Age-Adaptive Sound Adjustment for Multi-Listener Audio Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound adjustment systems, like equalizers, are inadequate for accommodating the varying auditory needs of multiple listeners with different age-related hearing abilities, as they typically rely on single-user settings or pre-defined modes, failing to optimize sound for diverse age groups.
Innovation Solution
A sound playing system incorporating a camera module for facial analysis to estimate the age of multiple listeners, a sound input module for obtaining audio, and a sound adjustment module that uses equalizer settings based on the target age to process the sound, ensuring the output is suitable for the eldest or average age group, thereby enhancing listening comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If single-user equalizer settings are used, then the sound can be adjusted according to one user's preferences, but it cannot accommodate the varying auditory needs of multiple listeners with different age-related hearing abilities
Solution Approach 1:
The system automatically detects listener ages through facial recognition and autonomously adjusts equalizer settings without requiring manual user input or complex configuration interfaces, enabling the system to serve multiple users with different hearing needs while maintaining simple operation
Solution Approach 2:
The system dynamically changes equalizer parameters (frequency gain values) based on detected listener age, automatically selecting appropriate audio profiles that compensate for age-related hearing loss across different frequency ranges
2Adaptability or versatility
If pre-defined equalizer modes are provided, then users can quickly adjust multiple frequencies at once, but the sound cannot be optimized for diverse age groups with different hearing capabilities
Solution Approach 1:
The system automatically detects listener ages through facial recognition and autonomously adjusts equalizer settings without requiring manual user input or complex configuration interfaces, enabling the system to serve multiple users with different hearing needs while maintaining simple operation
Solution Approach 2:
The system pre-configures multiple equalizer profiles corresponding to different age groups with optimized frequency adjustments, and automatically selects the appropriate profile based on detected listener age, eliminating the need for manual adjustment while providing age-specific optimization
3Adaptability or versatility
If frequency reduction adjustment is applied for older listeners, then hearing comfort is improved for the target age group, but the sound may not be suitable for younger listeners with different auditory requirements
Solution Approach 1:
The system applies different frequency adjustment strategies tailored to specific age groups, with younger listeners receiving settings optimized for full frequency range and older listeners receiving compensated settings that emphasize higher frequencies where age-related hearing loss typically occurs
Solution Approach 2:
The system dynamically adjusts equalizer settings based on real-time detection of listener age, automatically switching between different frequency compensation profiles to maintain optimal sound quality for the current audience composition

AI summary
A method for adjusting playing sound in a sound playing system is disclosed. The sound playing system includes a camera module, a facial analysis module, a sound inputting module, a sound adjustment module, and a speaker. The method includes: obtaining an image of a face of each one of a plurality of people through the camera module; analyzing the image to estimate the age of each one of the plurality of people through the facial analysis module, and obtaining a target age according to the age of each person; obtaining a playing sound through the sound inputting module; adjusting the playing sound according to the target age through the sound adjustment module to obtain an output sound; and playing the output sound through the speaker.
