Hearing Aid Fall Risk Prediction via Motion Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of an easy-to-use, objective, and reliable diagnostic/monitoring system for autonomic nervous system (ANS) disorders that can be self-administered, particularly for individuals with hearing loss, and existing fall risk assessment methods have poor diagnostic accuracy and require specialized settings.
Innovation Solution
A hearing aid system equipped with a motion sensor to detect and analyze user movements, predicting fall risk and generating warnings, while also monitoring ANS disorders, using integrated sensors and potentially additional devices for data analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion sensors and movement analysis are integrated into the hearing aid system, then fall risk detection capability is improved, but device complexity increases
Solution Approach 1:
The hearing aid system is designed to perform multiple functions: hearing assistance and fall risk monitoring. The motion sensor (accelerometer) integrated into the hearing aid serves dual purposes - it can detect movements relevant to fall risk assessment while the same hardware supports the primary hearing function, thereby improving reliability without proportionally increasing complexity
Solution Approach 2:
The patent combines the motion sensing capability with the hearing aid system, merging fall detection functionality into an existing wearable device. This integration approach allows the system to leverage the hearing aid's power supply, data processing, and wireless communication capabilities, reducing the need for separate dedicated fall detection equipment
2Adaptability or versatility
If multiple separate solutions are used for hearing loss and ANS disorders, then treatment comprehensiveness is improved, but ease of operation deteriorates
Solution Approach 1:
The hearing aid system is designed to simultaneously address hearing loss and monitor autonomic nervous system disorders through integrated motion sensing. Users wear a single device that provides both hearing assistance and fall risk monitoring, eliminating the need to manage multiple separate solutions and thereby improving ease of operation while maintaining treatment comprehensiveness
Solution Approach 2:
The patent merges hearing aid functionality with fall risk assessment capabilities into a single integrated system. This combination allows users to receive comprehensive care for multiple conditions (hearing loss and ANS disorders) through one device, simplifying the user experience while maintaining adaptability to various health needs

AI summary
The invention relates to a method (40) for operating a hearing system (2) which comprises a hearing aid (4) with at least one input transducer (12) and an output transducer (20) as well as a motion sensor (24), in which a movement of a user of the hearing system is detected as movement data (26) of the motion sensor (24), wherein a probability for a future falling event of the user of the hearing system is determined based on the detected movement data (26), and wherein a perceptible warning signal is generated if the probability reaches or exceeds a stored threshold value.
