Hearing Test System for Verifying Credibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional assistive listening devices fail to adapt to individual hearing impairments effectively, leading to suboptimal performance and limited usability across varying hearing conditions, as they are not adjustable to specific user needs and cannot handle external sounds properly.
Innovation Solution
A hearing test system that includes a sound generating unit, user interface, and control unit to determine the credibility of hearing tests by generating testing sounds at different volumes and frequencies, and using blank stimulating sounds to verify reliability, allowing for adjustable hearing function settings based on individual hearing thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional assistive listening devices use fixed hearing curve settings, then the device can be manufactured and distributed easily, but the device cannot adapt to individual hearing impairments and provides suboptimal performance
Solution Approach 1:
The patent performs hearing tests and determines hearing thresholds before the assistive listening device is fully configured for use. By conducting the hearing test in advance and storing the results, the system prepares personalized hearing profiles that will be used to automatically adjust the device settings, eliminating the need for complex real-time adjustments during actual use.
Solution Approach 2:
The system enables users to perform their own hearing tests using the integrated sound generating unit and user interface. The control unit automatically processes the user's responses to determine hearing thresholds and configures the device settings based on the test results, allowing the device to serve itself in the customization process without requiring external audiologist intervention.
2Reliability
If hearing tests are conducted without verification mechanisms, then the testing process is simple and quick, but the credibility and reliability of the hearing test results cannot be ensured
Solution Approach 1:
The patent incorporates a feedback mechanism where the system presents testing sounds to the user and receives the user's responses through the user interface. The control unit processes this feedback to determine whether the user heard the testing sound, using this information to iteratively refine the hearing threshold determination. This feedback loop ensures that the hearing test results are based on actual user responses rather than guesses or errors.
Solution Approach 2:
The system performs verification of hearing test credibility as part of the preliminary hearing test process. By determining both the hearing threshold and the credibility of the test results during the initial setup phase, the system ensures reliable data is available before configuring the assistive listening device, preventing the need for re-testing or adjustments later.
3Adaptability or versatility
If assistive listening devices are designed for specific hearing loss conditions, then the device can be optimized for that condition, but the use range is limited and extensiveness is insufficient
Solution Approach 1:
The patent designs a universal hearing test system and assistive listening device that can accommodate various types and degrees of hearing impairment. The control unit processes hearing test results across multiple frequencies and volumes, determining comprehensive hearing profiles that can be applied to different hearing conditions. This universal approach allows a single device design to serve multiple hearing impairment scenarios without requiring separate optimized devices for each condition.

AI summary
A hearing test system includes a sound generating unit, an user interface, and a control unit. The sound generating unit is configured to generate a first testing sound at a frequency for a subject. The user interface is configured to receive a first feedback of the subject based on the first testing sound. The control unit is configured to determine whether the first feedback is of heard response or an unheard response. When the control unit confirms that the first feedback is of the heard response, the control unit drives the sound generating unit to generate a second testing sound based on a lower testing limit at the frequency, in which a volume of the second testing sound is less than or substantially equal to a volume of the first testing sound.
