Digital ANC - Augmented Hearing

ams Digital Augmented Hearing Solutions enable a new era of audio devices in wireless and true wireless earbud designs. The Digital ANC device supports ‘Hear what you want to hear’ functionality for loose fit earbuds. It tunes out ambient noise through market leading Active Noise Cancellation (ANC) performance >40dB and simultaneous tunes in speech and music with natural and boosted transparency modes.
The technology supports all 3 types of ANC topologies (feed-forward, feed-back and hybrid) as well as ams unique Automatic Leakage Compensation (ALC) for loose fit earbuds. ALC end users’ benefit from an optimized and stable ANC performance no matter how tightly or loosely the earbud fits into the user’s ear.
The technology also supports “Automatic Preset Selection” (APS), which automatically adapts the ANC performance to different ambient noise environments.
