Solution Overview
Problem
Modern hearing aids with complex signal processing systems pose challenges for fitters during the fitting procedure, as these systems adapt their operation over time, making it difficult to verify their current state and adjust settings effectively.
Innovation Solution
A programming equipment and method that reads data from the hearing aid, derives parameters representing the current state of signal processing systems, calculates models, and displays a graphical representation of the operation, allowing fitters to visualize and understand the current state of directional, feedback cancellation, and transposing systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex signal processing systems are used in hearing aids to improve performance, then the hearing aid's adaptability and functionality are improved, but the difficulty of detecting and measuring the current state of operation increases
Solution Approach 1:
The patent introduces an intermediary system consisting of a transmitter in the hearing aid and a display device in the fitting system. This intermediary translates the internal state of complex signal processing systems into visual representations that fitters can easily interpret, thereby resolving the contradiction between system complexity and measurability.
Solution Approach 2:
The patent implements a feedback mechanism where the current state of signal processing systems is continuously monitored, transmitted to the fitting system, and displayed to the fitter. This real-time feedback loop allows fitters to verify and adjust settings effectively, overcoming the difficulty of measuring complex system states.
2Adaptability or versatility
If signal processing systems adapt their operation over time to improve user experience, then the hearing aid's versatility is improved, but the ease of operation during fitting procedure deteriorates
Solution Approach 1:
The fitting system receives real-time data from the hearing aid about the current state of adaptive signal processing systems and displays this information to the fitter. This feedback enables the fitter to understand and control the adaptive behavior, maintaining ease of operation despite the system's complexity.
Solution Approach 2:
An intermediary communication channel between the hearing aid and fitting system translates adaptive system states into comprehensible visual formats, allowing fitters to easily monitor and adjust settings even as systems adapt over time.
3Measurement precision
If real-time data transmission from hearing aid to fitting system is implemented to improve fitting accuracy, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The system transmits only essential state information from the hearing aid to the fitting system, rather than all possible data. This partial transmission approach maintains measurement precision for critical parameters while minimizing energy consumption.
Solution Approach 2:
The patent extracts and transmits only the most relevant state information from the complex signal processing systems to the fitting system. This selective extraction achieves sufficient measurement precision for fitting purposes while reducing the energy burden of data transmission.
