Noise control device |
| abstract |
A noise control device and method effectively reduce noise throughout a broad frequency band. A noise detecting part can detect the noise from a noise source. A stimulus source control signal is output according to a frequency of the noise detected. A stimulus source is provided based on the stimulus source control signal. A sound absorptivity variable member changes sound absorptivity against the noise responsive to the stimulus source. |
