Hearing Aids Signal Processing TRIZ Cases
- Dual-Path Neural Network Hearing Aid Processing for Speech Isolation
A controller switches DSP and neural network paths to improve speech isolation in noise while conserving hearing aid power.
- Auditory Prosthesis Audio Training With Real-Time Sound Identification
External microphones and sound recognition provide audible or visual sound identities for real-time auditory rehabilitation.
- Hearing Aid Accelerometer-Based Lost Device Detection
Accelerometer data comparison prevents hearing damage by enabling sound output only when stationary.
- Hearing Aid Audio Signal Processing with Dynamic Delay
A hearing aid processor segments audio signals into distinct processing schemes to manage transmission timing.
- Hearing Aid Noise Reduction via Power-Constrained Spectral Estimation
Power-constrained maximum likelihood estimator prevents negative spectral components and speech overestimation in hearing aid noise reduction.
- Hearing Device Head Movement Detection via Orthogonal Acceleration
A hearing device uses an orthogonal acceleration sensor to detect head yaw movements for accurate conversation participant identification.
- Hearing Aid Noise Suppression via External Transducer Transfer Function
A hearing aid uses an external transducer signal filtered by a relative transfer function to estimate target audio.
