Auditory Profile Sharing for Personalized Audio Beamforming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio devices struggle to optimize the audio experience for individual users due to varying auditory profiles and environmental acoustic characteristics.
Innovation Solution
The system uses hardware processors to access and share individual auditory profiles, including hearing transfer functions, across multiple devices. It determines the user's spatial location using sensor data and generates beamforming data to emit audio via steered arrays, optimizing the audio experience based on the user's hearing profile and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If audio devices use standard audio playback without personalization, then device complexity is reduced, but audio quality and user experience deteriorate due to individual hearing differences
Solution Approach 1:
The patent creates a digital copy of the user's auditory profile (hearing transfer function) that can be stored and applied across multiple devices. This copy enables personalized audio processing without requiring complex hardware modifications to each device, as the profile data can be transmitted and applied software-based adjustments.
Solution Approach 2:
The system modifies audio signal parameters (frequency response, amplitude) based on the user's hearing transfer function. By changing these acoustic parameters dynamically, the system adapts standard audio playback to match individual hearing characteristics, improving audio quality without adding physical complexity.
2Manufacturing precision
If audio devices implement personalized audio processing based on individual hearing profiles, then audio quality improves, but processing time and computational resources increase
Solution Approach 1:
The user's hearing transfer function is measured and stored in advance, creating a ready-to-use auditory profile. This preliminary action eliminates the need for real-time hearing analysis during audio playback, as the profile can be quickly applied to modify audio signals without extensive processing delays.
3Adaptability or versatility
If audio systems use simple omnidirectional sound emission, then device complexity is minimized, but audio experience deteriorates due to lack of spatial targeting and environmental adaptation
Solution Approach 1:
The audio system dynamically adjusts beamforming parameters and spatial sound emission based on the user's location and environmental acoustic characteristics. This dynamic adaptation allows the system to optimize audio delivery in real-time without requiring complex manual configuration, as the system automatically responds to changing spatial and environmental conditions.
4Speed
If auditory profiles are stored locally on each device, then data access speed is improved, but data redundancy and storage requirements increase
Solution Approach 1:
The auditory profile serves multiple functions: it can be stored centrally for efficient management and sharing across devices, while also being cached locally on individual devices for quick access during audio playback. This multi-functional approach eliminates data redundancy by allowing the same profile data to serve multiple devices without requiring identical copies on each device.
