Hearing Profile Generation via Passive Audio Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio systems do not account for individual hearing abilities, leading to inadequate sound delivery for users with hearing difficulties across various frequencies, typically assessed in controlled lab settings.
Innovation Solution
An audio system incorporating audio capture devices and processing circuitry that captures user speech, converts it into audio signals, and uses neural networks to identify hearing difficulties, generating a customized hearing profile to adjust audio output and reduce frequency of hearing difficulties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hearing assessment is performed in controlled lab settings, then measurement precision is improved, but device complexity and ease of operation worsen due to requiring specialized equipment and professional settings
Solution Approach 1:
The system enables users to perform their own hearing assessment using a mobile device and audio output device without requiring professional equipment or lab settings. The mobile device captures audio signals, the audio output device plays test tones, and the system automatically processes results to generate a hearing profile, allowing self-service hearing assessment.
Solution Approach 2:
The system uses a mobile device that serves multiple functions: capturing audio signals from the environment, playing test tones through the audio output device, processing the captured signals, and generating hearing profiles. This multi-functional approach eliminates the need for specialized hearing assessment equipment.
2Device complexity
If audio systems produce sound without accounting for individual hearing abilities, then device complexity is reduced, but hearing difficulty frequency increases for users with hearing impairments
Solution Approach 1:
The system captures audio signals from the user's environment, processes them to identify hearing difficulties, generates a hearing profile, and uses this feedback to adjust audio output. The adjusted audio output is then monitored to verify improvement, creating a closed-loop feedback system that continuously optimizes hearing assistance.
Solution Approach 2:
The system adjusts audio output parameters such as frequency response and gain based on the user's hearing profile. By changing these audio parameters to compensate for identified hearing difficulties, the system improves sound delivery without requiring complex hardware modifications.
3Ease of operation
If conventional audio systems do not generate customized hearing profiles, then ease of operation is improved, but adaptability to individual hearing needs deteriorates
Solution Approach 1:
The system performs preliminary hearing assessment by capturing and processing audio signals to generate a customized hearing profile before actual audio playback. This preliminary characterization of the user's hearing abilities allows the system to subsequently tailor audio output without requiring real-time adjustments during operation.

AI summary
An audio system for user hearing assessment includes one or more audio capture devices, and processing circuitry. The one or more audio capture devices are configured to capture audio of a conversation of a user and convert the audio to audio signals. The processing circuitry is configured to use the audio signals to identify multiple conditions associated with user hearing difficulty. The conditions include any of words, phrases, frequencies, or phonemes, and environmental audio conditions that are followed by an indication of user hearing difficulty. The processing circuitry is configured to generate a hearing profile for the user based on the identified conditions associated with user hearing difficulty. The processing circuitry is configured to adjust an operation of an audio output device using the hearing profile to reduce a frequency of user hearing difficulty if the user requires audio enhancement.
