Localized Audio Leveling for Multi-User Volume Personalization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of multimedia systems often disagree on the appropriate audio volume, leading to a less than satisfactory experience due to the inability to personalize sound levels according to individual preferences.
Innovation Solution
A method and system that determine the location and relative audio volume preference of each user, using techniques such as microphone triangulation, RF signals, and graphical user interfaces, to output localized audio volumes, adjusting and storing these preferences for future sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single audio volume level is output for all users, then the system is simple to operate, but users with different volume preferences cannot personalize their listening experience
Solution Approach 1:
The patent applies local quality by creating different audio volume zones in different physical locations around the display device. Each zone is associated with a specific user's volume preference, allowing localized audio personalization without requiring complex individual device control for each user. The system determines user location and outputs audio at the appropriate volume level for that specific location.
2Adaptability or versatility
If the system determines location and volume preferences for each user, then audio personalization is achieved, but the system requires complex processing and multiple components
Solution Approach 1:
The system applies self-service by automatically determining user location using existing microphones and RF signals, and automatically applying the appropriate volume preference without requiring manual user input or complex configuration. The system serves itself by utilizing already-present hardware components (microphones, RF transmitters/receivers) for location determination rather than requiring additional specialized sensors.
3Measurement precision
If differential level and delay compensation filtering is applied to produce psychoacoustic perceptions, then localized audio volumes are achieved, but the processing complexity increases
Solution Approach 1:
The patent replaces mechanical audio adjustment methods with digital signal processing. Instead of using physical volume controls or mechanical attenuators for each user, the system uses differential level and delay compensation filtering implemented through a signal processor. This substitution allows for precise audio localization and personalization through software-based processing rather than hardware adjustments.

AI summary
Techniques for personalizing audio levels, in accordance with embodiments of the present technology, provide different audio volumes to different locations in a room allowing for two of more users to enjoy the same audio content at different volumes. Differential level and delay compensation filtering based on a position of each of a plurality of speakers, the location of each user and the preferred relative audio volume of each user are utilized to produce different effective audio levels in localized regions of a room.
