The first smart ring with a microphone
Every major smart ring -- Oura, Samsung Galaxy Ring, Ultrahuman, RingConn -- relies on motion and optical sensors alone. None of them include a microphone. Adola is the first to embed a PDM microphone directly in the ring, enabling snore detection, cough monitoring, and ambient noise tracking without relying on your phone.
The IM72D128 PDM microphone
What the microphone detects
Snoring episodes
Frequency, duration, and intensity of snoring throughout the night. Correlated with SpO2 data to flag potential sleep-disordered breathing patterns.
Cough events
Nighttime coughing frequency tracked over days and weeks. Useful for monitoring respiratory illness progression or allergies.
Ambient noise levels
Average noise level in your sleep environment. High ambient noise correlates with lighter sleep stages and more frequent awakenings.
Privacy by design
Audio from the microphone is processed entirely on the ring's nRF52833 processor. Only classified event data (snore count, duration, intensity) is transmitted to the app. Raw audio is never stored and never leaves the ring.
Why hasn't anyone else done this?
Power and space. A MEMS microphone draws additional current and takes up board space in an already cramped form factor. Adola uses a duty-cycled sampling approach -- the microphone activates in short bursts during sleep, processes audio locally, and returns to sleep mode. This keeps total power consumption within the 17 mAh battery budget while maintaining 5-7 day battery life.
