NOISE REDUCTION SYSTEM AND NOISE REDUCTION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18176213 titled 'NOISE REDUCTION SYSTEM AND NOISE REDUCTION METHOD
Simplified Explanation
The patent application describes a noise reduction system that includes a microphone, a loudspeaker, and processing circuitry. The system can switch between a control mode and a path characteristic measurement mode to reduce noise based on detected signals and path characteristics.
- Microphone, loudspeaker, and processing circuitry are key components of the noise reduction system.
- The processing circuitry can switch between control mode and path characteristic measurement mode.
- A control filter generates a control signal for the loudspeaker to output a control sound to reduce noise.
- Path characteristic measurement involves measuring the acoustic characteristic between the loudspeaker and the microphone.
- The control filter is generated using the measurement result of the path characteristic and a noise feature signal.
Potential Applications
The technology can be applied in various industries such as telecommunications, audio equipment, automotive, and consumer electronics for noise reduction purposes.
Problems Solved
The system addresses the issue of unwanted noise interference in audio systems, improving the overall sound quality and user experience.
Benefits
- Enhanced audio quality - Improved noise reduction capabilities - Better user experience in noisy environments
Potential Commercial Applications
"Advanced Noise Reduction System for Audio Devices" can be used in headphones, speakers, conference call systems, and smart home devices for superior noise reduction performance.
Possible Prior Art
One possible prior art could be noise-canceling headphones that use similar technology to reduce ambient noise and improve sound quality.
Unanswered Questions
How does the system adapt to different types of noise environments?
The patent application does not specify how the system adjusts its noise reduction capabilities based on varying noise levels or types.
What is the power consumption of the noise reduction system?
The document does not provide information on the energy efficiency or power requirements of the system.
Original Abstract Submitted
According to one embodiment, a noise reduction system includes a microphone, a loudspeaker, and processing circuitry. The processing circuitry switches an operating mode between a control mode and a path characteristic measurement mode, includes a control filter that generates a control signal that causes the loudspeaker to output a control sound for reducing noise, based on a detection signal obtained by detecting a first sound including the noise with the microphone, measures a path characteristic including an acoustic characteristic between the loudspeaker and the microphone, and generates the control filter by using a measurement result of the path characteristic and a noise feature signal including a feature of the noise.
