Phonak Slim Hearing Aids Technology

Phonak Slim runs on the PRISM (Processing Real-time Intelligent Sound Management) chip and includes motion sensors. PRISM runs the new AutoSense OS™ 5.0 software, which enables SmartSpeech technology.

Phonak Autosense OS 5.0

Trained with artificial intelligence, Autosense is software that automatically changes the programs and settings of the hearing aid. As a hearing aid user moves into different listening environments, Autosense automatically loads the best program, changes the volume, and adjusts the hearing devices’ advanced features.

Speech Enhancer


Speech Enhancer is an adaptive feature that enhances a soft speech signal in quiet situations. Hearing aid wearers experience reduced listening effort in quiet.







Dynamic Noise Cancellation



Phonak Slim hearing aid wearers can benefit from reduced listening effort in noise thanks to Dynamic Noise Cancellation. The system works with Phonak’s adaptive beamformer and the motion sensor.





Motion Sensor Hearing



Motion Sensor Hearing Detects if the user is stationary or moving and how noisy the surroundings are. AutoSense OS™ 5.0 then automictically adjusts the hearing aids setting to ensure optional hearing.





SteroZoom 2.0


StereoZoom 2.0 enables the hearing aid microphones to focus on speech from the front and is activated in noisy listening environments.








With SpeechSensor, users can hear from the back and the sides. This automatic feature detects the primary speech source and adjusts its microphone modes to ensure the client has more access to speech from the side and back.
