Self-Fitting Hearing Aid With Dynamic Noise Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hearing aids require separate hearing tests and fitting operations, which do not consider individual user characteristics or real-world noise environments, leading to suboptimal sound delivery and inefficient hearing measurement processes.
Innovation Solution
A hearing aid system with a microphone, signal processor, and wireless communication unit that allows for self-hearing tests and fittings, using a control terminal to generate and adjust signals by frequency and magnitude, storing user hearing data for direct measurement and automatic fitting adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate hearing tester is used for hearing measurement, then hearing ability can be measured, but the measurement does not reflect actual hearing characteristics with the hearing aid on
Solution Approach 1:
The patent combines the hearing measurement function directly into the hearing aid device itself. The hearing aid generates test signals through its own speaker and receives responses through its own microphone, eliminating the need for separate hearing testers. This integration allows hearing measurements to be performed accurately while the hearing aid is worn, reflecting actual hearing characteristics with the device in use.
Solution Approach 2:
The hearing aid is designed to perform multiple functions: amplification of external sounds, generation of test signals for hearing measurement, and reception of user responses. This multi-functionality allows the single device to both assist hearing and measure hearing ability without requiring additional specialized equipment.
2Reliability
If fitting is performed in a quiet agency environment, then controlled conditions are achieved, but real-world noise environments are not considered
Solution Approach 1:
The patent implements dynamic fitting that adapts to different environmental conditions. The system includes a noise detector that measures ambient noise levels and automatically adjusts fitting parameters based on the detected environment. This allows the hearing aid to provide optimized sound delivery whether the user is in a quiet setting or a noisy real-world environment, eliminating the limitation of static fitting performed only in quiet agencies.
3Manufacturing precision
If complex fitting programs are used, then comprehensive sound processing is achieved, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-fitting functionality where the system automatically performs hearing measurements and determines optimal fitting parameters without requiring manual intervention from professionals. The hearing aid autonomously generates test signals, collects user responses, analyzes hearing thresholds, and configures sound processing parameters automatically. This self-service approach maintains high sound processing quality while dramatically simplifying operation for end users.
Solution Approach 2:
The system performs preliminary hearing measurements and automatic fitting configuration before the user begins using the hearing aid. By pre-determining optimal parameters through automated testing and analysis, the complex sound processing is prepared in advance, eliminating the need for users to manually adjust complex settings during operation.
4Measurement precision
If frequent hearing measurements are performed, then hearing ability changes are detected, but measurement time and complexity increase
Solution Approach 1:
The automated self-measurement system allows users to perform hearing tests independently without requiring professional involvement for each measurement session. The hearing aid autonomously conducts tests, analyzes responses, and updates hearing profiles, enabling frequent measurements to be performed quickly and easily by users themselves, thus detecting hearing changes over time without significant time investment.

AI summary
The present invention relates to a hearing aid allowing a self-hearing test and fitting, and a self-hearing test and fitting system using the same. The hearing aid comprises: a signal generating unit for receiving a command from an external terminal and enabling a receiver to generate a signal having a predetermined size and a predetermined frequency; a hearing storing unit for receiving information on whether a user can hear a signal generated by the signal generating unit and storing the user's hearing; and a fitting unit for adjusting an output of a sound according to the user's hearing. The hearing aid enables an accurate measurement of hearing to be made by directly measuring a user's hearing through the hearing aid, hearing measurement to be easily performed from time to time, and fitting of the hearing aid according to the user's hearing to be automatically made. The self-hearing test and fitting system comprises the hearing aid and a control terminal including a connection sensing unit, a hearing test unit, and an accurate fitting unit, and enables a more accurate control of the hearing aid sound to be made on the basis of the user's hearing.
