1Measurement precision

If traditional hearing enhancement systems are used, then they can provide basic audio amplification, but they fail to effectively isolate and amplify specific sound sources in noisy environments

Engineering Contradiction:

Improvesound source isolation accuracyVSAvoidbackground noise interference

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The audio spectrum is segmented into different frequency bands using multiple filters, allowing selective processing and amplification of specific sound sources while attenuating background noise in other frequency ranges

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different frequency bands are processed with different quality parameters - amplification is applied to bands containing speech or target sounds while attenuation is applied to bands containing background noise, creating locally optimized audio quality throughout the spectrum

Inventive Principle:

Principle #3Local quality
