Hearing Aid Volume-Frequency Adjustment for Audibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing aids and methods for sound output in existing technologies fail to adjust frequencies in conjunction with volume, making it difficult for the hearing impaired or elderly to hear sounds effectively, as increasing volume does not correspondingly adjust frequencies.
Innovation Solution
A hearing aid comprising a microphone, voice processing module, and voice output adjustment module that modifies sound output energy in multiple steps while simultaneously reducing specific frequencies, allowing for step-wise adjustments in volume and frequency to enhance audibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the volume is increased to make sounds audible for the hearing impaired, then the sound intensity improves, but the frequencies remain unchanged making it still difficult to hear
Solution Approach 1:
The patent applies parameter changes by simultaneously adjusting both volume (sound output energy) and frequency parameters. The voice processing module modifies sound output energy across N steps while the voice output adjustment module reduces frequencies correspondingly, ensuring that both parameters are optimized together rather than independently, which resolves the contradiction between increasing volume and maintaining hearing effectiveness
Solution Approach 2:
The system implements dynamics by making the frequency adjustment dependent on the volume adjustment level. As the sound output energy is increased through different steps, the frequency reduction is dynamically adjusted to match, creating a coordinated adaptation that maintains optimal hearing conditions across varying volume levels
2Use of energy by moving object
If the volume is kept at high level to ensure audibility, then the sound intensity improves, but energy consumption increases and comfort decreases
Solution Approach 1:
The patent enables comfortable listening at lower volumes by changing both volume and frequency parameters simultaneously. The voice processing module adjusts sound output energy while the voice output adjustment module modifies frequencies to match human hearing characteristics, allowing effective listening without requiring high volume levels that would cause discomfort

AI summary
A hearing aid and a hearing aid output voice adjustment method thereof are disclosed. The hearing aid includes a microphone, a voice output adjustment module, a voice player, and a voice processing module. The microphone is used for receiving an input voice. The voice player is used for outputting an output voice. The voice processing module is used for receiving the input voice and modifying to the output voice, wherein the voice processing module is used for adjusting sound output energies of at least N steps, wherein the sound output energy of the nth step is greater than that of the n−1th step, 2≤n≤N, N≥3. When the voice processing module adjusts the sound output energy of the Nth step, the voice output adjustment module also simultaneously reduces at least a portion of frequencies of the input voice.
