Some details
Bruxlab, currently renamed as Sleep.ai, is a Dutch healthcare startup. Being a dentist, our client, Michiel Allessie, has been studying the teeth grinding (or so-called bruxism) and its impact on the health.
AltexSoft developed an iOS app running in the background during the night and capturing the sounds made by users while sleeping. Based on a complex algorithm, the system would then be used to isolate grinding sounds
and tabulate the score. The reports are then further forwarded to a dentist for treatment.Employing data analytics and machine learning techniques, AltexSoft team created an algorithm, able to distinguish the teeth grinding from other noises. Our data scientists built a neural network and used 6,000 audio samples to solve the noise classification problem. For every sample the team was able to extract attributes, of the grinding. Our algorithm has reached up to 80% accuracy in recognition (with the accuracy growing as more samples are analyzed).
