Hearing Threshold Estimation for Faster Hearing Aid Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hearing aid devices require a significant number of user operations during hearing tests, leading to a substantial operation burden on users, especially when testing multiple frequencies.
Innovation Solution
An information processing apparatus that estimates initial values for untested frequencies based on first test values and user features, reducing the need for extensive user interaction by using an application to set amplification factors in hearing aid devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hearing tests are conducted for all frequencies to ensure accurate hearing aid settings, then measurement precision is improved, but operation burden increases
Solution Approach 1:
The system performs preliminary hearing tests at a subset of frequencies (e.g., 500 Hz, 2000 Hz, 4000 Hz) to obtain baseline hearing thresholds. These preliminary results are then used to estimate thresholds at other frequencies, avoiding the need for users to complete time-consuming tests at all frequencies while still achieving comprehensive hearing aid configuration
Solution Approach 2:
The system creates estimated hearing threshold values for untested frequencies by copying and interpolating from tested frequency points. Mathematical models estimate the hearing thresholds at intermediate frequencies based on the pattern observed at tested frequencies, effectively creating virtual test data that reduces user burden while maintaining reasonable accuracy
2Measurement precision
If hearing tests are conducted for multiple frequencies to improve setting accuracy, then measurement precision is improved, but time consumption increases
Solution Approach 1:
The system conducts preliminary tests at strategically selected frequency points and uses these results to preliminarily configure the hearing aid. This preliminary configuration can be quickly adjusted later if needed, but often provides sufficient accuracy without requiring exhaustive testing at all frequencies, thereby reducing total time investment
Solution Approach 2:
The system performs partial testing at a representative subset of frequencies rather than exhaustive testing at all frequencies. By testing at key frequency points and using interpolation for the rest, the system achieves adequate hearing aid configuration with significantly reduced testing time, accepting that some frequencies are estimated rather than directly measured
