Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for generating personalized audio profiles are expensive and not feasible with typical user computing devices, requiring measurements taken in an anechoic chamber.
Innovation Solution
A system that generates a personalized audio profile using data collected by a user with a personal computing device, such as a mobile device, by broadcasting sound and recording both the sound and the position of the listener, allowing for the determination of a personalized impulse response or transfer function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurements are taken in an anechoic chamber using audio equipment, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses visual data (images/videos) of the user's head and ears as a copy or representation of their physical characteristics, rather than requiring direct acoustic measurements. This visual copy is then processed to generate personalized audio profiles, eliminating the need for complex anechoic chamber equipment while maintaining measurement precision.
Solution Approach 2:
The patent replaces the mechanical/acoustic measurement system (anechoic chamber, audio equipment) with a visual imaging system. Instead of using microphones and speakers to measure acoustic responses, the system uses cameras to capture visual data of the user's anatomy, which is then computationally processed to achieve the same personalized audio outcome.
2Measurement precision
If measurements are taken in an anechoic chamber, then personalized audio profile accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The patent enables users to perform the measurement process themselves using their own mobile devices. The system guides users through capturing images of their head and ears, and automatically processes this data to generate personalized audio profiles without requiring professional equipment or facilities. This self-service approach dramatically improves ease of operation while maintaining accuracy.
Solution Approach 2:
The patent utilizes a universal mobile device (smartphone or tablet) that most users already possess, rather than requiring specialized measurement equipment. This multi-functional device serves both as the imaging tool and the processing unit, making the system accessible to anyone with a standard mobile device and eliminating the need for expensive, specialized equipment.
3Ease of operation
If visual data and audio data are recorded using a personal computing device, then ease of operation is improved, but measurement precision may deteriorate
Solution Approach 1:
The patent introduces computational algorithms and processing systems as intermediaries between the simple visual data collection and the final audio profile generation. The visual data captured by the mobile device camera is processed through image analysis algorithms to extract anatomical features, which are then used to generate or select appropriate audio profiles. This intermediary processing step bridges the gap between simple data collection and high-precision outcomes.

AI summary
Disclosed implementations for generating personalized audio. In response to receiving sensor data corresponding with a physical characteristic of a user, a first function is determined based on a similarity between the physical characteristic of the user and a first model and a second function is determined based on a similarity of the physical characteristic between the user and a second model. A modified function, representing an audio response, is generated by combining the first function and the second function. An audio stream is generated based on the modified function.
