Hearing Aid Audio Processing for Consistent Own-Voice Perception

The patent segments the audio signal processing into two distinct paths: one for external sounds (normal amplification) and one for the wearer's own voice (reduced amplification). By detecting voice signals and separating them from other audio signals, the system applies different amplification gains to different sound sources, thus maintaining reliable amplification for external sounds while preventing abnormal perception of the wearer's own voice.

The patent applies local quality by using different amplification gains for different signal types. Specifically, when a voice signal is detected, the system applies a first amplification gain (lower) to voice signals and a second amplification gain (higher) to other signals. This localized differentiation in amplification quality resolves the contradiction by tailoring the amplification characteristic to the specific signal being processed.

The patent implements dynamic amplification gain adjustment based on the detected signal type. The system continuously monitors incoming audio signals, detects whether they are voice signals, and dynamically switches between two amplification gain modes. This dynamic adaptation allows the hearing aid to optimize both processing efficiency and wearing comfort by selecting the appropriate gain level in real-time based on the current signal characteristics.

The patent changes the amplification gain parameter based on the detected signal type. When a voice signal is detected, the system switches from using a second amplification gain to using a first amplification gain (which is lower). This parameter change resolves the contradiction by adjusting the amplification level to match the specific processing needs of voice signals versus other signals, thereby improving both efficiency and comfort.

The patent segments the audio signal processing into distinct categories (voice signals versus other signals) and applies different amplification strategies to each segment. This segmentation approach maintains relative structural simplicity while eliminating unnatural voice perception by treating different signal types differently, thus resolving the contradiction between device simplicity and natural perception.

The patent applies local quality by using differentiated amplification gains for different signal types within the audio processing system. Instead of uniform amplification, the system applies a first amplification gain to voice signals and a second amplification gain to other signals, creating localized quality differences that eliminate unnatural perception while maintaining overall system simplicity.
