Hearing Analysis Apparatus Tinnitus Region Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for tinnitus analysis, such as those described in Korean Patent Publication No. 10-0647310, face challenges in accurately determining the tinnitus region and identifying the point of origin along the sound path.
Innovation Solution
The proposed apparatus and method for hearing analysis involve generating pure tone and complex tone signals at predetermined frequencies, analyzing auditory reactions to these signals, and comparing pure tone recognition information with complex tone recognition information to accurately determine tinnitus regions and their point of origin.

Engineering Contradiction Analysis
1Ease of operation
If a pure tone signal is used for tinnitus testing, then the testing process is simple, but the accuracy of determining tinnitus region and origin is insufficient
Solution Approach 1:
The invention segments the tinnitus detection process by using multiple types of tone signals (pure tone, complex tone, and notched pure tone) instead of relying on a single pure tone signal. Each signal type provides different information about the tinnitus condition, allowing for more precise localization of the tinnitus region and origin while maintaining a systematic and organized testing approach.
Solution Approach 2:
The invention changes the parameters of the test signals by introducing complex tones with different harmonic components and notched pure tones with specific frequency exclusions. These parameter variations in the signal composition enable more accurate identification of tinnitus characteristics and origin points while keeping the testing procedure structured and manageable.
2Measurement precision
If multiple types of tone signals are used for hearing analysis, then the accuracy of tinnitus detection is improved, but the device complexity increases
Solution Approach 1:
The signal generation part is designed with multi-functionality to produce multiple types of tone signals (pure tone, complex tone, notched pure tone) using a unified system architecture. This universal design allows the same device to generate various signal types required for comprehensive tinnitus analysis without requiring separate dedicated systems for each signal type, thereby improving detection accuracy while controlling device complexity.
