Super Nasal-Oral Ratiometry System

SNORS detects nasal and oral airflow during speech to provide a non-invasive objective assessment of velopharyngeal insufficiency (VPI). It uses a lightweight dual chamber mask that is held over the nose and mouth. A soft silicone cuff moulds to the contours of the face providing a comfortable air tight seal. Rapid response airflow sensors and microphones are contained in both the nasal and oral chambers of the mask to enable aerodynamic and acoustic analysis.
