Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional fitting process for hearing devices is time-consuming and requires multiple visits to a hearing professional, with users often needing to adjust audio processing parameters iteratively, which can be inconvenient and inefficient.
Innovation Solution
A fitting arrangement that uses a computer system and software to play an audio sequence comprising multiple real-life sound objects simultaneously with synchronized visualization, allowing users to select and adjust audio processing parameters based on their preferences, reducing the need for extensive professional intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional iterative fitting method with multiple professional visits is used, then fitting accuracy can be improved through fine-tuning, but time consumption and resource requirements increase significantly
Solution Approach 1:
The system performs preliminary fitting actions by automatically generating test tones and collecting user responses through the mobile device interface, preparing the fitting data before professional review. This preliminary automated fitting reduces the need for multiple iterative visits while maintaining accuracy through pre-collected response data.
Solution Approach 2:
The hearing device and mobile application enable users to perform self-fitting by automatically generating test tones, collecting user responses, and adjusting parameters without requiring constant professional intervention. The system serves itself by automating the test tone generation and response collection process, reducing time consumption while maintaining fitting accuracy.
2Loss of time
If user performs self-fitting with automated test tones, then time consumption is reduced, but fitting accuracy may deteriorate due to lack of professional guidance
Solution Approach 1:
The mobile application serves as an intermediary between the hearing device and the user, providing professional-grade fitting guidance through the application interface while enabling self-fitting. The intermediary software translates complex fitting procedures into user-friendly interactions, maintaining accuracy while reducing time consumption through automated processes.
3Productivity
If multiple audio processing parameters are adjusted simultaneously, then fitting efficiency is improved, but device complexity increases
Solution Approach 1:
The mobile application provides a universal interface that handles multiple audio processing parameters through unified controls and presentations. The software consolidates complex parameter adjustments into user-friendly presentations, enabling efficient simultaneous adjustment of multiple parameters while masking the underlying complexity through multi-functional interface design.
4Adaptability or versatility
If real-life sound scenarios are used for fitting, then adaptability to everyday situations is improved, but test complexity and resource requirements increase
Solution Approach 1:
The system uses synthesized test tones that copy and simulate real-life sound scenarios rather than requiring actual complex environmental recordings. By creating simplified audio presentations that replicate essential characteristics of real-life sounds, the system achieves good adaptability to everyday situations while reducing test complexity and resource requirements compared to using actual environmental recordings.

AI summary
The method for adjusting a hearing system (2) to the preferences of a user (3) of the hearing system comprises a) playing an audio sequence to said user (3); wherein the audio sequence comprises a first sound object representative of a first real-life sound source and a second sound object representative of a second real-life sound source; b) receiving an input (R) in response to step a); c) adjusting at least one audio processing parameter (P) of said hearing system (2) in dependence of said input (R). Preferably, the method further comprises d) providing the user (3) synchronously with step a) with a visualization of a scene to which said audio sequence belongs; and providing a user input (U) which is indicative of a sound source or of a sound object or of an instant in or a portion of the audio sequence; and automatically selecting an audio processing parameter (P) of the hearing system (2) in dependence of the user input (U) and offering the selected audio processing parameter (P) for adjusting.
