Personalized Equalizer Tuning Using Hearing Test Frequency Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current equalizers lack the ability to adjust sound gain values based on individual users' unique hearing abilities, leading to suboptimal auditory experiences.
Innovation Solution
An electronic device with a sound processing system that includes a hearing test module, age determination module, and equalizer adjustment module, which measures hearing loss and adjusts gain values at different frequencies using a stored age gain value list to compensate for hearing impairments, ensuring personalized sound adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the equalizer uses fixed gain value settings or built-in modes, then the operation is simple and device complexity is low, but the adaptability to different users' hearing abilities is poor
Solution Approach 1:
The system performs a hearing test before equalizer adjustment to obtain hearing loss data in advance. This preliminary measurement allows the system to store correction parameters for different frequency bands based on the user's actual hearing condition, enabling personalized equalizer settings without requiring complex real-time analysis during music playback.
Solution Approach 2:
The system changes the gain values of different frequency bands in the equalizer based on the measured hearing loss parameters. By adjusting the amplification levels of specific frequency ranges according to the user's hearing deficiencies, the system adapts the audio output to match individual hearing characteristics while maintaining a relatively simple overall device architecture.
2Measurement precision
If the equalizer adjusts gain values manually or uses built-in modes, then the ease of operation is high, but the measurement precision of hearing loss is insufficient
Solution Approach 1:
The system performs self-diagnosis by automatically conducting a hearing test and generating correction parameters without requiring professional equipment or expert operation. The user simply interacts with the built-in hearing test module, and the system automatically processes the results to configure the equalizer settings, achieving precise measurement while maintaining ease of use.
Solution Approach 2:
The system uses feedback from the hearing test results to automatically adjust the equalizer gain values. The hearing loss measurement data feeds into the correction parameter calculation, which then feeds back to the equalizer settings, creating a closed-loop system that continuously optimizes audio output based on the user's actual hearing condition.
