Hearing Aids Signal Processing TRIZ Cases
- Hearing Aid Signal Processing with Dual Compressor Segmentation
Segmenting compression into independent points preserves fine-tuning effects against adaptive processing interference.
- Binaural Hearing System Noise Reduction via Interaural Data Exchange
A binaural hearing system transmits noise estimates between devices to improve signal processing accuracy.
- Hearing Aid Directional Microphone Adaptive Delay Control
Cross-correlation analysis determines effective time delays between microphone signals to maintain directivity performance despite wearing position deviations.
- Hearing Aid Feedback Control Using Correlation Detection
A hearing aid feedback control system calculates a correlation measure between input and output signals to distinguish external tones from feedback.
- Hearing Aid Guide Unit Between Tragus and Antitragus
A guide unit anchors a hearing device between the tragus and antitragus to stabilize the ear part.
- Binaural Hearing Aid Spatial Audio Processing
A binaural hearing aid device adjusts time delay and sound level of wireless rear signals to create surround sound.
- In-Ear Subvocalization Recognition via Vibration Sensing
An in-ear device captures subvocalized utterances using internal sensors to interpret mechanical vibrations as digital commands.
- Self-Fitting Hearing Device Signal Calibration via Feedback
Wireless communication device adjusts calibration signals using feedback from the hearing device to ensure accurate self-fitting.
- Hearing Aid Speech Intelligibility via Remote Text-to-Speech Processing
A hearing aid system uses remote text-to-speech synthesis to convert audio streams into intelligible speech for users.
- Audio Device System Speech Content Comparison for Noise Reduction
Audio device system compares speech content to isolate desired speaker signals, suppressing background noise without complex sensors.
