Hearing Device Active Noise Cancellation TRIZ Cases

Compact 4-bit non-uniform weight encoding cuts memory and compute load for neural hearing aids while preserving network performance.

Internal earbud microphones estimate ear canal impedance and predict eardrum sound pressure to personalize playback and improve ANC.

Synthetic bone-conduction signals and transfer functions cut training data collection while improving speech enhancement in wearable audio.

Coarse noise analysis triggers bandwise gain control in a hearing aid to suppress stationary noise while preserving speech and music.

4-bit non-uniform weight encoding cuts memory and compute load in hearing-device DNNs while preserving signal processing performance.

When playback shifts to a newly connected device, specialized functions on the original device are managed to avoid sensory disruption.

A speaker-port microphone tracks acoustic path changes to detect poor fit or debris and alert users before audio quality drops.

An angled microphone module and selective waterproofing keep moisture out while preserving earbud sound quality, volume, and ANC performance.

Participant-aware antinoise cancels non-participant voices in XR shared spaces while preserving clear communication through directional audio.

Band-wise suppression plus low-resolution noise analysis curbs stationary noise in hearing instruments without speech comodulation.

Vent cutoff frequency steers hearing aid noise reduction and speech enhancement settings to improve initial fitting and preserve target audio.

Vent cut-off frequency steers hearing aid fitting to tune noise reduction and speech enhancement without degrading target audio.

Shared filter parameters let sidetone reuse the noise reduction path, cutting latency and computation while preserving clear call audio.

Pulsed ultrasonic wavelets let a wearable audio device detect on-head or open-air state using its driver and microphone instead of extra sensors.

Shared filter parameters let sidetone reuse noise-reduction processing to cut latency, lower compute load, and preserve natural call feedback.

A compliant sound guide routes audio from extra-aural speakers into the ear, improving privacy and sound quality with attachment-based mode switching.

Multiple inner and outer sensors plus ML masking combine differently degraded audio to suppress competing speech and clarify user speech.

Mesh openings and ear-tip extensions block wax and dust at earpiece ports while preserving acoustic coupling and reducing artefacts.
