Dynamic Audio Calibration for Mobile Listeners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio systems are calibrated based on fixed environments and do not account for changing locations of speakers and listeners, nor individual preferences, leading to inconsistent audio experiences.
Innovation Solution
A dynamic audio system that tracks individuals and calibrates speaker output in real-time using acoustic models and profile information, adjusting audio signals based on the location of mobile devices and speakers to provide a uniform listening experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If speakers are calibrated based on a fixed environment with known locations, then the calibration process is simple and quick, but the audio experience becomes inconsistent when speakers or listeners move
Solution Approach 1:
The patent implements dynamic audio calibration by continuously tracking the locations of speakers and listeners using mobile devices with GPS or other location services. The system updates the acoustic model in real-time as entities move, transforming the static calibration approach into a dynamic one that adapts to changing environments while maintaining consistent audio quality.
Solution Approach 2:
The system employs feedback mechanisms where the mobile device communicates location information back to the audio system, which then adjusts speaker output accordingly. This closed-loop feedback ensures that the audio calibration remains accurate even as speakers or listeners move to different positions in the environment.
2Device complexity
If the system uses fixed calibration data, then the system complexity is low, but it cannot account for individual listener preferences
Solution Approach 1:
The patent applies local quality by creating personalized audio profiles for individual listeners based on their location and preferences. Each listener can have customized audio settings that are automatically applied when they are detected in the environment, allowing the system to provide tailored audio experiences without requiring complete reconfiguration for each user.
Solution Approach 2:
The mobile device serves multiple functions: it acts as a location tracker, a preference profile storage device, and a communication bridge between the listener and the audio system. This multi-functionality reduces overall system complexity by consolidating multiple components into a single universal device.
3Reliability
If the system dynamically tracks and adjusts audio in real-time, then the audio experience is consistent and personalized, but the computational requirements and system complexity increase
Solution Approach 1:
The mobile device acts as an intermediary that handles the computationally intensive tasks of location tracking and preference management. By offloading these processing requirements to the mobile device rather than the audio system itself, the patent reduces the processing complexity burden on the audio system while maintaining real-time dynamic adjustment capabilities.

AI summary
An audio adjustment and profile system is provided that can track individuals and speaker locations in an area to dynamically calibrate speakers to provide a uniform listening experience. The system can generate an acoustic model of a room and further calibrate speakers using the acoustic model. The audio adjustment and profile system can also use profile information associated with the listener to customize the listening experience based on the preference information in the profile information. The preference information can comprise mood preferences that emphasize certain frequencies and tones while limiting others.
