Auditory Training System with Visual Feedback for Hearing Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rehabilitation training methods for hearing-impaired individuals are inefficient and lead to user fatigue due to their monotonous and repetitive nature, failing to effectively address discrepancies between actual sounds and user recognition.
Innovation Solution
A method for treating hearing loss through audiovisual interactive auditory training, which involves providing test sounds with auditory patterns and instructing patients to input corresponding visual patterns, while simultaneously providing synchronized sounds and visual objects to enhance auditory, visual, and motor feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional repetitive listening training is used, then hearing rehabilitation is provided, but user fatigue and boredom occur leading to inefficiency
Solution Approach 1:
The training content dynamically changes based on the patient's performance, difficulty level, and progress. The system adjusts between different training modes (sound recognition, sound generation, imitation) and modifies parameters like sound frequency, duration, and complexity to maintain optimal engagement and effectiveness.
Solution Approach 2:
The system varies multiple parameters including sound frequency ranges, training duration, interval timing, and task complexity. It transitions between different auditory patterns (speech sounds, music tones, environmental sounds) and adjusts visual feedback parameters to prevent monotony and sustain patient interest.
2Measurement precision
If prolonged listening training is provided to reduce perception gap, then recognition accuracy improves, but rehabilitation time increases
Solution Approach 1:
The system provides immediate visual feedback when patients correctly identify sound patterns, displaying the corresponding visual object and providing reinforcement. This instant feedback loop accelerates learning by clearly associating auditory input with visual representation, reducing the time needed to close the perception gap.
Solution Approach 2:
The system presents visual objects before or during sound playback, allowing patients to anticipate and prepare for the sound characteristics. This preliminary visual context helps patients focus their auditory attention more effectively, improving recognition speed and accuracy.
3Adaptability or versatility
If traditional voice-centered training is used, then speech recognition is addressed, but comprehensive auditory function improvement is limited
Solution Approach 1:
The training system handles multiple auditory functions through a unified interface: speech sound recognition, music tone identification, environmental sound classification, and sound generation tasks. The same basic mechanism (sound playback, visual object display, patient response) serves multiple therapeutic purposes.
Solution Approach 2:
The comprehensive training program is divided into distinct modules or levels, each focusing on specific auditory skills. Patients progress through segmented training sequences (vowel recognition, consonant identification, pitch discrimination, timbre recognition) that build upon each other systematically.

AI summary
The present invention relates to a method for treating hearing loss using auditory feedback. The treatment method according to the present invention provides auditory training sounds to hearing-impaired patients along with visual representations of the sound characteristics and receives input from the patients regarding these sound characteristics. Through this approach, it enables integrated training that combines auditory, visual, and motor feedback for hearing-impaired patients. Compared to traditional voice-centered training methods, this provides a more effective and intuitive learning environment, resulting in superior auditory improvement outcomes. Additionally, since the method can identify sound characteristics to which hearing-impaired patients are vulnerable, it allows for customized treatment tailored to each patient. By intensively training these areas, auditory processing can be improved more efficiently. Furthermore, by including linguistic training as part of multisensory auditory training, it can comprehensively enhance music and language recognition abilities. This leads to effective rehabilitation in various aspects, such as improved speech comprehension, better differentiation of everyday sounds, and enhanced quality of music appreciation.
