Autonomous Audio Playback Control for Changing Ambient Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial sectors face challenges in maintaining optimal sound volume levels due to varying customer numbers and background noise, which often result in poor audio solutions when staff are unable to monitor and adjust settings effectively.
Innovation Solution
The Autonomous Volume Adjustment (AVA) system, an always-on algorithm that monitors noise levels and adjusts playback settings, including volume, treble, bass, and frequency, in real-time using multiple microphones to match listening conditions, and learns from patterns to optimize audio experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If staff manually monitor and adjust sound volume levels, then audio performance can be optimized, but staff attention is diverted from customer service
Solution Approach 1:
The audio system automatically monitors ambient noise levels and adjusts playback volume without human intervention. The processor continuously receives noise level data from microphones and autonomously modifies speaker output to maintain optimal audio performance while freeing staff to focus entirely on customer service
Solution Approach 2:
The system implements a closed-loop feedback mechanism where microphones continuously measure ambient noise levels, the processor analyzes this data, and automatically adjusts speaker volume in real-time. This continuous monitoring and adjustment cycle ensures optimal audio performance adapts dynamically to changing environmental conditions
2Reliability
If sound volume is increased to accommodate high background noise, then audio remains audible, but customer experience deteriorates when customer numbers are low
Solution Approach 1:
The system dynamically adjusts sound volume based on real-time ambient noise measurements rather than maintaining a fixed volume level. As customer numbers and background noise fluctuate, the processor continuously modifies speaker output to keep audio audible during busy periods while reducing volume during quieter times to enhance customer experience
Solution Approach 2:
The system changes the volume parameter of audio playback based on measured ambient noise levels. The processor analyzes noise level data and automatically adjusts the playback volume parameter to maintain audio audibility when noise is high while preventing excessive volume when noise is low, thus avoiding negative impact on customer experience
3Reliability
If audio settings are adjusted frequently to match changing conditions, then audio quality is maintained, but system complexity increases
Solution Approach 1:
The processor performs multiple functions: it monitors ambient noise levels through microphones, analyzes the noise data, determines appropriate volume adjustments, and controls speaker output. This multi-functional approach maintains audio quality through automatic adaptation while avoiding the need for separate manual control systems
Solution Approach 2:
The system replaces manual mechanical adjustment of volume controls with an automated electronic control system. The processor electronically adjusts speaker volume based on sensor data, eliminating the need for physical intervention and reducing operational complexity while maintaining consistent audio quality

AI summary
A computer implemented method for managing a sound emitting device comprising: receiving data associated with operation of the sound emitting device at a predetermined location; processing said data to determine an operating characteristic of that device for that location; comparing the operating characteristic with a predetermined mathematical relationship to determine whether a difference exists; and identifying an input adjustment to correct the difference wherein the input adjustment optionally is within a predetermined range and optionally does not exceed a predetermined maximum increment; wherein the predetermined mathematical relationship is between an input variable and an output variable in respect of the sound emitting device.
