Occlusion Effect Electronic Compensation TRIZ Cases
- Hearing Aid Subsonic Filter for Occlusion Suppression
Defined subsonic filtering removes jaw motion energy below 10Hz to eliminate occlusion cancellation artefacts while preserving dynamic range.
- Bi-Stable Balanced Armature Receiver for Acoustic Valve Switching
A bi-stable balanced armature receiver integrates a second deflectable armature to actuate an acoustic valve within the transducer housing.
- Binaural Hearing Device Active Occlusion Cancellation
Binaural hearing device system uses excessive level detectors to adjust signal processing and prevent distortion from high amplitude cancellation.
- Hearing Device Own-Voice Detection Using Ear Canal Microphone Filtering
A hearing device computes the difference between an ear canal microphone signal and a filtered receiver output to detect user own-voice presence.
