Noise measurement

RESEARCH EXPERIMENTAL NOISE LABORATORY
The Research Experimental Noise Laboratory is a project established through the collaboration of the Moravian-Silesian Automotive Cluster and VŠB – Technical University of Ostrava. The core of the project is a semi-anechoic room, built on the campus of VŠB – Technical University of Ostrava. It is a unique facility of its kind in the entire Moravian-Silesian region and the surrounding areas.
THE NOISE LABORATORY OFFERS:
  • Multi-channel measurements of all common acoustic quantities using up to 20 channels (sound pressure, intensity, power).
  • Standardized measurements on objects up to dimensions of 1.1m x 1.1m x 1.1m.
  • For informative measurements, the size of the object is limited only by the entrance dimensions of the semi-anechoic room (1.25m x 2m).
  • Noise measurement combined with vibration measurement.
  • Extensive experience with measurements for various applications in the automotive industry.
  • Design and development of methodologies for selected applications, including measurement execution and data processing.
  • Software processing and evaluation of measured data for acoustic design, with the possibility of synchronization with high-speed or thermal cameras.
  • Noise measurement services outside laboratory premises.
  • Utilization of the scientific potential of VŠB – Technical University of Ostrava.
TECHNICAL EQUIPMENT OF THE SEMI-ANECHOIC ROOM:
  • Measurements are performed exclusively using high-end instruments from Brüel & Kjaer and National Instruments.
  • The laboratory is equipped with a 6-channel B&K analyzer and an 8-channel NI analyzer for internal measurements.
  • Available power outlets include 230V/50Hz for measured objects, as well as 12V/10A/AC/DC and 24V/10A/AC/DC for powering automotive electrical components.
  • The semi-anechoic room also features water inlet and outlet systems for operational noise measurements on “white goods” (home appliances).
The Research Experimental Noise Laboratory is located on the second floor of the new canteen (menza) within the VŠB – Technical University of Ostrava campus. The Center for Advanced Innovation Technologies and the headquarters of the Moravian-Silesian Automotive Cluster are located within the same complex.
