Hearing Device Active Noise Cancellation TRIZ Cases
- ANR Headphones Tap Control via Current Detection
Acoustic noise reduction headphones detect user taps through current consumption patterns to adjust audio settings without physical buttons.
- Active Noise Cancellation Coefficient Update Mechanism
Digital signal processor writes new noise cancellation coefficients into an idle storage module while the active noise cancellation module continues processing audio signals.
- Ear Biometric SNR Improvement via Dual-Function Audio Stimulus
Dual-function audio stimuli improve signal-to-noise ratio in ear biometrics by aligning measurements with ear resonances during media playback.
