Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio mixing schemes fail to account for human hearing sensitivity differences across various frequency bands, leading to inconsistent loudness perception when adjusting system volume, exacerbating hardware limitations in terminal devices like mobile phones, which affects user experience.
Innovation Solution
An audio mixing method and device that adjust audio mixing parameters based on current system volume and frequency range of audio materials, specifically targeting volume and dynamic range adjustments for different frequency bands to ensure consistent hearing across volume changes, using a processor and memory to execute these adjustments in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed audio mixing scheme is used for all volume levels, then the device complexity is reduced and ease of operation is improved, but the hearing consistency across different volume levels deteriorates
Solution Approach 1:
The patent implements dynamic audio mixing schemes that automatically adjust according to the current system volume level. Different mixing parameters are applied for different volume ranges (e.g., low volume, medium volume, high volume), allowing the audio processing to adapt dynamically to user preferences and listening conditions, thereby maintaining hearing consistency across all volume levels.
Solution Approach 2:
The patent changes key audio mixing parameters such as bass enhancement, mid-range presence, and treble clarity based on the detected system volume level. At lower volumes, parameters are adjusted to maintain clarity and presence, while at higher volumes, parameters are optimized for impact and depth, ensuring consistent perceptual quality across the full volume range.
2Reliability
If frequency-specific volume adjustments are implemented, then hearing consistency across frequency bands is improved, but the device complexity and computational requirements increase
Solution Approach 1:
The patent segments the audio frequency spectrum into distinct bands (e.g., bass, mid-range, treble) and applies independent volume adjustments to each band based on the overall system volume level. This segmentation allows targeted optimization of each frequency range without requiring complex full-spectrum processing, balancing hearing consistency with computational efficiency.
Solution Approach 2:
Different audio processing qualities and parameters are applied to different frequency bands according to their specific characteristics and the current volume level. For example, bass frequencies may receive different enhancement ratios than treble frequencies, with each band optimized locally rather than applying a uniform adjustment across all frequencies.
