Adaptive Noise Control via Network Connection Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to effectively suppress noise in audio signals during calls, especially when the noise source changes, as they rely on fixed noise suppression parameters set for specific sound sources, failing to adapt to new noise sources.
Innovation Solution
An electronic device acquires network connection information of an external device during a call and uses this information to identify and apply appropriate noise control parameters for noise suppression, allowing adaptive noise management regardless of the network connection type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed noise suppression parameters are used, then noise suppression works well for specific sound sources, but it fails to suppress other noise sources when they occur
Solution Approach 1:
The patent implements dynamic noise suppression parameters that automatically adjust based on detected noise characteristics. The system transitions from fixed parameters to dynamic parameters that adapt in real-time to different noise sources, allowing the noise suppressor to maintain effectiveness across various noise conditions without manual intervention.
Solution Approach 2:
The system changes noise suppression parameters based on detected noise characteristics. By monitoring the audio signal and identifying noise types, the system automatically modifies suppression parameters to match the current noise conditions, thereby resolving the contradiction between reliability for specific sources and adaptability to new sources.
2Object-affected harmful factors
If noise suppression is always applied, then noise is reduced, but voice quality may deteriorate due to over-suppression
Solution Approach 1:
The patent applies noise suppression selectively rather than continuously. The system detects noise characteristics and applies suppression only when and where needed, using partial action to target specific noise components while preserving voice quality. This avoids over-suppression by activating noise reduction only when noise is actually present and matches the suppression profile.
Solution Approach 2:
The system applies different suppression levels to different frequency bands and time periods based on local noise characteristics. By analyzing the audio signal and applying targeted suppression only to noise-affected portions, the system maintains voice quality while effectively reducing noise, rather than applying uniform suppression across the entire signal.
3Adaptability or versatility
If adaptive noise suppression is implemented, then various noise sources can be suppressed, but device complexity increases
Solution Approach 1:
The patent implements a self-service noise suppression system that automatically detects noise characteristics and adjusts parameters without external control. The system monitors its own performance and autonomously adapts to different noise conditions, reducing the need for complex external control mechanisms while maintaining high adaptability across various noise sources.
Solution Approach 2:
The system uses feedback from noise detection to automatically adjust suppression parameters. By continuously monitoring the audio signal and feeding this information back to the parameter adjustment mechanism, the system achieves adaptive noise suppression with relatively simple architecture, as the feedback loop automatically handles the complexity of adapting to different noise sources.
