Accredited anechoic chamber

Our Laboratory Centre offers a comprehensive range of services for testing, measuring, analysing, and researching the vibroacoustic characteristics of machines, electrical devices, installations, equipment, and plant facilities. We perform these services both in our specialized facilities and on-site. At the core of our noise and vibration testing capabilities are two specially designed and constructed anechoic chambers, equipped with advanced measurement instruments that enable precise assessment of various sources of sound and vibration.

Axial fans for transformer cooling

In addition to the anechoic chambers, our laboratories are equipped with the following advanced equipment to successfully conduct complex vibroacoustic measurements and tests:

  • Calibrated sound and vibration sources
  • Sound level meter
  • Two-channel vibration analyzers
  • Multi-channel data recorders and analyzers for noise and vibration
  • Acoustic camera with 42 microphones
  • Computers for automated measurement and data processing
  • Shaker and vibration controller
