Personalized Music Playback Equalization for User Hearing Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music file reproduction terminals cannot accommodate varying hearing abilities of users, as they use fixed-frequency equalization, which limits their ability to satisfy all users and often compromise portability by enlarging the frequency equalizer.
Innovation Solution
A method and apparatus that measure individual hearing ability characteristics by transmitting a basic audible frequency signal and comparing reflection signals to set optimal equalizer settings for audio output, allowing for personalized music file reproduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a frequency equalizer capable of controlling a plurality of frequency band levels is included in a music file reproduction terminal, then the hearing ability characteristics of users can be satisfied, but the size of the frequency equalizer is enlarged, thereby degrading the portability of the music file reproduction terminal
Solution Approach 1:
The patent replaces the traditional mechanical/electronic frequency equalizer with a software-based equalization algorithm implemented in a processor. The processor applies frequency band adjustments through digital signal processing, eliminating the need for additional hardware equalizer components while maintaining the capability to control multiple frequency band levels according to user hearing characteristics.
2Device complexity
If fixed-frequency equalization is used in music file reproduction terminals, then the device structure remains simple, but the varying hearing ability characteristics of different users cannot be satisfied
Solution Approach 1:
The patent implements dynamic equalization settings that can be adjusted based on individual user hearing characteristics. The system includes functionality to measure and store user-specific hearing ability data, and automatically adjusts frequency band levels accordingly. This transforms the static fixed-frequency equalization into a dynamic system that adapts to different users while maintaining simple device structure through software-based control.
