ENVIRONMENTAL NOISE SUPPRESSION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240312474 titled 'ENVIRONMENTAL NOISE SUPPRESSION METHOD
Simplified Explanation:
This patent application describes a voice pick-up arrangement for a wireless headset that improves voice performance in noisy environments. It uses an air microphone and a vibration sensor for sound pickup, with an adaptive filter to subtract noise and enhance the voice signal.
Key Features and Innovation:
- Utilizes an air microphone and vibration sensor for sound pickup
- Adaptive filter subtracts noise from the vibration sensor output
- Monitors noise level to determine filter usage or coefficients
- Beam-forming array suppresses voice component in air microphone audio signal
Potential Applications: This technology can be applied in wireless headsets for clear voice communication in loud environments, such as construction sites, concerts, or busy streets.
Problems Solved: This technology addresses the challenge of maintaining voice clarity in wireless headsets exposed to high levels of environmental noise.
Benefits:
- Improved voice performance in noisy environments
- Enhanced communication clarity in wireless headsets
- Better user experience in challenging acoustic conditions
Commercial Applications: Potential commercial applications include noise-canceling wireless headsets for professionals working in noisy environments, entertainment venues, and public transportation.
Prior Art: Prior art related to this technology may include research on noise-canceling technologies in headsets and adaptive filtering techniques for audio signal processing.
Frequently Updated Research: Stay updated on advancements in noise-canceling technologies, adaptive filtering algorithms, and voice signal processing for wireless communication devices.
Questions about Voice Pick-Up Arrangement Technology: 1. How does the adaptive filter in the voice pick-up arrangement improve voice performance in noisy environments? 2. What are the potential challenges in implementing a beam-forming array in a wireless headset for voice signal processing?
Original Abstract Submitted
a voice pick-up arrangement () provides improved voice performance in a wireless headset () exposed to loud environmental noise. a air microphone () and a vibration sensor () are used for sound pickup. an adaptive filter () may be used to subtract the noise from the vibration sensor output in a subtractor (), thus producing a clear voice signal. a noise level may be monitored and be used for determining whether the adaptive filter is used or for determining the coefficients of the adaptive filter (). a beam-forming array may be used to suppress a voice component of the picked-up air microphone audio signal.
