Personalized Audio Signal Processing for Hearing-Based Sound Tuning

The patent applies parameter changes by adjusting audio signal parameters (equalization filters, dynamic range compression, spatial rendering) based on user-specific hearing profile parameters. The system transforms a generic audio signal into a personalized one by modifying frequency response, dynamic range, and spatial characteristics according to individually measured hearing thresholds and preferences, thereby resolving the contradiction between ease of operation and sound quality.

The patent implements preliminary action by conducting hearing assessments and determining user profiles before actual audio consumption. The system performs hearing threshold measurements, preference surveys, and profile generation in advance, storing these parameters for later application. This preliminary personalization setup enables automatic adaptation of audio signals without requiring user intervention during operation, thus maintaining ease of use while achieving high sound quality.

The patent applies universality by implementing a multi-functional audio processing system that handles hearing assessment, profile generation, signal processing, and adaptive rendering through a single integrated platform. The hearing assessment module serves multiple purposes: it measures thresholds, determines preferences, and generates profiles that are reused across different audio content types. This universal approach consolidates complexity into a unified system rather than requiring separate processing chains for different functions.

The patent uses copying by creating a digital representation (copy) of the user's hearing profile from physical hearing measurements. The system captures actual hearing threshold data and preferences, then creates a simplified digital model that can be stored and repeatedly applied to multiple audio signals. This copying approach allows the complex hearing assessment to be performed once, with the resulting profile model being efficiently reused across numerous audio processing operations, thereby reducing overall system complexity.

The patent applies preliminary action by completing hearing assessments and profile generation before actual audio consumption begins. The system performs hearing threshold measurements, preference surveys, and profile creation in advance, storing these results for immediate application during audio playback. This upfront personalization eliminates the need for real-time adjustments during operation, reducing time loss during actual use while maintaining high speech intelligibility through pre-configured processing parameters.

The patent implements self-service by enabling users to complete hearing assessments and preference surveys at their own pace without requiring professional audiologist intervention. The system provides automated guidance through the assessment process, allows users to input their own preference data, and automatically generates hearing profiles based on their responses. This self-service approach reduces the time investment required compared to traditional clinical assessments while maintaining the quality of personalization.
