Headset Volume Control for External Voice Detection and Hearing Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing headsets with automatic volume adjustment technologies struggle to effectively balance internal audio and external noise, leading to user inconvenience and potential hearing damage due to inconsistent volume levels when interacting with others or in noisy environments.
Innovation Solution
A control module and method for automatically adjusting headset volume by sampling external real-time sound signals, analyzing frequency features, and adjusting volume based on external voice and noise signals, using a digital filter and inherent acoustic characteristics to differentiate and respond to external voices and noise, with the option to manually override through user actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the headset maintains isolation and plays music at high volume, then the user's hearing effect is improved, but the user cannot hear external voices and may suffer hearing loss
Solution Approach 1:
The system continuously monitors external noise levels through the microphone and uses this feedback to dynamically adjust the music volume. When external noise exceeds a threshold, the system automatically reduces music volume to prevent hearing loss while maintaining communication capability.
Solution Approach 2:
The headset transitions from static volume control to dynamic volume adjustment based on real-time environmental conditions. The volume is not fixed but continuously adapted according to external noise levels, allowing the system to balance music enjoyment with hearing protection.
2Ease of operation
If the headset provides noise isolation, then the user's music listening experience is improved, but the user cannot hear external voices
Solution Approach 1:
The system uses the microphone to continuously detect external voices and uses this information as feedback to adjust the audio output. When voices are detected, the system automatically reduces music volume or pauses playback, allowing the user to hear external conversations without removing the headset.
Solution Approach 2:
The headset autonomously monitors its own environment and automatically adjusts its behavior without user intervention. The system serves itself by detecting external noise levels and autonomously adjusting volume, eliminating the need for users to manually adjust settings or remove the headset.
3Ease of operation
If the user increases speaking voice to be heard, then communication is improved, but the user's hearing is exposed to harmful noise levels
Solution Approach 1:
The system detects external voice signals through the microphone and uses this feedback to automatically reduce music volume when communication is needed. This eliminates the need for users to speak louder, as the system automatically creates acoustic space for external voices while protecting hearing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures users can communicate effectively without removing the headset and minimizes hearing damage by dynamically adjusting volume based on external noise levels, maintaining optimal listening conditions while preventing prolonged exposure to loud music.
Implementation Method 1
an audio signal sampling and MIC module for sampling an external real-time sound signal and converting the real-time sound signal into an electrical signal
Implementation Method 2
an acoustic feature analyzing module electrically connected to the audio signal sampling and MIC module and the headset acoustic characteristic recording module for removing an audio signal played by the headset from the real-time sound signal based on the system inherent acoustic characteristic of the headset to obtain a pure external noise and voice signal outside the headset

AI summary
The present invention discloses a headset, a control module and method for automatic adjustment of a volume of the headset, and a storage medium. The control module comprises an audio signal sampling and MIC module, a headset acoustic characteristic recording module, an acoustic feature analyzing module, an external sound signal analyzing module and a volume adjustment module. The volume adjustment module may determine a person speaking and automatically control the headset to lower the volume or mute when the strength of the external voice signal is larger than a preset threshold value. The control module of the present invention may automatically decrease the volume of the headset by identifying a voice signal from the external environment or the user, such that the user may make normal communication with other person without taking off the headset and the hearing of the user may not be damaged.
