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.
