Stabilizing Audio Azimuth in Varying Acoustic Fidelity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments of varying acoustic fidelity, users of virtual and augmented reality systems experience spatial misalignment and mismatching of audio and video representations, leading to incorrect perception of sound source locations.
Innovation Solution
The apparatus stabilizes apparent azimuth angles of audio signals by manipulating the azimuth of audio signals relative to the position of virtual sound sources towards a midline feature of the user, using circuitry that compensates for human perceptual errors and adjusts based on acoustic fidelity and virtual model accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio signals are presented in virtual environments with varying acoustic fidelity, then the immersive experience is enhanced, but spatial misalignment and mismatching of audio and video representations occur
Solution Approach 1:
The system dynamically adjusts audio signal parameters (azimuth angles) based on the acoustic fidelity of the environment. When acoustic fidelity varies, the apparatus modifies the azimuth parameters of audio signals to compensate for spatial misalignment, ensuring accurate sound source location perception while maintaining the immersive experience across different acoustic conditions
2Measurement precision
If azimuthal angles of audio signals are manipulated to align with visual representations, then spatial alignment is improved, but audio signal processing complexity increases
Solution Approach 1:
The system applies different azimuth angle manipulation strategies to different audio signals based on their specific characteristics and the acoustic environment. Rather than applying a uniform complex processing approach to all signals, the apparatus selectively adjusts azimuth parameters only for audio components that require alignment correction, reducing overall processing complexity while maintaining spatial accuracy

AI summary
An apparatus that facilitates and/or supports stabilizing apparent azimuth angles of audio signals in environments of varying acoustic fidelity may include an eyewear frame dimensioned to be worn by a user. The apparatus may also include circuitry coupled to the eyewear frame and configured to (1) obtain an audio signal originating from a sound source in an environment of the user, (2) manipulate an azimuthal angle of the audio signal relative to a location of the sound source in the environment toward a midline feature of the user, and (3) provide the audio signal for auditory display to the user such that the manipulated azimuthal angle causes the user to perceive the audio signal as originating from the location of the sound source. Various other apparatuses, systems, and methods are also disclosed.
