AutoSense OS™

AutoSense OS and AutoSense Sky OS: the next generation of technology automation

Hearing aids with AutoSense OS recognize and automatically adapt to more of your client’s listening situations than ever before. AutoSense OS accurately captures and analyzes the sound environment, then precisely blends feature elements from multiple programs in real time to provide a seamless listening experience.

AutoSense Sky OS has been specifically designed to ensure that kids and teens have an optimal listening experience in their unique listening situations. These include the classroom, on the playground, when listening to music or with their family. For example, the dedicated pediatric classifier leads to greater comfort in the presence of loud speech and yelling, as compared to the AutoSense for adult system1.

Use of AutoSense OS, versus use of manual programs, has been shown to improve speech understanding by 20%. This occurs when listening to speech in challenging listening environments, namely in noise, loud noise, and in a car.

AutoSense OS is the automatic operating system, introduced with Phonak Venture, that provides improved sound recognition in listening situations by analyzing incoming sounds in real-time and automatically activating an appropriate blend of optimized gain settings, programs, and features specific to various listening environments. AutoSense OS identifies listening situations with accuracy and adapts with precision.


The enhanced identification of different listening situations and seamless automatic blending provides a more natural and optimal hearing experience. This reduces manual program changes, improving ease of use.


AutoSense OS can be perfectly tailored to your individual client’s needs in Phonak Target by adjusting its overall settings or the individual program settings.
