Headset Sound Signal Processing Based on User Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sound processing methods in headsets fail to effectively filter out ambient sounds that are not relevant to the user's current context, leading to disturbances during activities like calls or music listening, as they do not consider user status information such as location or motion mode.
Innovation Solution
A sound signal processing method and system that uses a terminal and headset to collect and process ambient sounds based on user status information, determining whether to generate a prompt signal or perform noise reduction based on geographical location, motion status, and service priorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the headset outputs all ambient sound signals collected from the external environment, then the user receives complete sound information, but the user experiences unnecessary disturbance and reduced focus during current activities
Solution Approach 1:
The patent applies local quality by differentiating the processing of ambient sound signals based on their characteristics and user context. Instead of uniformly handling all ambient sounds, the system selectively processes different types of sounds (e.g., prompts vs. noise) and outputs them differently based on local quality criteria, thereby reducing unnecessary disturbance while preserving important information.
Solution Approach 2:
The system changes parameters of ambient sound signal processing dynamically based on user status information. By adjusting processing parameters (such as whether to output the signal or apply noise reduction) according to changing user contexts (location, motion mode, service type), the system optimizes the balance between information completeness and disturbance reduction.
2Object-affected harmful factors
If the headset filters out all ambient sound signals, then the user experiences minimal disturbance, but the user loses important safety information and contextual awareness
Solution Approach 1:
The patent extracts and separates ambient sound signals into different categories (e.g., prompt signals vs. noise signals) based on their characteristics. By taking out and processing different types of signals differently, the system can filter out disturbing noise while preserving important safety information and contextual awareness through selective extraction and processing.
Solution Approach 2:
The system introduces an intermediary processing layer that analyzes ambient sound signals against user status information before output. This intermediary mechanism (the processing apparatus) mediates between the raw ambient sound information and the user's needs, selectively transmitting information while filtering disturbances based on contextual criteria.
3Ease of operation
If the system processes all ambient sound signals based on user status information, then the user experience is optimized, but the processing complexity and computational resources increase
Solution Approach 1:
The patent segments the ambient sound signal processing into distinct stages: collection, feature analysis, user status matching, and selective processing. By dividing the complex processing task into manageable segments, the system achieves optimized user experience through structured analysis while managing computational complexity through hierarchical processing stages.
Solution Approach 2:
The system applies partial processing by analyzing only the necessary features of ambient sound signals (such as sound type, source location) rather than performing complete analysis on all signals. This partial action approach optimizes user experience for relevant signals while reducing overall processing complexity by avoiding excessive analysis of irrelevant sounds.

AI summary
The present invention discloses a sound signal processing method, a terminal, and a headset, to prevent a sound in an external environment from causing unnecessary disturbance to a user, thereby improving user experience. The terminal includes: a microphone, configured to collect an ambient sound signal; and a processor, configured to: obtain the sound signal collected by the microphone, and process, based on user status information, the ambient sound signal collected by the microphone, where the user status information includes a geographical location of a user who uses the terminal or a motion status of the user.
