In The Ear Hearing Aids TRIZ Cases
- ITE Hearing Aid Gain Control for Comb-Filter Suppression
Correlation between environmental and eardrum signals guides gain changes that suppress comb-filter artefacts and improve speech clarity.
- Piezoelectric Eardrum Transducer Assembly for Low-Occlusion Hearing
Direct piezoelectric eardrum coupling replaces coil-magnet driving to cut occlusion, discomfort, and energy loss in contact hearing.
- In-Ear Hearing Aid Transducer Layout for Embedded Sensors
By placing sensors inside the transducer air volume, this hearing aid case adds physiological monitoring without increasing in-ear size.
