Portable Terminal Volume Adjustment via Noise Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals face challenges in maintaining call quality due to varying background noise levels, which users must manually adjust, leading to inconvenience and increased risk of accidents, especially when driving or in noisy environments.
Innovation Solution
An apparatus and method for automatically adjusting the volume in portable terminals based on collected noise judgment information, including background noise, vehicle state, weather, and movement speed, using a controller, information collection unit, and volume adjustment unit to enhance call quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user manually adjusts the volume to improve call quality in noisy environments, then the call quality is improved, but the ease of operation deteriorates due to the inconvenience of manual adjustment
Solution Approach 1:
The system automatically detects background noise levels and adjusts the volume without requiring user intervention. The noise detection unit continuously monitors the environment and the volume adjustment unit autonomously modifies the audio output based on detected noise conditions, allowing the system to serve itself rather than requiring manual user control.
Solution Approach 2:
The system implements a feedback loop where the noise detection unit continuously monitors background noise levels and provides this information to the volume adjustment unit, which then adjusts the volume accordingly. This closed-loop control ensures that the volume adapts dynamically to changing environmental conditions while maintaining optimal call quality.
2Reliability
If the user increases the volume manually to compensate for background noise, then the call quality is improved, but the safety deteriorates due to the risk of traffic accidents when driving
Solution Approach 1:
The system automatically detects background noise levels and adjusts the volume without requiring user intervention. The noise detection unit continuously monitors the environment and the volume adjustment unit autonomously modifies the audio output based on detected noise conditions, allowing the system to serve itself rather than requiring manual user control.
Solution Approach 2:
The system proactively adjusts the volume in advance based on detected noise conditions before the user needs to manually intervene. By continuously monitoring the environment and anticipating noise-related call quality issues, the system performs the volume adjustment beforehand, preventing the need for distracting manual operations during critical moments.
3Ease of operation
If the system automatically adjusts volume based on noise detection, then the ease of operation is improved, but the device complexity increases due to additional components
Solution Approach 1:
The noise detection unit and volume adjustment unit are integrated into the existing portable terminal architecture, allowing these components to serve multiple functions. The noise detection capability can be reused for other audio processing tasks, and the volume adjustment mechanism works across different audio outputs, reducing the need for separate dedicated components for each function.
Solution Approach 2:
The system combines the noise detection and volume adjustment functions into an integrated automated volume control system. Rather than adding completely separate components, the invention merges these functions into a coordinated subsystem that works together with the existing audio processing architecture, minimizing the increase in overall device complexity.
