NOISE REDUCTION SYSTEM AND NOISE REDUCTION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240098408 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 measurements.
- Microphone, loudspeaker, and processing circuitry are key components of the noise reduction system.
- The system 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, including acoustic characteristics between the loudspeaker and microphone, is measured.
- 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:
- Noise-canceling headphones
- Hands-free communication devices
- Audio recording equipment
Problems Solved

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.
