Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face challenges in comparing audio components with different volume profiles due to varying sound quality and volume scales, leading to skewed perceptions of audio performance.
Innovation Solution
A method and system that automatically match the output volumes of multiple audio components by establishing a reference volume profile, mapping individual volume profiles to this reference, calculating a normalization profile, and adjusting volumes accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio components are sampled with different volume scales, then each component can operate at its optimal volume level, but users cannot accurately compare audio quality due to volume discrepancies
Solution Approach 1:
The system changes the volume parameter by creating individual volume profiles for each audio component that map their unique volume scales to a common reference scale. This allows components with different inherent volume characteristics (driver types, sensitivity, efficiency) to be compared at equivalent volume levels, resolving the contradiction between volume adaptability and comparison accuracy
Solution Approach 2:
A reference volume profile acts as an intermediary between different audio components with varying volume scales. The system establishes this reference profile first, then maps each component's volume profile relative to it, enabling accurate comparison while preserving each component's optimal operating characteristics
2Measurement precision
If users manually adjust volume to match different audio components, then volume comparison becomes possible, but the process is time-consuming and prone to user bias
Solution Approach 1:
The system performs automatic volume profile establishment and mapping without requiring manual user adjustment. The audio components themselves provide the data needed for profiling through automated measurements, eliminating time-consuming manual adjustments and user bias while maintaining high accuracy
Solution Approach 2:
The system uses feedback from automated volume measurements to establish and refine volume profiles. By continuously measuring and adjusting based on actual output, the system achieves accurate volume matching automatically, eliminating both manual time investment and subjective user bias
3Adaptability or versatility
If audio components have different driver types and designs, then each component can produce unique sound characteristics, but volume scales become inconsistent across components
Solution Approach 1:
The reference volume profile serves as a universal standard that can accommodate multiple different audio component types with various driver configurations. By mapping diverse components to this common reference, the system maintains sound quality variety while providing consistent volume comparison across all component types

AI summary
A method for automatically matching output volume of a plurality of audio components, the method comprising: a) establishing reference volume profile at a set of one or more predetermined conditions; b) establishing a first volume profile for a first audio component; c) establishing a second volume profile(s) for a second audio component(s); d) performing a first mapping step of the first volume profile relative to the reference volume profile; e) performing a second mapping step(s) of the second volume profile(s) relative to the reference volume profile; f) calculating a normalization profile; and g) automatically adjusting a volume of the first and/or second audio component to a desired volume.
