep apnea and a clear medical verdict: a CPAP mask on his face every night for life. He tried it for two weeks. Neither he nor his wife could sleep over the noise of the blower, and after 14 days he brought the machine back.

  2. 02Martial Arts & Anatomy

    Asking why the airway collapses

    Before leaving the clinic, he asked his doctor to explain the exact physical mechanism: during sleep, muscles in the throat and pharynx slacken and close the airway. Drawing on his background as a martial arts instructor, he went home with one practical question – whether there was a way to actively train those specific muscles.

  3. 03Seminar in Ibiza

    A custom playing technique and a 3-month pact with his doctor

    At a seminar in Ibiza, he watched a student play the didgeridoo and noticed the student’s throat visibly moving. Hopeful, he asked whether the student snored or had sleep apnea – and learned that the student snored too. Undeterred, Alex Suarez developed his own targeted playing technique and agreed on a three-month self-trial with his attending doctor: 15 to 20 minutes of daily training, followed by a repeat sleep-lab measurement.

  4. 04USZ Zurich & The BMJ

    Discharged free of sleep apnea – from single case to clinical trial

    After three months, Alex Suarez spent another night in the sleep lab and was discharged the next morning free of sleep apnea. For him, his personal problem was solved. Soon after, the physicians contacted him to ask whether he would lead the training in a formal clinical trial to test if his result was a fortunate exception or reproducible across patients. Conducted with the University Hospital Zurich (University of Zurich) and Höhenklinik Wald, the trial produced significant results published in The British Medical Journal, followed by a second MRI study showing the structural changes inside the throat.

Personal account of founder Alex Suarez. Individual outcomes vary; Silent Sleep Training® is an active training therapy and not a promise of cure.

Personal Experiences

How Restful Nights
Return to Daily Life

Three documented patient cases: from keeping a driving licence without a CPAP mask to verified sleep-lab results.

Licence PreservedAHI 24 → 5,9
“My AHI dropped from 24 to 5.9 – training with the Medical Didgeridoo® was fully accepted by the road traffic office, so I don’t need a CPAP mask to keep my driving licence!”

I was constantly tired and drained, so my doctor ran diagnostic tests. The result: sleep apnea with 24 pauses per hour. I was told I would have to wear a CPAP mask for the rest of my life. I quickly realized I couldn’t sleep with those devices – I felt suffocated.

A good friend recommended Silent Sleep Training®. At first, I started and lost motivation after a month. But early this year, I committed and pushed through for 5 months. The result is magnificent:

I had my sleep apnea re-tested for a traffic medicine assessment: my AHI dropped from 24 to 5.9 episodes – finally symptom-free in daily life! No more daytime fatigue, deep sleep, and renewed energy. Best of all: training with the Medical Didgeridoo® was fully accepted by the traffic authority! I can recommend the Medical Didgeridoo® to everyone!

Long-term SuccessAHI 3,32 · Age 81
“The Medical Didgeridoo® is the BEST thing there is for me. After more than three years, the clinical sleep follow-up continues to show an outstanding response to therapy with the Medical Didgeridoo®.”

Dear Mr. Suarez, the Medical Didgeridoo® is simply the BEST solution for me.

I ordered the Medical Didgeridoo® on 23.06.2020. On 14.01.2021, I celebrated my first breakthrough (AHI 3.32). For driving safety reasons (traffic authority), an additional voluntary AHI check was measured on 30.08.2021: another superb result!

From then on, I continued training with the Medical Didgeridoo®. The clinical sleep assessment on 17.08.2023 demonstrated a continued excellent response to therapy with the Medical Didgeridoo®. I am 81 years old and will report for my next regular check in two years.

Doctor & PatientSleep Lab: AHI Normalized
“The sleep clinic specialist was completely astonished: ‘Dr. Sobel … You don’t have any sleep apnea anymore!’ As both a patient and a physician, I stand wholeheartedly behind this natural method.”

As a sports medicine physician, I had always maintained peak physical fitness, yet severe sleep apnea robbed me of all quality of life. I suffered from relentless exhaustion and dangerous ‘brain fog’. The prescribed CPAP machine was intolerable for me, and invasive surgery was out of the question. Then I discovered the training with the Medical Didgeridoo® and practiced online with Alex.

From a medical standpoint, it made total sense: targeted resistance training for slackened airway muscles. Within months, the fog lifted and my vitality returned. The ultimate triumph came years later during a re-evaluation in the sleep lab. The physician was utterly astonished: “Dr. Sobel … you have no sleep apnea anymore!”

This training completely transformed my life. As both a patient and a medical doctor, I stand wholeheartedly behind this natural, permanent therapy and recommend it to anyone seeking freedom from the CPAP mask.

Which payment methods (TWINT, Klarna invoice, cards) are accepted?

You can pay securely via Stripe using TWINT, Klarna (Invoice), Apple Pay, Google Pay, Visa, or Mastercard.

How much training is realistically required?

The Silent Sleep Training® program requires 15 minutes a day, 6 days a week for an initial 3-month build-up phase. Afterward, 2–4 monthly 15-minute sessions maintain your toned airways.

What is included in the package?

The kit includes the exact same high-quality next-generation hardware: the Medical Didgeridoo® (43 cm, 350 g, dishwasher-safe, CE Class I Medical Device) including connection cable (USB-C) for smartphone, tablet, and computer, plus 12 months of app access with onboarding course and training games.

How does game-based biofeedback work?

The Medical Didgeridoo® connects to the app via connection cable. The app analyzes your tone in real time. Using the correct technique, you control engaging games: scoring points confirms your airway muscles are being trained effectively.

Is SST suitable for obstructive sleep apnea?

Clinically studied for snoring and mild-to-moderate OSA. Always discuss your condition with your sleep physician; never alter prescribed therapies without guidance.

What is the difference between Basis and Premium?

Both packages contain the exact same high-quality next-generation hardware: the Medical Didgeridoo® (43 cm, 350 g, dishwasher-safe, CE Class I Medical Device) including connection cable (USB-C). The difference lies solely in the depth of app guidance: Basis includes 12 months of standard app access with onboarding course, 3 visual training guides, core games, and nightly snore tracking. Premium provides 12 months of premium app access with a conversational AI personal coach, 10+ training games, advanced sleep trend analytics, free access to founder webinars, and prioritized support.

Can I upgrade from Basis to Premium later?

Yes, you can upgrade from Basis to Premium at any time during the active 12-month period. You only pay the difference and immediately gain access to all Premium features.

Can I use the Medical Didgeridoo® without an app subscription after the first 12 months?

No. The Medical Didgeridoo® provides calibrated air resistance, but the sensor and app verify whether pressure and tone engage deep pharyngeal muscles properly. Without feedback from the app, there is no controlled training effect. Your first 12 months are included in the purchase price; from year 2 onward, app access costs CHF 10 per month (CHF 120 per year in the Basis plan, cancellable anytime before renewal).

Do I need musical experience or read sheet music?

No. You are not playing melodies and need no musical background or sheet music. The onboarding course in the app teaches the correct breathing and tone technique within minutes.

Can the training program be used by multiple people?

For regulatory compliance and hygiene standards as a certified medical device, Silent Sleep Training® is strictly personal and can only be activated and used by one individual. The Medical Didgeridoo® and individual progression in the app are customized for each user.
