Headset Volume Control With Voice Compensation for Sound Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During voice communications using a headset, sound leakage can annoy others and potentially disclose sensitive information, as the voice of the remote party may be audible to those nearby, and existing technologies fail to accurately adjust headset volume to account for the local user's voice in ambient sound.
Innovation Solution
A device with a processor and microphone system that detects ambient sound and compensates for the local user's voice by adjusting the headset volume, using a voice compensator to remove the local user's voice from ambient sound measurements, thereby reducing sound leakage and maintaining or increasing volume when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If headset volume is reduced to minimize sound leakage and protect privacy, then sound leakage is reduced, but communication quality deteriorates
Solution Approach 1:
The system continuously monitors ambient sound levels and dynamically adjusts headset volume in real-time based on the detected environment, creating a closed-loop feedback mechanism that optimizes both privacy protection and communication quality
Solution Approach 2:
The headset volume is transformed from a static setting to a dynamic parameter that automatically adapts to changing ambient conditions, allowing the system to maintain optimal performance across different environments
2Object-generated harmful factors
If ambient sound is used to adjust headset volume, then sound leakage is reduced, but the local user's voice is incorrectly detected as ambient sound causing inaccurate volume adjustment
Solution Approach 1:
The system extracts and removes the local user's voice component from the ambient sound signal, isolating only the relevant environmental sounds for volume adjustment decisions
Solution Approach 2:
A voice compensation mechanism acts as an intermediary between the ambient sound detection and volume adjustment, correcting the detection accuracy by accounting for the user's own voice presence

AI summary
An example device includes a headset interface to connect a headset that includes a speaker and a first microphone, a second microphone to detect ambient sound in an environment of the device, and a processor connected to the headset interface and the second microphone. The processor is to perform a volume adjustment to sound to be outputted at the speaker of the headset based on the ambient sound detected by the second microphone during a call that uses the headset. The processor is further to compensate the volume adjustment for a user's voice detected at the first microphone.
