Hearing Instrument EEG Relaxation Mode Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hearing instruments do not adapt settings based on the user's mental state, leading to cumbersome adjustments and potential missed important sounds during relaxation or when misplaced.
Innovation Solution
A system comprising EEG electrodes and a controller that detects brain wave signals to automatically switch the hearing instrument between relaxation and active modes, adjusting settings such as gain and filtering based on the user's mental state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user manually adjusts hearing instrument settings for different mental states, then the hearing instrument can provide appropriate sound amplification for different conditions, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The hearing instrument automatically detects the user's mental state through EEG electrodes and adjusts settings without user intervention. The system monitors brain wave signals and autonomously switches between relaxation and active modes, eliminating the need for manual configuration changes while adapting to different mental states
Solution Approach 2:
The system continuously monitors EEG signals from the user's scalp and uses this feedback to dynamically adjust hearing instrument settings. The detector analyzes brain wave patterns in real-time and provides feedback to the controller, which automatically modifies amplification and filtering parameters according to the detected mental state
2Use of energy by moving object
If the hearing instrument is switched off during relaxation, then power consumption is reduced, but important sounds such as telephone rings or doorbells may be missed
Solution Approach 1:
The hearing instrument dynamically adjusts its operational state based on the user's mental state rather than being statically on or off. During relaxation, the system transitions to a low-power mode that maintains minimal monitoring capability, automatically activating full functionality when alertness is detected, thus balancing energy savings with reliability
Solution Approach 2:
The system prepares for important sounds by maintaining EEG monitoring even in relaxation mode, detecting changes in brain wave patterns that indicate the user has noticed or is about to notice an important sound, and pre-activating full hearing instrument functionality before the sound becomes critical
3Extent of automation
If EEG electrodes are integrated into the hearing instrument, then mental state detection is enabled, but the device complexity increases
Solution Approach 1:
The hearing instrument housing serves multiple functions: it provides structural support for hearing aid components and simultaneously acts as an electrode carrier for EEG measurement. The housing material itself is configured to conduct electrical signals, eliminating the need for separate electrode structures and reducing overall device complexity while enabling mental state detection

Data Source
AI summary
A system for operating a hearing instrument is disclosed. The system comprises one or more electrodes for measuring the brain wave signals of a user wearing a hearing instrument. The electrodes are placed on the scalp of the user. Based on the measured brain wave signals, a detecting unit is configured to detect a relaxation state of the hearing instrument. A controller sets the hearing instrument to a relaxation mode setting in response to the detection of the relaxation state of the user.
