Noise/Vibration Testing Laboratory

In 2004, as a first in Turkey, a semi anechoic room with a silent chassis dynamometer in it established in Istanbul Technical University Laboratories of Engines and Vehicles. Since then, testing service is offered in the topics of acoustics and vibration. Acoustics test laboratory is designed so that noise sourced from engine or chassis of the light duty and passenger cars can be measured and modal analysis of parts or systems can be performed. The silent chassis dynamometer enables the testing of vehicles with the constant speed, constant force, wind and vehicle inertia simulation capabilities.

Semi Anechoic Room Specifications:

  • Dimensions: 13 x 8 x 6 m (11 x 6 x 4.5 m)
  • Cut-off frequency: 100 Hz (hassasiyet metodu ISO 3745 – sınıf 1)
  • Background noise (at 100 km/h ): < 55 dB(A)

Engine Dynamometer (AC motor)

  • Max Power: 530 kW
