  • Sound collection device, moving body, and sound collection method
    Patent number: 11217263
    Abstract: A sound collection device includes a sensor, a database, a microphone, and an electronic controller. The sensor detects a state of at least one of the sound collection device or a device equipped with the sound collection device, or both. The database is a database of noise sounds. The electronic controller includes a signal processing unit configured to read at least one noise sound from the database based on a detection value of the sensor and carry out a noise reduction process to reduce noise from a sound signal acquired by the microphone based on the at least one noise sound read from the database.

  • Signal processing device, teleconferencing device, and signal processing method
    Patent number: 10978087
    Abstract: A signal processing method performs echo reduction processing on at least one of a collected sound signal of a first microphone, a collected sound signal of a second microphone, or both the collected sound signal of the first microphone and the collected sound signal of the second microphone, and calculates a correlated component between the collected sound signal of the first microphone and the collected sound signal of the second microphone, using a collected sound signal of which echo has been reduced by the an echo reduction processing.
