Solution Overview

Problem

Current hearing ability evaluation methods are time-consuming and uncomfortable for individuals, requiring a large number of hearing evaluation events to accurately determine hearing thresholds, which can be burdensome for both the person being tested and the audiologist.

Innovation Solution

A method and system that utilize a representation of the distribution of hearing ability for a population to establish a hearing ability model by optimizing the stimulus sequence and response observation, allowing for a faster and more accurate estimation of hearing thresholds with fewer evaluation events, using a probabilistic model to update and refine the hearing ability model based on responses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional manual or automatic audiometry methods are used to accurately determine hearing thresholds, then measurement precision is improved, but the duration of the testing procedure increases significantly

Engineering Contradiction:
Improvehearing threshold accuracyVSAvoidtesting procedure duration
Core Design Contradiction:
Measurement precisionVSDuration of action of moving object

Solution Approach 1:

The system performs preliminary actions by establishing a population-based hearing ability model before individual testing. This pre-computed model contains statistical information about hearing ability distributions across populations, which is then used to guide and optimize the individual testing process, reducing the number of evaluation events needed

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously updating the hearing ability model based on observed responses during testing. Each response provides information that refines the model, allowing the system to adaptively determine when sufficient accuracy has been achieved and when to terminate testing, thereby reducing overall testing duration

Inventive Principle:
Principle #23Feedback

2Measurement precision

If a large number of hearing evaluation events are conducted to ensure accurate hearing ability modeling, then measurement precision is improved, but the discomfort and burden on the tested individual increases

Engineering Contradiction:
Improvehearing ability model accuracyVSAvoidtesting discomfort and burden
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system applies partial action by determining when sufficient hearing ability information has been obtained without requiring complete exhaustive testing. By using population-based models and adaptive updating, the system achieves adequate precision with fewer than the traditional maximum number of evaluation events, reducing discomfort while maintaining acceptable accuracy

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If population-based statistical models are used to guide individual hearing evaluation, then productivity is improved by reducing the number of required evaluation events, but device complexity increases due to the probabilistic modeling system

Engineering Contradiction:
Improveevaluation efficiencyVSAvoidprobabilistic modeling system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The population-based hearing ability model serves as an intermediary between the large population dataset and the individual testing process. This intermediary model pre-processes population information into usable statistical forms, simplifying the individual evaluation task while maintaining productivity benefits without requiring direct complex population analysis during testing

Inventive Principle:
Principle #24Intermediary (Mediator)
