Innovation Solution
A system and method enabling users to autonomously fit hearing aid parameters using artificial intelligence, allowing hearing tests on headphones if no aid is available, and utilizing a mobile device microphone to record environmental sounds for improved test results, with adjustments made at the user's convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user travels to a professional's office for hearing aid adjustment, then professional assistance and accurate fitting are improved, but convenience and time consumption deteriorate
Solution Approach 1:
The hearing aid system performs self-diagnosis and self-adjustment by autonomously conducting hearing tests, analyzing user feedback, and automatically modifying parameters without requiring professional assistance. The system serves itself by using its own resources (microphone, processor, memory) to complete the fitting process.
Solution Approach 2:
A mobile device serves as an intermediary between the hearing aid and the user. The mobile device provides the interface for hearing tests, displays results, and facilitates communication between the user and the hearing aid system, enabling remote adjustment without professional presence.
2Manufacturing precision
If a user travels to a professional's office for hearing aid adjustment, then accurate fitting is improved, but time consumption and expense deteriorate
Solution Approach 1:
The system performs preliminary hearing tests and parameter adjustments before the user needs the hearing aid. By conducting tests in advance and pre-configuring parameters, the system eliminates the need for time-consuming in-office adjustments and allows users to receive accurate fitting remotely.
Solution Approach 2:
The patent replaces the mechanical process of in-office adjustments with electronic and computational methods. Digital signal processing, automated parameter optimization, and electronic communication substitute for the physical presence and manual adjustment traditionally required in professional offices.
3Adaptability or versatility
If hearing tests are conducted without a hearing aid, then accessibility is improved, but test quality deteriorates
Solution Approach 1:
The system dynamically changes test parameters based on whether the user has a hearing aid. When no hearing aid is present, the system adjusts frequency ranges, sound levels, and test protocols to accommodate different hearing conditions, maintaining test quality across diverse user scenarios.
Solution Approach 2:
The hearing test system is dynamic and adapts its methodology based on real-time detection of the user's hearing aid status. The system switches between different test modes (with-aid and without-aid modes) and adjusts parameters accordingly, providing both accessibility and measurement precision.
4Measurement precision
If environmental sounds are recorded during hearing tests, then test accuracy is improved, but device complexity increases
Solution Approach 1:
The mobile device serves multiple functions: it acts as the interface for hearing tests, provides audio recording capabilities, displays results, and facilitates communication with the hearing aid. By leveraging the mobile device's existing multi-functional capabilities, the system avoids adding complexity while improving test accuracy.
