Acoustic Material Testing

In our acoustic laboratory, we perform many tests for our customers.

Some of the tests are:

  • Airflow measurements complying with ISO 9053/DIN EN 29053 (DIN52213)
  • Sound absorption of materials with an impedance tube ISO10534-2, ASTM E1050
  • Sound transmission loss of materials with an Kundt impedance tube ASTM E2611
  • Sound absorption in reverberation room complying with ISO354 / ISO11654 / ASTM E90-09
  • Sound transmission loss of materials complying with ISO140 / ISO10140 / ASTM E90-09
  • Ultrasonic testing of setting processes for organic and inorganic building products, binders, adhesives
  • Vibration testing on electrodynamic and hydraulic shakers, all test modes supported
  • Structural testing, modal analysis, impact testing
  • Rotating machinery analysis
  • Test stand engineering
  • Data acquisition and condition monitoring
  • Calibration of sound level meters, calibrators, microphones, pistonphones, Vibration meters & accelerometers
  • Sound Power Research and Testing

  • Soud pressure testing
  • Impact Sound Transmission Testing
  • Sound Attenuation testing
  • Hearing protection testing
  • Automotive interior Noise testing
