Audio Signal Processing for Enduring Noise Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multimedia devices face interference from noise, which can obscure the sound of multimedia content, necessitating an electronic apparatus that effectively adjusts audio signals based on noise levels.
Innovation Solution
An electronic apparatus with a processor that receives audio signals, identifies enduring noise components, and processes the signals by applying adaptive filters and threshold adjustments to enhance voice components or redistribute audio channels, thereby improving sound transmission power.

Engineering Contradiction Analysis
1Object-affected harmful factors
If noise reduction processing is applied to audio signals, then sound quality is improved, but device complexity increases
Solution Approach 1:
The patent segments the audio signal processing into distinct stages: noise detection, enduring component identification, and selective processing application. This segmentation allows the system to process only specific portions of the audio signal that contain enduring noise components, rather than processing the entire signal, thereby reducing overall processing complexity while maintaining effective noise reduction
Solution Approach 2:
The patent applies partial action by selectively processing only the enduring noise components of the audio signal rather than applying comprehensive processing to all audio content. The processor identifies and processes specific time sections where enduring noise is detected, leaving other portions unprocessed, which reduces computational complexity while maintaining effective noise reduction where needed
2Object-affected harmful factors
If audio signal processing is continuously applied, then sound quality is maintained, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by continuously monitoring the audio environment to detect enduring noise components, and only applying processing when such components are detected. The system periodically assesses noise conditions and activates processing only when necessary, rather than continuously processing all audio signals, thereby reducing energy consumption while maintaining sound quality when needed
Solution Approach 2:
The system performs self-service by automatically detecting noise conditions and determining when processing is required without continuous external control. The processor autonomously identifies enduring noise components and activates processing only when noise thresholds are exceeded, enabling the system to manage its own energy consumption based on actual environmental conditions

AI summary
An electronic apparatus is provided. The electronic apparatus includes a microphone and a processor configured to, based on a second sound including a first sound of an audio signal being received through the microphone, obtain a noise about the electronic apparatus based on the audio signal and the second sound, obtain an enduring component of the noise, and based on the enduring component being equal to or greater than a threshold value, process the audio signal.
