Non-Coherent Noise Reduction For Audio Enhancement on Mobile Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240040309 titled 'Non-Coherent Noise Reduction For Audio Enhancement on Mobile Device
Simplified Explanation
The abstract describes a patent application for techniques related to reducing non-coherent noise in audio signals captured by multiple microphones on a mobile device. The proposed method involves receiving signals from multiple audio sensors corresponding to different channels, performing non-coherent noise reduction on the signals based on their respective signal-to-noise ratios, and then combining the signals to generate an output signal.
- The patent application proposes a method for reducing non-coherent noise in audio signals captured by multiple microphones on a mobile device.
- The method involves receiving signals from multiple audio sensors corresponding to different channels.
- A processor then performs non-coherent noise reduction on one or more signals to suppress non-coherent noises based on their respective signal-to-noise ratios.
- The processor combines the signals after noise reduction to generate an output signal.
Potential applications of this technology:
- Mobile devices with multiple microphones, such as smartphones or tablets, could benefit from improved audio quality and noise reduction during voice calls or audio recordings.
- This technology could be used in conference call systems or video conferencing applications to enhance audio clarity and reduce background noise.
- It could also be applied in voice recognition systems or virtual assistants to improve speech recognition accuracy in noisy environments.
Problems solved by this technology:
- Non-coherent noise, such as background noise or interference, can degrade the quality of audio signals captured by multiple microphones.
- This technology addresses the problem of non-coherent noise by applying noise reduction techniques based on the signal-to-noise ratio of each microphone signal.
- By suppressing non-coherent noises, the technology improves the overall audio quality and intelligibility of the captured signals.
Benefits of this technology:
- Improved audio quality: By reducing non-coherent noise, the technology enhances the clarity and intelligibility of audio signals captured by multiple microphones.
- Better user experience: Users of mobile devices or communication systems can enjoy clearer and more natural-sounding audio during voice calls or recordings.
- Enhanced speech recognition: The technology can improve the accuracy of voice recognition systems or virtual assistants by reducing the impact of background noise on speech signals.
Original Abstract Submitted
various techniques pertaining to non-coherent noise reduction for audio enhancement on a multi-microphone mobile device are proposed. a processor receives a plurality of signals from a plurality of audio sensors corresponding to a plurality of channels responsive to sensing by the plurality of audio sensors. the processor then performs a non-coherent noise reduction on one or more signals of the plurality of signals to suppress one or more non-coherent noises in each of the one or more signals based on a respective signal-to-noise ratio (snr) associated with each of the one or more signals. the processor further combines the plurality of signals subsequent the noise reduction to generate an output signal.
