Active Noise Control Software Development

  • Client: Korea Research Institute of Standards and Science

  • Development language: LabVIEW

  • Development period: September 2015 to November 2015 (3 months)

  • The current technology is to block railway vehicle noise with sound barriers.

  • In order to overcome this, we developed this software to confirm the possibility of introducing Active Noise Control technology.

  • This technology eliminates noise from railway vehicles using speakers. Using the FXLMS algorithm in an open space, we were able to achieve attenuation of -10dB or more.
