Hearing-Test Equalizer Adjustment for High-Frequency Hearing Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing equalizers do not effectively adjust sound output to accommodate the impaired hearing of elderly or hearing-impaired individuals, particularly in higher frequency ranges, limiting their ability to hear sounds clearly.
Innovation Solution
An electronic device with an equalizer adjustment system that includes a testing module to determine minimum gain values for different frequencies, a parameter calculation module to generate correction parameters, and a parameter setting module to adjust equalizer settings based on these values, ensuring that sound output is optimized for the user's hearing condition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional equalizers are used with fixed gain values, then the device complexity is low and ease of operation is good, but the adaptability to different hearing conditions is poor
Solution Approach 1:
The system performs hearing tests and automatically generates equalizer settings without requiring manual user input or professional audiologist intervention. The device serves itself by conducting the hearing evaluation and configuring the optimal equalizer parameters based on the measured hearing thresholds.
Solution Approach 2:
The equalizer gain values are dynamically adjusted based on the measured hearing thresholds. The system calculates correction parameters by comparing minimum audible gain values across different frequencies and applies these corrections to optimize sound output for the user's specific hearing condition.
2Measurement precision
If manual equalizer adjustment is used, then the ease of operation is good, but the measurement precision of hearing ability is insufficient
Solution Approach 1:
The system presents test tones at different frequencies and gain levels, and uses the user's responses to determine minimum audible thresholds. This feedback loop allows the system to precisely map the user's hearing sensitivity across the frequency spectrum, achieving accurate measurement without requiring manual adjustment by the user.
Solution Approach 2:
The system performs a hearing test before equalizer adjustment to establish baseline hearing thresholds. This preliminary measurement enables the subsequent equalizer configuration to be precisely tailored to the user's actual hearing capabilities rather than relying on generic presets or manual estimation.
3Loss of information
If equalizer settings are not customized, then the device complexity is low, but the loss of information in high-frequency sounds for hearing-impaired users is significant
Solution Approach 1:
The equalizer adjustment is applied selectively to specific frequency ranges where the user has hearing deficiencies. Rather than uniformly boosting all frequencies, the system identifies problematic frequency bands from the hearing test and applies targeted gain corrections only where needed, preserving high-frequency information that would otherwise be lost.

AI summary
Disclosed is an electronic device comprising an equalizer and an equalizer adjustment system. The equalizer adjustment system for adjusting the settings of the equalizer comprises a testing module, a parameter calculation module and a parameter setting module. The testing module is used to provide a hearing test procedure for assessing a user's physiological condition of hearing so that after the user completes the hearing test procedure, the parameter calculation module and the parameter setting module can adjust the settings of the equalizer according to the user's physiological condition of hearing.
