Spatial Audio Field Rotation to Reduce Cooling Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing popularity of spatial audio in multimedia content leads to higher computational demands, resulting in cooling system noise that disrupts user experience, as cooling fans generate distracting background noise, especially when users are close to audio source devices.
Innovation Solution
An apparatus that receives user position information within a spatial audio field, determines audio volume levels, and assesses background noise to generate control information for adjusting the audio source device, such as modifying cooling fan speeds or rotating the spatial audio field to minimize noise interference.

Engineering Contradiction Analysis
1Power
If the audio source device increases computational power to process spatial audio content, then the quality of spatial audio processing is improved, but cooling system noise increases and disrupts user experience
Solution Approach 1:
The patent applies dynamics by making the spatial audio field rotatable and the audio content repositionable in real-time. The system dynamically adjusts the spatial audio field orientation based on user position detection, allowing the audio content to be redirected away from the cooling system noise source, thereby reducing noise interference while maintaining computational performance
Solution Approach 2:
The patent converts the harmful cooling system noise into a beneficial situation by using the noise as a reference point for spatial audio field rotation. The system detects user position relative to the noise source and rotates the spatial audio field to position high-quality audio content away from the noise, transforming the noisy environment into an optimized listening experience
2Productivity
If the audio source device generates more background noise from cooling systems, then the computational performance is improved, but the user experience deteriorates due to distracting noise
Solution Approach 1:
The patent implements feedback by continuously detecting user position within the spatial audio field and using this information to adjust the audio field orientation. The system monitors user movement and rotates the spatial audio field in real-time to maintain optimal positioning, creating a closed-loop control system that enhances user experience based on actual user location
Solution Approach 2:
The patent applies parameter changes by modifying the spatial audio field orientation parameters based on user position. The system changes the angular parameters of the spatial audio field to redirect audio content away from noise sources, dynamically adjusting spatial parameters to optimize the listening experience while maintaining high computational performance
