Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual test process is used by professional hearing aid dispensers, then hearing aid fitting can be completed, but the test process becomes complex and accuracy decreases
Solution Approach 1:
The system enables automated hearing loss testing and compensation through the terminal device, eliminating the need for manual testing by professional dispensers. The terminal automatically performs hearing detection, generates test signals, collects feedback, and calculates compensation parameters, allowing the system to serve itself without human intervention in the testing process.
Solution Approach 2:
The patent replaces the manual mechanical testing process with an automated electronic system. The terminal device uses software algorithms and automated signal generation to perform hearing tests, substituting the manual operations of professional dispensers with computerized automation, thereby improving both accuracy and simplifying the process.
2Productivity
If manual fine-tuning and testing are performed, then hearing aid fitting is completed, but the process time increases
Solution Approach 1:
The terminal device performs preliminary hearing detection and automatically generates compensation parameters before the actual hearing aid fitting. By conducting the hearing test and calculating compensation values in advance through automated processes, the system prepares all necessary parameters beforehand, eliminating the need for time-consuming manual fine-tuning during the fitting process.
Solution Approach 2:
The system implements automated feedback collection during hearing tests, where the terminal receives feedback instructions from the hearing-assistive device and uses this feedback to automatically adjust and optimize compensation parameters. This closed-loop feedback mechanism enables rapid iteration and optimization without manual intervention, significantly reducing the time required for fitting.
3Speed
If automated terminal-based testing is implemented, then test speed increases, but system complexity increases
Solution Approach 1:
The terminal device is designed to perform multiple functions: it generates test signals, collects hearing feedback, processes audio data, calculates compensation parameters, and communicates with the hearing-assistive device. By consolidating all these functions into a single multi-functional terminal system, the patent avoids the need for multiple separate complex devices while achieving automated high-speed testing.

AI summary
A hearing-assistive device-based hearing loss compensation method is performed by the terminal. A communication connection is established between the terminal and a hearing-assistive device to be fitted. The method includes: performing a hearing loss test on a hearing-assistive object to obtain a hearing loss test result; performing hearing loss compensation based on the hearing loss test result to obtain a hearing loss compensation gain; and sending the hearing loss compensation gain to the hearing-assistive device, where the hearing-assistive device is configured to perform hearing loss compensation on a first speech signal based on the hearing loss compensation gain to obtain a second speech signal.
