Hearing Aid Automatic Sound Classification and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing aids require frequent manual adjustments and resets by an acoustician to adapt to changing acoustic environments, making individual sound settings inconvenient and time-consuming.
Innovation Solution
A hearing aid with a classification device that automatically classifies the hearing situation and a setting device that uses a remote control to set sound settings, storing these settings with their classification for seamless adaptation to changing environments, allowing for automatic recall and cross-fading between settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of sound settings is performed, then sound quality can be customized for different hearing situations, but frequent resets and readjustment by an acoustician are required
Solution Approach 1:
The hearing aid automatically detects hearing situations using a classification device and adjusts sound settings without requiring manual intervention by an acoustician. The system stores multiple sound settings and automatically selects and applies the appropriate setting based on the detected hearing situation, enabling the device to serve itself rather than requiring external adjustment.
Solution Approach 2:
The hearing aid transitions from static, fixed sound settings to dynamic, automatically adjustable settings. The classification device continuously monitors the hearing situation and dynamically changes sound parameters in real-time based on environmental conditions, allowing the system to adapt flexibly to varying acoustic requirements.
2Ease of manufacture
If fixed sound settings are established during adaptation session, then initial sound configuration is provided, but constant resetting and readjustment is necessary to match changing acoustic requirements
Solution Approach 1:
Multiple sound settings are pre-configured during the adaptation session with an acoustician and stored in the hearing aid's memory. These preliminary settings cover various hearing situations, and the system automatically selects the appropriate pre-configured setting based on real-time classification of the acoustic environment, eliminating the need for constant manual resetting.
3Adaptability or versatility
If test parameter sets are provided for each hearing situation, then wearer can determine best settings, but interactive adapting procedures require various settings to be assessed
Solution Approach 1:
The hearing aid automatically evaluates and selects the best sound setting based on classification of the hearing situation, eliminating the need for the wearer to manually assess multiple test parameter sets. The system performs the adaptation process autonomously by detecting the acoustic environment and automatically applying the most appropriate pre-configured sound setting.

AI summary
The adaptation of a hearing aid to the wearer is made more convenient according to a hearing aid and method of use. A hearing situation is classified according to a hearing situation at any one time, the sound of the hearing aid is stored, and subsequently the sound setting with the assigned classification is stored. In this case, the sound setting is automatically stored with the associated classification after each adjustment.
