VoqX AI Infrasound Smart Stethoscope

Sanolla is a medical device company founded in 2016 that develops AI-based infrasound auscultation technology. It addresses the limits of the acoustic stethoscope, largely unchanged for 200 years, which cannot capture low-frequency body sounds that carry early signs of heart failure, valvular disease and lung conditions.

VoqX captures heart and lung sounds including infrasound below 30 Hz, shifts them into the audible range with 40x amplification and active noise cancellation, and runs real-time AI analysis on an embedded processor with a built-in display. Its algorithms were trained on more than 100,000 auscultation recordings from clinical institutions in the EU and US. The device records and stores sound files, measures heart rate and connects via Bluetooth to an app for remote care. A companion device, PyXy, adds ECG and SpO2 for home monitoring of heart failure and COPD. Users are physicians, nurses, paramedics, hospitals, EMS and home care providers.

• Infrasound BOOST: captures body sounds below 30 Hz and shifts them into the audible range.
• Real-time AI analysis: embedded algorithms trained on more than 100,000 auscultation recordings.
• Heart and lung modes: separate modes with 40x sound amplification and active noise cancellation.
• Built-in display: real-time BPM measurement and on-device results.
• Recording and connectivity: stores sound files and connects via Bluetooth to an app for remote care.
• PyXy home monitor: combines infrasound auscultation with ECG and SpO2 for CHF and COPD patients.

District hospitals and commune health stations in Vietnam could use VoqX to screen for valvular disease and heart failure before referral. Emergency departments and ambulance teams could auscultate reliably in noisy settings. Medical universities could use recorded sound files for clinical training and simulation.

Gives clinicians AI-assisted decision support at the point of care, helping detect heart and lung abnormalities that a traditional stethoscope misses. 40x amplification and noise cancellation keep auscultation usable in noisy emergency rooms and ambulances. Recorded sound files improve documentation and allow remote review. The company reports pilot studies showing better identification of cardiac anomalies and respiratory issues, supporting faster triage and fewer unnecessary imaging tests.

Primary care and emergency services are adopting digital stethoscopes and AI decision support to compensate for limited access to echocardiography and specialists. In Vietnam, commune health stations and district hospitals handle large numbers of heart failure and COPD patients with few cardiologists, which favours low-cost point-of-care screening tools that can share recordings with specialists.
