Hearing Test Segmentation with Cognitive Interleaving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing tests using audiometers often become predictable and tedious, leading to decreased accuracy due to the test subject's boredom or distraction, as the timing of test stimuli becomes known and similar tones at various frequencies are repeated.
Innovation Solution
The hearing test is divided into segments based on frequency ranges, with cognitive or awareness-based segments interleaved to maintain subject engagement, and the system repeats segments if the subject appears distracted, using visual, audio, and tactile stimuli to assess attention and adjust the test accordingly, including image processing for proper headset placement and demographic-based scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hearing test segments are repeated to ensure accurate results, then measurement precision is improved, but test duration increases and subject engagement decreases
Solution Approach 1:
The hearing test is divided into multiple segments, each targeting specific frequency ranges. This segmentation allows the system to administer focused test portions rather than requiring complete repetition of entire tests, reducing overall duration while maintaining accuracy through targeted re-testing of specific segments where engagement issues occurred.
Solution Approach 2:
The system implements periodic cognitive or awareness-based segments interspersed within hearing test segments. These periodic interruptions serve to re-engage the subject's attention and prevent boredom, allowing the hearing test to proceed more efficiently with fewer repetitions needed, thus reducing total test duration while maintaining accuracy.
2Reliability
If cognitive or awareness-based segments are interleaved with hearing test segments, then subject engagement is maintained, but device complexity increases
Solution Approach 1:
The hearing test system is designed to perform multiple functions: administering hearing tests, evaluating cognitive/awareness levels, and monitoring subject engagement. By integrating these functions into a single unified platform, the system maintains subject engagement through multi-functional testing while avoiding the complexity of separate independent systems.
Solution Approach 2:
The system automatically monitors subject engagement metrics and dynamically adjusts the interleave of cognitive segments based on detected engagement levels. This self-regulating mechanism reduces the need for complex manual control systems, as the system autonomously manages its own complexity by adapting to subject responses in real-time.
3Loss of time
If the test subject becomes bored or distracted, then test duration may decrease, but measurement precision deteriorates
Solution Approach 1:
The system continuously monitors subject responses and engagement metrics, providing real-time feedback to adjust test administration. When distraction or boredom is detected through response patterns, the system automatically intervenes with engagement-maintaining strategies, ensuring that test completion does not compromise the precision of hearing measurements.

AI summary
Techniques are described for improving results of hearing tests. For example, the hearing tests described herein may be divided into multiple hearing test segments which may be provided to the test subject individually. Additionally, the hearing test may include multiple cognitive test segments that may be interleaved between the hearing test segments to gauge the test subject's awareness level.
