Hearing Device Parameter Setting via Transformation Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in efficiently setting parameters for a new hearing device to replicate the sound and transmission characteristics of an old one, especially when the complete characteristic of the old device is unknown, making it difficult for hearing-impaired individuals to adapt to new devices due to technical advancements and changes in hearing ability, and requiring significant effort for manual adjustments.
Innovation Solution
A method involving the creation of a transformation database that determines and stores parameter settings for various hearing devices to achieve identical or similar transmission characteristics, allowing for automated or semi-automated parameter adjustments based on discrete steps and modeling techniques, enabling a first-fit setting that closely mimics the old device's characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual parameter settings are performed by a hearing device acoustician to match the old device's characteristics, then the sound perception can be maintained, but the effort and time required become extremely high
Solution Approach 1:
The patent pre-determines and stores optimal parameter settings in a database before actual device replacement occurs. During replacement, the system automatically retrieves and applies these pre-calculated settings, eliminating the need for time-consuming manual adjustments while maintaining accurate sound perception matching.
Solution Approach 2:
The patent creates a digital model (copy) of the old hearing device's characteristics and uses this model to automatically determine parameters for the new device. This copying approach allows rapid reproduction of the original sound characteristics without manual measurement and adjustment.
2Measurement precision
If complete acoustic analysis of the old hearing device is performed to determine all transmission characteristics, then accurate parameter setting is achieved, but the complexity and cost of the procedure increases significantly
Solution Approach 1:
The patent extracts only the essential characteristic parameters needed for device replacement from the old hearing device, rather than performing a complete comprehensive analysis. This selective extraction maintains sufficient accuracy for parameter matching while significantly reducing procedural complexity and cost.
Solution Approach 2:
The patent transforms the complex acoustic characteristic data into a simplified parameter set that can be stored in a database and used for automatic setting. By changing the representation form from complete acoustic profiles to key parameters, the system reduces complexity while preserving essential information.
3Adaptability or versatility
If hearing devices are exchanged frequently to provide access to new technical functions, then users benefit from technical advancements, but users experience difficulty adapting to new sound characteristics
Solution Approach 1:
The patent creates a digital replica of the user's personalized sound characteristics from their old device and applies this copy to the new device. This allows users to access new technical functions while maintaining their familiar and adapted sound profile, eliminating the adaptation difficulty.
Solution Approach 2:
The patent pre-adapts the new hearing device to match the user's accustomed sound characteristics before the user even receives it. By performing the adaptation in advance through automatic parameter setting, the system eliminates the adjustment period users would otherwise need to adapt to new sound characteristics.
Data Source
AI summary
A method and apparatus for setting a characteristic of a source hearing device on target hearing device are provided. A transformation database is created. A source hearing device including the setting of the source hearing device are identified, the characteristic of setting is to be set on the target hearing device. The setting which, according to the transformation database on the target hearing device, results in the characteristic corresponding to the characteristic of the identified source hearing device is recalled. The target hearing device is set using the recalled setting. Settings are stored in the transformation database during their creation, which have to be set to hearing devices of different types to be set in order to grant these hearing devices the characteristic of other identified hearing with identified settings.
