AutoSense OS™

When your hearing aids adapt to every sound automatically, life is on

Sound is all around and changes constantly depending on where you are. What makes Phonak hearing aids so special is their unique operating system called AutoSense OS. All you have to do is turn them on and the rest is automatic.

Fully automatic for effortless listening everywhere

AutoSense OS is designed with your everyday listening situations in mind, seamlessly adapting to sounds wherever you are. It senses your surroundings and adjusts your hearing aids every step of the way. It analyzes the sounds around you every 0.4 seconds and can identify whether you’re in a noisy restaurant, car, concert hall or at home. It then draws upon multiple features blending them to create over 200 distinct settings to precisely match your exact sound environment. Without having to adjust your hearing aids manually, you can enjoy unmatched hearing performance…wherever life takes you.1
