SOUND VELOCITY CORRECTION DEVICE |
| 摘要 |
Provided a sound velocity correction device including an environmental parameter obtainer that acquires a measured value of a surrounding environmental parameter of a sound collector that collects a sound emitted from a sound source; and a sound velocity corrector that corrects a sound velocity of the sound which is used to form directivity in a directing direction toward the sound source from the sound collector, using the measured value of the surrounding environmental parameter of the sound collector which is acquired by the environmental parameter obtainer. |
